Honeywell Sensing & Control DPR TruStability™ Board-Mount Pressure Sensors

Honeywell Sensing & Control DPR TruStability™ Board-Mount Pressure Sensors are piezoresistive silicon sensors offering a ratiometric analog output for reading pressure over the specified full-scale pressure span and temperature range. These sensors have a ±1.6mbar to ±25mbar / ±160Pa to ±2.5kPa / ±0.5inH2O to ±10inH2O pressure range. The DPR series is 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 1kHz. Honeywell DPR TruStability board-mount pressure sensors are calibrated for operation from a single power supply of 5VDC and measure differential or gauge pressures. The robust and durable housing is designed to withstand harsh application environments.
