Description of product

Description

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 Honeywell sensors have a ±1.6mbar to ±25mbar / ±160Pa to ±2.5kPa / ±0.5inH2O to ±10inH2O pressure range. DPR sensors are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1kHz. The series is calibrated over a -20°C to 70°C temperature range. The sensor is calibrated for operation from a single power supply of 5.0VDC. These sensors measure differential or gauge pressures. The robust and durable housing is designed to withstand harsh application environments.
