PCB Piezotronics, Inc. Pressure Sensor, ICP® 132A35

The PCB Piezotronics 132A35 ICP¬Æ Pressure Sensor is designed for high-frequency applications, featuring a measurement range of 48 psi (330 kPa) and a sensitivity of 140 mV/psi (20.3 mV/kPa). It can withstand a maximum dynamic pressure of 800 psi (5515 kPa) and offers a resolution of 1 mpsi (0.007 kPa). The sensor has a resonant frequency of at least 1000 kHz and a rise time of less than 3 microseconds for incident pressure and 0.5 microseconds for reflected pressure. Operating within a temperature range of 0 to +175 ¬8F (-18 to +79 ¬8C), the sensor requires an excitation voltage of 20 to 30 VDC and a constant current excitation of 2 to 20 mA. Its output impedance is ,⧠100 Ohm, with an output bias voltage between 8 to 14 VDC. The sensing element is made of ceramic, housed in stainless steel, and sealed with epoxy for durability. The sensor is lightweight, weighing only 0.018 oz (0.52 gm), and features pigtail ends for electrical connection. Supplied accessories include a clamp nut and solder adaptor.
