Honeywell 24PCEFA6D Miniature Differential Pressure Sensor 0.5 PSI Dual Port 4-SIP

The Honeywell 24PCEFA6D is an ultra-low, uncompensated miniature board-mount differential pressure sensor designed for precise wet-to-wet measurements up to 0.5 PSI. Featuring a dual axial barbless port layout and a 4-pin SIP module package, this highly sensitive millivolt device fits standard engineering layouts similar to the 24PCFFA6G series but specializes in micro-differential sensing for medical respirators and environmental monitors.

Achieve superior accuracy in micro-fluidic control systems with the genuine Honeywell 24PCEFA6D low-pressure differential sensor. As a core component of the highly versatile 24PC platform, this device utilizes an advanced piezoresistive micromachined silicon die to deliver exceptional stability and capture micro-level pressure variations across a narrow range of plus or minus 0.5 PSI.
While higher-range frameworks like the 24PCFFA6G are optimized for coarse industrial pneumatic loops, the 24PCEFA6D focuses entirely on ultra-low differential resolution. It features two axial barbless ports on opposite sides with a robust fluorosilicone inner seal, allowing direct differential measurement of both liquids and gases on both ports. The sensor architecture operates via an unamplified Wheatstone bridge circuit, granting instrumentation engineers complete freedom to establish custom temperature compensation networks, span calibration coefficients, and external operational amplifier circuits.
