Product Overview
The Honeywell 26PC Series Miniature Low Pressure Flow-Through Sensors are compensated and unamplified devices designed for accurate and reliable pressure measurement. Utilizing a specialized piezoresistive micromachined sensing element in a Wheatstone bridge configuration, these sensors offer high performance across a range of pressure sensing from 1 psi to 100 psi. Their flow-through design minimizes dead space, inhibits bacterial growth, and reduces the need for additional connections, making them a cost-effective alternative to stainless steel packages. Available in various pressure ranges, measurement types (absolute, differential, wet-wet differential, gage, and vacuum gage), and termination configurations, these sensors are suitable for a wide array of applications, including medical hemodialysis for monitoring blood filtration pressure. They are designed and manufactured according to ISO 9001 standards.
