Product Overview
The Honeywell 26PC Series Miniature Pressure Sensors are cost-effective, compensated, and unamplified devices designed for wet or dry media applications. Utilizing a specialized piezoresistive micromachined sensing element, these sensors offer high performance, reliability, and accuracy. They feature a Wheatstone bridge configuration that provides a millivolt output proportional to the applied pressure. The 26PC series accommodates a wide range of pressures from 1 psi to 250 psi and operates within a temperature range of -40 C to 85 C. These RoHS compliant sensors are manufactured to ISO 9001 standards and are suitable for various applications including medical oxygen concentrators, dental chairs, hemodialysis, industrial water control, irrigation, filter monitoring, pressure valves, air compressors, and breathalyzers.
