PCB Piezotronics, Inc. ICP® Pressure Sensor 105C12

The ICP¬Æ Pressure Sensor model 105C12 from PCB Piezotronics, Inc. features a measurement range of 1,000 psi (6,895 kPa) with a sensitivity of 5.0 mV/psi (0.73 mV/kPa). It can withstand a maximum pressure of 7,500 psi (51,700 kPa) and has a resolution of 0.02 psi (0.14 kPa). The sensor exhibits a resonant frequency of at least 250 kHz and a rise time of less than or equal to 2.0 ¬µs. Operating within a temperature range of -100 to +250 ¬8F (-73 to +121 ¬8C), the sensor has a temperature coefficient of sensitivity of less than or equal to 0.09 %/¬8F. It is designed to handle maximum vibration levels of 1,000 g pk and shock levels of 5,000 g pk. The sensor's housing is made of stainless steel, with a diaphragm constructed from 17-4 stainless steel, ensuring durability and reliability. The device requires an excitation voltage of 22 to 30 VDC and operates with a constant current excitation of 2 to 20 mA. It has a positive output polarity for positive pressure measurements and features a welded hermetic seal for environmental protection. The sensor is compact, weighing only 0.055 oz (1.56 g), making it suitable for applications where space is limited.
