e FlexVu® Model UD20 Universal Display Unit is designed to be used with the GT3000 Toxic Gas Detector.
It is recommended for applications where a 2-wire loop powered gas detector is required. The output is a 4-20 mA signal with HART, corresponding to the output of the GT3000 detector.
Gas concentrations are displayed on an alpha-numeric display in ppm (% for O2). The display unit reads the linear 4-20 mA DC output signal from the GT3000 that corresponds to the detected gas concentration. The UD20 automatically detects the gas type and operating range of the sensor to which it is connected via the HART signal.
