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 use an onboard ASIC to calibrate and temperature-compensate sensor offset, sensitivity, temperature effects, and accuracy errors. The calibrated pressure output is updated at approximately 1kHz for analog and 2kHz for digital. All products are designed and manufactured in accordance with ISO 9001 standards.

• Dry gas option: Input ports are limited to non-corrosive, non-ionic media and must not be exposed to condensation. Media must be 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, enabling use with non-corrosive liquids and applications where condensation may occur. Since port P2 is designed for non-corrosive liquids, this option is typically suitable for wet-wet differential pressure sensing.
