DP5-01.htm 1/1,000 sec. The advantage of the fastest response in the industry High speed in response to the needs of the times. Achieves 1 ms response time, the fastest in the industry. file:///G|/DP5/DP5-forweb.htm (1 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm In response to the needs of the times and amid the continuing quest for faster and more efficient production lines comes the DP5/DPH series, a digital pressure sensor with a detachable head. The response time of 1 ms makes this the fastest sensor in the industry. In addition to the fast response time, the detachable head represents a major breakthough for ease of operation and maintenance. Independent Use of Sensor Head Possible Data can be controlled by taking the analog voltage output (1 to 5V) from the sensor head and sending it to a digital panel meter. Extremely Small, Extremely Light Head (6g) Sensor Head with Operation Indicator The sensor head is also equipped with an operation indicator. Output ON/OFF can be checked at the sensor head and operation can be checked at the suction head. (Linked to Comparative Output 1) Convenient Intermediate Cable An intermediate cable with connectors for connecting the sensor head and the controller makes operation and maintenance easier. ● Standard or flexible intermediate cables are available in 2m, 3m and 5m sizes. ● Use the flexible intermediate cable when the sensor head is attached to moving sections. file:///G|/DP5/DP5-forweb.htm (2 of 20) [6/11/2001 11:14:04 AM] Easy Mounting, Mobile Pressure Port The head's pressure port can be rotated independently (freeturning) from the sensor head. In addition to being easy to mount, the cable can be positioned in any direction. DP5-01.htm Super fast 1 ms Mounting the detachable head close to the detecting section minimizes piping and enables a response time of 1 ms, the fastest in the industry, as well as greatly decreasing tact time delay. In addition, the ultra-small and light-weight design of the head means it can be easily mounted on moving sections. A Total of 10 Head Variations to Meet all Production Demands Vacuum pressure type Positive pressure type Compound pressure type (0 to -101.3kPa) (0 to 1.000MPa) (-100.0 to 100.0kPa) ● M5 male thread ● R (PT) 1/8 male thread/ M5 female thread ● ● NPT 1/8 male thread/ 10-32UNF female thread 10-32UNF male thread ● M5 female thread ● M5 female thread ● R (PT) 1/8 male thread/ M5 female thread ● R (PT) 1/8 male thread/ M5 female thread ● NPT 1/8 male thread/ 10-32UNF female thread ● NPT 1/8 male thread/ 10-32UNF female thread Both NPN and PNP outputs are available so that this sensor can be used anywhere in the world. This sensor conforms to the CE marking EMC Directive and has obtained UL recognition. Detachable head means layout freedom. Use it any way you want. Light-weight, Compact Design The controller inherits its light-weight compact design from the popular compact digital pressure sensor, the DP4 series. The control panel setup is inexpensive and requires minimal space. User-friendly Two-color Digital Display The user-friendly two-color digital display changes color when output changes (ON/OFF), making it easy to check operation status at a glance. The display color can be linked to Comparative Output 1 or to Comparative Output 2. Two Independent Outputs Plus Analog Voltage Output In addition to two independent outputs (ON/OFF), an analog voltage output (1 to 5V) is also available. The different outputs allow you to create solutions for a wide variety of applications. file:///G|/DP5/DP5-forweb.htm (3 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm Two Operation Indicators There are two operation indicators that light respectively when Comparative Output 1 or Comparative Output 2 is ON. These are convenient for frequent operation checks. Sensor Head Auto-recognition The sensor head's auto-recognition function means that you don't have to manually set the head type at the controller, saving you valuable time. Handy Attachments for Flexible Controller Mounting Panel Mounting Bracket is Supplied A panel mounting bracket is enclosed that allows simple mounting of the controller onto the panel surface. This makes for a more cost-effective system. DIN Rail Mounting Bracket Is Available The controller can even be mounted on a 35mm width DIN rail by using the optional DIN rail mounting bracket (MS-DP2). It can be fitted in a narrow space inside your equipment because it can be mounted from four different directions. Can be Used with Panel Thicknesses from 1 to 6mm Since the panel thicknesses can be from 1 to 6mm, the controller can be mounted on thick, resin-made panels. Select from Six Pressure Units Select the pressure unit from six different systems to suit your requirements. The selectable pressure units differ with the sensor type. When the pressure unit is changed, the measured pressure value and the set values are automatically adjusted. Note: 'MPa' when combining with DPH-A02, DPH-A12 or DPH-A22 positive pressure sensor head. Full Range of Functions in a Compact Body Gives You a Wide Variety of Control Options file:///G|/DP5/DP5-forweb.htm (4 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm The only sensor in the industry with a leak test mode. Four output modes give you complete control. Leak Test Mode It is suitable for a leak test since Comparative Output 1 can be set to the hysteresis mode and Comparative Output 2 can be set to the window comparator mode. Using it along with the autoreference/remote zero-adjustment functions ensures a reliable leak test. Hysteresis mode The hysteresis of the comparative outputs can be set arbitrarily by the set values for the ON/OFF control. Window comparator mode The comparative output can be turned ON or OFF by a pressure which is within the set pressure range. Forced output mode The comparative outputs are forcibly maintained at OFF level in the sensing mode, irrespective of the set values. This is convenient for displaying the pressure value without using the comparative outputs. Since the comparative outputs can be forcibly switched ON or OFF with key operation without actually applying pressure this mode is suitable for an operation or a start-up check. file:///G|/DP5/DP5-forweb.htm (5 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm Equipped with auto-reference and remote zero-adjustment function. More accurate pressure control with minimal effort. If the reference pressure of the equipment changes the auto-reference function can adjust the threshold levels by the amount of change and the remote zero adjustment function can reset the display value to zero via external input. These functions are ideal for places where the reference pressure fluctuates significantly or where precise settings are desired. Example: When leak test mode is applied, Comparative Output 1 detects the filling pressure and Comparative Output 2 detects the leakage.

Its use is not intended or designed to protect life or prevent bodily injury or property damage from dangerous parts of machinery. It is a normal pressure detection sensor. The DPH series is designed for use with non-corrosive gases. It cannot be used with liquids or with corrosive gas. Functional description ● Wiring ● Make certain that the power is off before the wiring is installed. Verify that the supply voltage variation is within the rating. ● f power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. ● In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this controller, connect the frame ground file:///G|/DP5/DP5-forweb.htm (11 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm (FG.) terminal of the equipment to an actual ground. ● If the power supply generates a surge, connect a surge absorber to the power supply to absorb the surge. ● Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This could cause malfunction due to induction. ● In order to reduce noise, make the wiring as short as possible. Improper wiring will damage the sensor. Other Precautions ● ● Use within the rated pressure range. Do not apply pressure exceeding the pressure limits. Excessive pressure will damage the diaphragm and the unit will not function. ● Do not use during the initial transient time (DP5: 3 sec. approx., DPH: 50ms approx.) after the power supply is switched on. ● Avoid dust, dirt, and steam. Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. ● ● Do not insert wires, etc. into the pressure port. This could damage the diaphragm and the unit will not function. ● Do not operate the keys with pointed or sharp objects. DP5/DPH PRECAUTIONS FOR PROPER USE file:///G|/DP5/DP5-forweb.htm (12 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm Setting ● If key-protect has been set, make certain that you release the key-protect before operating the keys. (Please refer to "Key-protect function" later in this section.) ● Pressure value setting can be done only if the output mode is set to the hysteresis mode, window comparator mode or the leak test mode. Pressure values cannot be set if the output mode is set to the forced output mode. ● Set Values P-1 to P-4 can be common for all the output modes. For the positive pressure type and the compound pressure type, Set Value P-2 should be set towards the higher pressure side with respect to Set Value P-1 and Set Value P-4 should be set towards the higher pressure side with respect to Set Value P-3. Also, in the vacuum pressure type, Set Value P-2 should be set towards the higher vacuum side with respect to Set Value P-1 and Set Value P-4 should be set towards the higher vacuum side with respect to Set Value P-3. ● ● ● ● The auto-reference function affects only Set Value P-3 and Set Value P-4. Set Value P-A is the pressure value when the auto-reference input or the remote zero-adjustment input is applied. When the auto-reference input or the remote zero-adjustment input is not applied, Set Value P-A is zero. The set conditions are written and stored in an EEPROM. Note that the EEPROM has a guaranteed lifespan of 100,000 write operation cycles. Since the auto-reference input value and the remote zero-adjustment input value are not stored in the EEPROM, they are not included in the number of write operation cycles. file:///G|/DP5/DP5-forweb.htm (13 of 20) [6/11/2001 11:14:04 AM] DP5-01.htm DP5/DPH PRECAUTIONS FOR PROPER USE Auto-reference function ● Operation Chart Auto-reference function corrects Set Value P-3 taking the pressure measured at the time of auto-reference input as the reference pressure. When there is no auto-reference input, the atmospheric pressure is taken as the reference pressure for Set Value P-3 and Set Value P-4. ● At the time of auto-reference input, the pressure value detected at that instant is temporarily recorded as Set Value P-A and becomes the reference pressure. Auto-reference input: 50kPa Output mode: Hysteresis mode Note: In the hysteresis mode, Set Value P-3 and Set Value P-4 are shifted. The output is set to the window comparator mode or the leak test mode. With Set Value P-A as the reference pressure, Set Value P-3 and Set Value P-4 are automatically corrected to 'Set Value P-3 + Set Value PA' and 'Set Value P-4 + Set Value P-A' respectively. Settable range and set pressure range after correction ● ● ● Maintain the pressure at a constant level for at least 2ms after the auto-reference input is changed to Low (High in case of PNP output type). If used in a transient state it will not operate properly.. ● Use Comparative Output 2 at least 'set response time + 2ms' after the auto-reference input is made changed to Low (High in case of PNP output type). ● At the time of auto-reference input, displayed on the 3-1/2 digit display for approximately 1 second. ● The auto-reference input value (Set Value P-A) The settable range of Set Value P-3 and Set Value P-4 is wider than the rated pressure range to allow the auto-reference function. file:///G|/DP5/DP5-forweb.htm (14 of 20) [6/11/2001 11:14:04 AM] is DP5-01.htm ● At the time of auto-reference input, if the corrected set value exceeds the set pressure range, the set value is automatically corrected to be within the set pressure range. Please make certain that the set pressure range is not exceeded. changes to zero when the power supply is switched off and then on again. ● Although it is not possible to display the corrected 'Set Value P-3' and 'Set Value P-4', it is possible to display the auto-reference input value (Set Value P-A).

Peak hold & bottom hold function Note: In the leak test mode, the zero-adjustment function is applied only to Comparative Output 2. Comparative Output 1 operates with the atmospheric pressure as the reference. ● Maintain the pressure at a constant level for at least 2ms after the remote zero-adjustment input is changed to Low (High in case of PNP output type). If used in a transient state, it will result in wrong operation. ● Use the comparative outputs at least 'set response time + 2ms' after the remote zero adjustment input is changed to Low (High in case of PNP output type). ● At the time of remote zero-adjustment input, is displayed on the 3-1/2 digit display for approximately 1 second. ● If the power supply is switched off and then on again, the remote zero-adjustment input value is cleared and the sensor returns to normal operation with atmospheric pressure as the reference. ● Peak hold and bottom hold functions enable the display of the peak value (maximum pressure value) and the bottom value (minimum pressure value) of the varying measured pressure. ● These functions are convenient for finding the pressure variation range or determining the reference for pressure settings. ● Please note that the peak value and the bottom value data is erased when it is no longer displayed.
