Gastech

Our engineers have developed high end electronics and a program that monitors the sensor’s outputs and is tailored to and pre-programmed for many different gas types. The program and electronics process the sensor’s output trends and calculates accurate and stable readings. This is transmitted back to the processor using the industry standard 4-20mA.

Mechanical Design

One card to suit all applications is the philosophy. Many of our customers are in remote locations around the world and holding stock for all the different kinds of detectors and ranges that they have on site
is expensive and difficult to manage. In the C-GuardTM design this card had to be easily configured for the different gasses, ranges, sensors styles and must have enough program memory to hold the logic for
each type of gas. Our engineers were able to achieve all this, with enough resources still available to implement many future features.
Each card will be simple to upgrade as needs change.
Housing is an IP 65 strengthened high impact polymer, which is UV stable and is virtually indestructible. The design of the housing was to meet the most challenging conditions encountered. Grey coloured to blend in with the walls in car park application.

End user Features

• No tool calibration or set up. No screwdrivers, No meters, no special programming tools required to calibrate to comply to AS1668.2
• No alarms during calibration:
  • When in the calibration mode the C-GuardTM 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.
• Zero gas activation test:
  • The C-GuardTM logic has a special activation mode. Once entering this mode the mA output is raised to 12mA for 5 minuets. This allows activation of vent fans or alarms to test the system without wasting expensive test gasses. Again bringing down the total ownership costs.
