piezoresistive

DESCRIPTION
The TruStability™ DPR Series is a piezoresistive silicon pressure sensor offering a ratiometric analog output for reading pressure over the specified full scale pressure span and temperature range. These sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using an onboard Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz. The DPR Series is calibrated over the temperature range of -20°C to 70°C [-4°F to 185°F].
The sensor is calibrated for operation from a single power supply of 5.0 Vdc. These sensors measure differential or gage pressures. The robust and durable housing, with its industrystandard mounting configuration, along with a choice of flexible electrical terminations, is designed to withstand tough application environments. The sensors’ internal diagnostic functions detect most internal failures, including burst sensors, and may reduce the need for redundant sensors in the system. The DPR Series is intended for use with non-corrosive, nonionic gases, such as air and other dry gases. Custom calibrations, additional pressure ranges or options to extend the performance of these sensors to include non-corrosive, non-ionic liquids is possible. All products are designed and manufactured according to ISO 9001 standards.
