Test Function Added to Biral's Weather Sensors

|

Meteorological specialist Biral said it has added a test function to its entire range of visibility and present weather sensors.

All of these Biral sensors are now supplied with enhanced internal software featuring a new test setting which can be used as part of Factory or Site Acceptance Testing (FAT or SAT) at client handover.

With this feature, the sensors can now be switched into a 'test mode' via the serial PC connection. This test mode allows the user to force the sensor to report user-defined data for visibility, present weather, window contamination and fault status for a fixed period of time.

This new feature is designed to allow users to test the operation of other connected equipment such as aviation or marine warning lights or signs which are configured to operate at specific visibility conditions. In this way, the end-to-end control system operation can be demonstrated and tested for both commissioning as well as client acceptance approvals.

There are three ranges of Biral equipment which now come with this enhanced capability and these are the SWS, RWS and VPF visibility and present weather sensors which are used in applications from climate research to highway, aviation and navigational safety.

All sensor models use forward scatter meter technology to measure present weather and output Meteorological Optical Range. There are five models in the SWS range and four models in the VPF range, covering a host of applications from roads, tunnels and weather networks to the harsher conditions of marine and aviation.
