Request Information Favorite
The low cost US300 Series incorporates stainless steel isolation, and provides a wide choice of standard pressure ranges and electrical outputs in a very compact package. 

This product uses MEAS UltraStable™ technology that provides stability over a wide temperature range, performance previously available only in much higher priced sensors. The modular design is adaptable to a wide variety of pressure ports and electrical connectors. Standard outputs include 0-10 mV/V, 0.5-4.5 V ratiometric, 1-5 V regulated and 4-20 mA current loop.
