One Series Electronic Switch+ Transmitter Overview

UE's One Series line of programmable electronic pressure and temperature products sets new standards for quality, reliability, and SIL capability.

The One Series provides explosion (flame)-proof, intrinsically safe and non-incentive models that monitor gage pressure, differential pressure or temperature. An advanced low-power microcontroller provides four SMART model platforms.





Applications


​  Natural Gas Monitoring

 



Seal Pressure Monitoring


 



Cryogenic monitoring for LNG storage and transport.
