PCB Piezotronics, Inc. Charge Output Pressure Sensor 112A03

The Charge Output Pressure Sensor model 112A03 from PCB Piezotronics, Inc. features a measurement range of up to 10,000 psi (68,950 kPa) and a sensitivity of 1.20 pC/psi (0.17 pC/kPa). It is designed for high-performance applications with a maximum static pressure rating of 15,000 psi (103,420 kPa) and a resonant frequency of at least 250 kHz. The sensor has a rise time of less than or equal to 2.0 microseconds and a non-linearity of less than or equal to 1.0% full scale. Operating within a temperature range of -100 to +400 °F (-73 to +204 °C), the sensor also has a temperature coefficient of sensitivity of less than or equal to 0.03%/°F. It is constructed with a quartz sensing element and features a welded hermetic seal, ensuring durability in harsh environments. The housing is made of 17-4 stainless steel, and the diaphragm is composed of Invar, providing excellent mechanical stability. The sensor's electrical output is negative for positive pressure, with a capacitance of 21 pF and an insulation resistance of at least 10^12 Ohms at room temperature. It is equipped with a 10-32 coaxial jack for electrical connection and weighs 0.212 oz (6.0 g) with the clamp nut. The product is suitable for applications requiring high sensitivity and reliability in pressure measurement.
