One Series Model 1XSWHH Pressure & Temperature Switch

Brand: United Electric Controls Ltd.

UE's One Series is for tough applications with high cycle rates, severe shock or high vibration.

For plant upgrades, the versatile powering options - Analog loop, discrete input powered (Vdc or Vac) and externally powered models offer options for soft or high capacity SPST alarm, trip or emergency shutdown.

With its integral digital display, the "fit for service" One Series effectively does the job of multiple instruments: transmitter, gauge, process switch, or trip alarm.

The embedded logic and high diagnostic coverage means the One Series is a safer, smarter and less complex device than other sensor alternatives.
Features
  • Transmitter-only, switch-only and hybrid transmitter-switch models offer maximum flexibility
  • Digital process display provides process conditions at a glance
  • Programmable set point and deadband provides the most versatile, accurate and repeatable alarm and shutdown switching
  • Configurable IAW self-diagnostics provide piece of mind that the instrument is functioning properly by communicating with the control system using a dedicated discrete output
  • Plugged Port Detection annunciates a clogged sensor and a closed bypass valve
  • Max/Min memory - samples and stores the highest and lowest extreme process values for process diagnostics and learning
  • Nuisance trip filtering eliminates unwanted nuisance trips and unnecessary alarms
  • Programmable trip delay - hold off the trip decision for tenths of seconds up to several minutes
  • Trip counter - records trips for up to two relays for process diagnostics and learning
