gas industry using QTech

The QTech Wireless Point to Point (WP2P)  has been successfully operating at an industrial site in an environment which has high exposure to toxic substances. Due to the highly corrosive nature of these chemicals it was not feasible to run a control cable around this particular area of the plant. The WP2P is being employed to start a pump which discharges alkaline when the acidity level in large tanks reaches a regulated maximum intensity.

The QTech 900 MHz WP2P, using the supplied stub antenna, provides enough signal strength to ensure reliable pump control despite one module being in an adjacent building. At this site the signal must ‘see’ through a host of industrial steel pipe work, concrete block, fibrous walls and other structures to the receiving module, which activates the pH balancing pump, some 40 metres away in a direct line. If greater distance or stronger signal strength is required higher gain antennas are available from DATRAN Australia.

Key Features of the solution include;

Operational Range: Up to 350m with the supplied antennas, ~2km with optional whip antenna (line of sight)

  • This can be increased further by using a Yagi Directional Antenna or a WP2P Repeater module (environment dependent)
  • Relay outputs – up to 24V/2A
  • State of the art digital radio using 900 MHz digital modulation technology
  • Link Status LED helps diagnostics and confirms a signal path between modules.
