Overview

24PC Series, uncompensated/unamplified, wet/wet differential, ±15 psi, SMT, straight port.

The 24PC SMT (Surface Mount Technology) Series pressure sensors provide a small, low cost, high value, pressure sensing solution for use with printed circuit boards (PCBs). Based on the long established reliability and accuracy of the 26PC pressure sensor, the 24PC SMT offers reduced size with true SMT capability. The smaller size reduces the sensor's footprint on the PCB, thereby reducing the size of the PCB. The 24PC SMT is designed to be used with other SMT components on a PCB, helping to lower installation costs and eliminate secondary operations.

The sensor features Wheatstone bridge construction, silicon piezoresistive technology, and ratiometric output for proven application flexibility, design simplicity and ease of manufacture.

Although designed for the medical industry, the 24PC SMT pressure sensor may be applied in almost any application that requires a surface mount pressure sensor.
