(The Panasonic Corporation pressure sensor can beused with gas.) ■ Rated pressure The pressure value up to which the specifications of the pressure sensor are guaranteed. ■ Maximum applied pressure The maximum pressure that can be applied to the pressure sensor, after which, when the pressure is returned to below the rated pressure range, the specifications of the pressure sensor are guaranteed. ■ Temperature compensation range The temperature range across which the specification values of the pressure sensor are guaranteed. ■ Drive current (voltage) The supply current (voltage) required to drive a pressure sensor. ■ Output span voltage The difference between the rated output voltage and the offset voltage. The output span voltage is also called the full-scale voltage (FS). ■ Offset voltage The output voltage of a pressure sensor when no pressure is applied. ■ Rated pressure output voltage Output voltage when rated pressure is applied. ■ Linearity When the pressure is varied from no load to the rated pressure, the linearity is the amount of shift between the straight line that joins the no-load voltage value and the rated pressure voltage value (expressed as the ratio of the amount of shift (D1) at half of the rated pressure value with respect to the full scale voltage (FS)). ■ Output hysteresis D1 FS D2 Offset voltage No load 1/2 rated pressure Rated pressure output voltage Output voltage The ratio of the difference (D2) in the noload output voltages when the pressure is varied from no load to the rated pressure then reduced back to no load, with respect to the full scale voltage (FS). Rated pressure ■ Offset voltage temperature characteristic The variation of the offset voltage with changes in ambient temperature. The difference between the offset voltage at the standard temperature and the offset values at the compensation lower limit temperature (low temperature) (D1) and compensation upper limit temperature (high temperature) (D2) are obtained, and the offset voltage temperature characteristic is expressed as the ratio of the larger of these two differences (absolute) with respect to the full scale voltage (FS). Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. 31-Mar-20 Glossary of Common Terms for Pressure Sensors Explanation of terms ■ Temperature sensitivity characteristic Output voltage The variation of the sensitivity with changes in ambient temperature (variation in full　scale (FS)). The difference between the full scale voltage at the standard　temperature (FS) and the full scale values at the compensation lower limit temperature (low temperature) (FS1) and compensation upper limit temperature (high temperature) (FS2) are obtained, and the offset voltage temperature characteristic is expressed as the ratio of the larger of these two differences (FS1 - FS and FS2 - FS (absolute)) with respect to the full scale voltage (FS). Compensation upper limit temperature FS3 Δ2 Standard temperature FS2 FS1 Δ1 No load Compensation lower limit temperature Rated pressure ■ Bridge resistance Refers to the resistance value of a piezo resistance formed on a monolithic silicon substrate. For example, the values of the resistances R1 to R4 in the bridge are typically 5 kΩ each. ✽ When the resistances of the resistive elements R1 to R4 that comprise the bridge are 5 kΩ each, the equivalent composite resistance of the bridge is 5kΩ (3 kΩ bridges are also available). R2 R1 R3 R4 The bridge resistance is the resistance of the four resistive elements that make up the bridge expressed as one combined resistance. ■ Overall accuracy Accuracy of offset voltage and rated pressure output voltage within the temperature compensation range.

Do not use the sensor with a harmful medium, such as a corrosive gas, a combustible gas, or a toxic gas. There is a possibility that a tiny amount of the harmful medium will leak out and exert a harmful effect on the surrounding environment and the human body. ■ The sensor does not have a waterproof structure. Avoid using the sensor in a place where water, etc., may splash on the sensor or an environment where dew concentrates on the sensor. When water on the sensor freezes, it may lead to a change in the output from the sensor or even the destruction of the sensor. ■ Because of the structural features of the sensor, the sensor output fluctuates when the sensor is exposed to light. Avoid the sensor being exposed to light, etc., especially, when pressure is applied to the sensor through a transparent tube. ■ Do not use the sensor in a situation where high-frequency vibrations, such as ultrasonic waves, are applied to the sensor. ■ The sensor may malfunction when exposed to static electricity, lightening, or electric noise from a cellular phone, radio transmitter, broadcasting station, etc. ■ Since the sensor is open to the ambient air, be careful not to let cleaning solution flow into the sensor. Do not clean the sensor by using ultrasonic waves. It may cause the sensor to fail. 　Handling conditions ■ Use the sensor in the rated voltage range. Applying voltage outside the rated voltage range to the sensor can cause an accident or breakage of the sensor. Select the way the sensor, lead-in tube, etc., are fixed in accordance with the pressure being applied to the sensor. If you have any question, please feel free to contact us. ■ The sensor has a built-in sensor chip located close to the pressure lead-in port. Inserting a foreign object, such as a needle, in the pressure lead-in port damages the chip or blocks up the lead-in port. Never do this. Do not block up the pressure lead-in port. ■ When coating the board carrying the sensor with a potting agent, etc., make sure that the potting agent does not go into the pressure lead-in port and the ambient pressure lead-in port. Thermal expansion/shrinkage of a resin coating the sensor applies stress to the sensor. Use a resin with elasticity as a sealing agent (potting agent) after sufficiently evaluating its properties. ■ The sensor may be destroyed by static electricity. Keep the sensor in a storage condition in which its terminals are short-circuited via a conductive material or the whole sensor is wrapped with aluminum foil, etc. Because a plastic container becomes charged with static electricity easily, avoid using a plastic container for storage or transportation of the sensor. When using the sensor, let surrounding objects release static electricity safely by grounding the operator, charged objects on the table, etc. 　Circuit design and circuit board design ■ The sensor has its resistance gauge driven by constant current, converting the pressure into corresponding voltage, which is then amplified on a necessary basis. In general, the air pressure transmission method for low-pressure is different from that for high-pressure. The following diagrams shows a typical circuit and an air pressure transmission method that are generally adopted. ＜Use circuit＞ Constant current circuit Pressure sensor Amplifier circuit ＜Air pressure transmission method＞ Low-pressure case (4.9 kPa to 98.1 kPa) High-pressure case (196.0 kPa to 980.7 kPa) Printed board Printed board O-ring Tube Pressure lead-in tube 30-Jun-23 Matters to Be Observed When Using This Product ■ Adopt a printed board land where the sensor can be affixed properly. Select a solid pressure lead-in tube and fix the sensor firmly so that no pressure leaks. Do not block the pressure lead-in tube. ■ In the high-pressure method, the tube may come off due to incoming high pressure. In this case, attach a solid lead-in tube to the sensor with an O-ring interposed therebetween. 　Mounting conditions ■ A sensor has a small structure with a small heat capacity. When soldering the sensor, keep the effects of external heat on the sensor as small as possible. A sensor exposed to intensive heat thermally deforms, which may lead to breakage or change in characteristics. ■ Use non-corrosive, rosin-based solder flux. The sensor is structured to be open to the ambient air. Make sure that solder flux does not flow into the sensor. ■ Perform manual soldering in the following manner: clean the soldering iron tip sufficiently and then finish soldering, with the soldering iron tip heated to 260 ℃ to 300 ℃ (30 W), within 5 seconds. Do not apply a load to the sensor terminals. It may change the output from the sensor. ■ Perform flow soldering (DIP terminal type) with a flow soldering tank temperature kept at 260 ℃ or lower and within 5 seconds. When the sensor is mounted on a board with a small heat capacity, the sensor may thermally deform when exposed to soldering heat. In this case, avoid flow soldering. ■ In the case of reflow soldering (SMD terminal type), we recommend solder-paste screen printing as a solder paste printing method. ■ For a footprint pattern on the printed board, refer to the printed board recommended specification diagram. Because self-alignment of solder is insufficient in some cases, carefully align the terminals of the sensor and the pattern. ■ The recommended reflow temperature profile is shown below. The temperature measurement shown in the temperature profile is the value measured at a part of board that is close to the terminals. Main heating Temperature 230°C 220°C Preheating 150°C 60 seconds or less 10 seconds or Time ■ The front end of the pressure lead-in port may melt or deform under high temperature, depending on the equipment or conditions. Make sure to conduct a confirmation test under the actual mounting conditions. ■ Complete rework on a soldered part in a single process. When reworking a solder bridge, use a solder iron with a flat tip and do not apply any additional solder flux. Use a solder iron with a tip temperature equal to or lower than the tip temperature specified in the specification sheet. ■ A warped printed board applies stress to the sensor, which may change the characteristics of the sensor. Conduct a characteristics confirmation test after the soldering process. When cutting or folding the board after mounting the sensor on the board, be careful that no stress is applied to the soldered area. ■ The sensor has external terminals exposed from its body. A metal piece, etc., coming in contact with the exposed terminals, causes problems with output from the terminals. Prevent metal pieces, bare hands, etc., from coming in contact with the terminals. Excessive force applied to the terminals deforms the terminals, thus impairing the solderability of the sensor. Do not drop the sensor, and do not handle it roughly, either. ■ When coating the board to prevent the deterioration of insulation properties after the soldering process, make sure 　 that no chemical sticks to the sensor. 30-Jun-23
