First WirelessHART Toxic or Combustible Gas Detector


When operators involved in oil & gas production, transportation and storage wanted to monitor gas emissions without the time, cost, and disruption of adding wired detectors, UE product development used this voice of the customer to develop a simple to install, untethered HART gas detector that was operational within hours of deployment.

First SIL2 Smart Switch with Integrated Transmitter, Safety Relay, Trip Alarm, and Logic Solver

As SIS spread beyond the process plant into field applications, operators lacked infra­structure to support a safety system. Listening to operator requirements, UE was able to design an “all-in-one,” SIL-certified device that not only met the safety requirements, but eliminated the complexity and additional equipment associated with SIS implementation.

Only Loop Powered Electronic Switch with Plugged Port Detection

Two common problems for operators are 1) blocked pressure ports on instruments due to process debris, slurries or media build-up and 2) when block and bleed valves are closed during maintenance. There was a need for a diagnostic that alerted operators to either of these conditions, and eliminated “live-zero” signals, blind process monitoring, and long maintenance cycles.
