Biral adds test functionality to range of visibility and present weather sensors

Sensor manufacturer Biral has announced that it has added a new test function to its entire range of visibility and present weather sensors. All of the Biral sensors are now supplied with enhanced internal software featuring a new test setting that 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 enables 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. The sensors that have been fitted with the new functionality include SWS, RWS and VPF visibility and present weather sensors. 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.
