FlexVu® Universal Display (Model UD30)

ATEXCSADet-Tronics Point IR Termination Box (PIRTB) FM ApprovalIECEx

Add standalone capability to a large number of gas sensors and detectors

Designed for use with a large number of Det-Tronics gas detectors, the UD30 is approved as a stand-alone device and can perform functions of a gas controller.

Gas level (%), type and unit of measurement are indicated on the digital display. Access to the local event logs and other display capabilities, such as calibration, is accomplished through four (4) magnetic buttons around the display.


  • Universal design supports multiple Det-Tronics sensors or generic linear 4–20 mA sensors
  • Local digital LCD continuously indicates gas level, gas type and units measured
  • Backlit and heated display
  • Non-intrusive calibration 
  • Rugged construction approved for use in classified hazardous areas
  • Available in 316 stainless steel (shown) and black epoxy aluminum
  • Internal magnetic switches provide a non-intrusive user interface which allows device configuration without declassifying hazardous areas
  • SIL2 models certified to IEC61508 by exida®
  • Logs provided for analysis and management include:
    • Event: Include fault and alarm logs with runtime hours
    • Calibration: With runtime hours
    • Temperature: Two sets of minimum and maximum temperature logs with runtime hours
