GasTech Australia's latest series of gas detectors: The Digital Guard (D-GuardTM). This new style of gas detector uses an advanced processor and program logic, making the choice of a reliable detector simple.
Our engineers have developed high end electronics and a program that monitors the sensor’s outputs and is tailored to and pre-programmed to many different gas types. The program and electronics process the sensor’s output trends and calculates accurate and stable readings which are displayed on the permanently backlit graphic display. This is transmitted back to the processor using the industry standard 4-20mA.
Housing is a IP 66 carbon filled anti static Nylon, which is UV stable. The design of the housing was designed to meet the most challenging conditions encountered in off shore oil rigs.
No tool calibration or set up.
This is probably one of the most useful features of this system. Once you open the calibration door the D-Guard locks the output signal at zero gas reading until the calibration process is finished. Our engineers have implemented a fail-safe logic to maintain constant monitoring. There is also an isolate switch, which will permanently isolate all signals and alarms until the operator reactivates the unit.
