Product Attributes

Introduction

The ABP series are piezoresistive silicon pressure sensors that provide ratiometric analog or digital output for reading pressure within a specified full-scale pressure span and temperature range. They are calibrated and temperature-compensated via an onboard ASIC to correct for sensor offset, sensitivity, temperature effects, and accuracy errors (including non-linearity, repeatability, and hysteresis). The pressure-calibrated output update rate is approximately 1 kHz for analog and 2 kHz for digital. All products are designed and manufactured in accordance with ISO 9001.

• Dry gas option: The inlet port is limited to non-corrosive, non-ionic media (e.g., dry air, gases) and must not be exposed to condensation. Gas is limited to media compatible with high-temperature polyamide, silicone, alumina ceramic, silicon, gold, and glass.
• Liquid media option: Includes an additional silicone-based gel coating to protect the electronics beneath port P1, making it suitable for use with non-corrosive liquids (e.g., water and brine) and applications where condensation may occur. Since port P2 is designed for non-corrosive liquids, this option is typically intended for wet-wet differential pressure sensing.
