Mounting Use lands on the printed-circuit boards to which the sensor can be securely fixed. 2. Soldering 1) Due to its small size, the thermal capacity of the pressure sensor DIP type is low. Therefore, take steps to minimize the effects of external heat. Dip soldering bath: Max. 260°C 500°F, 5 sec. Soldering iron: 260 to 300°C 500 to 572°F (30W) within 5 sec. 2) Use a non-corrosive resin type of flux. Since the pressure sensor DIP type is exposed to the atmosphere, do not allow flux to enter inside. 3. Cleaning 1) Since the pressure sensor chip is exposed to the atmosphere, do not allow cleaning fluid to enter inside. 2) Avoid ultrasonic cleaning since this may cause breaks or disconnections in the wiring. 4. Environment Consult with us before using or storing the pressure sensor chip in a place exposed to corrosive gases (such as the gases given off by organic solvents, sulfites, hydrogen sulfides, etc.) which will adversely affect the performance of the pressure sensor chip. 5. Quality check under actual loading conditions 1) To assure reliability, check the sensor under actual loading conditions. Avoid any situation that may adversely affect its performance. 2) As for test data, please contact us. 6. Other handling precautions 1) That using the wrong pressure range or mounting method may result in accidents. 2) Air can be used directly as a pressure medium. Consult with us before using a corrosive gas (such as a gas given off by an organic solvent, sulfite or hydrogen sulfide) as the pressure medium. 3) The pressure sensor chip is positioned inside the pressure inlet. Never poke wires or other foreign matter through the pressure inlet since they may damage the chip or block the inlet. Avoid use when the atmospheric pressure inlet is blocked. 4) Leave pin No. 4 unconnected since the pressure sensor chip may be damaged if a voltage is applied to this pin. 5) Use an operating pressure which is within the rated pressure range. Using a pressure beyond this range may cause damage. 6) Since this pressure sensor chip does not have a water-proof construction, consult with us if it is to be used in a location where it may be sprayed with water, etc. 7) Avoid using the pressure sensor chip in an environment where condensation may form. Furthermore, its output may fluctuate if any moisture adhering to it freezes. 8) The pressure sensor chip is constructed in such a way that its output will fluctuate when it is exposed to light. Especially when pressure is to be applied by means of a transparent tube, take steps to prevent the pressure sensor chip from being exposed to light. 9) Avoid using the pressure sensor chip where it will be susceptible to ultrasonic or other high-frequency vibration. 10) Since static charge can damage the pressure sensor chip, bear in mind the following handling precautions. • When storing the pressure sensor chips, use a conductive material to short the pins or wrap the entire chip in aluminum foil. Plastic containers should not be used to store or transport the chips since they readily become charged. • When using the pressure sensor chips, all the charged articles on the bench surface and the work personnel should be grounded so that any ambient static will be safely discharged. 11) Due to the pressures involved, give due consideration to the securing of the pressure sensor DIP type and to the securing and selection of the inlet tube. Consult us if you have any queries. APPLICATION CIRCUIT DIAGRAM (EXAMPLE) The pressure sensor is designed to convert a voltage by means of constant current drive and then, if necessary, it amplifies the voltage for use. The circuit shown below is a typical example of a circuit in which the pressure sensor is used. Constant current circuit unit Pressure sensor MOUNTING METHOD The general method for transmitting air pressures differs depending on whether the pressure is low or high. • Checkpoints for use Select a pressure inlet pipe which is sturdy enough to prevent pressure leaks. Fix the pressure inlet pipe securely so as to prevent pressure leaks. Do not block the pressure inlet pipe. Methods of transmitting air pressures When the pressure is low (4.9 to 98.1 kPa) Printedcircuit board When the pressure is high (196.1 to 980.7 kPa) Printedcircuit board O-ring Tube Pressure inlet pipe Amplifier circuit unit If a tube is used as the pressure inlet pipe, it may become disengaged. Therefore, use a sturdy tube and secure it using O-rings. OP AMP OP AMP OP AMP 12/1/2002 All Rights Reserved, © Copyright Matsushita Electric Works, Ltd.
