Honeywell TruStability® RSC Board-Mount Pressure Sensors

Honeywell TruStability® RSC Board-Mount Pressure Sensors are piezoresistive silicon pressure sensors that provide a digital output for reading pressure over the specified full-scale pressure span and temperature range. These sensors are calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using a 24-bit analog-to-digital converter with integrated EEPROM. Over an SPI interface, pressure data may be acquired at rates between 20 and 2000 samples per second. Honeywell TruStability RSC Board-Mount Pressure Sensors are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases. These devices are designed and manufactured according to ISO 9001 standards, and are REACH and RoHS compliant.
