The central salt and marine chemicals research institute (CSMCRI) has developed an optical liquid switch is useful for detection of either absence or presence of water (clear or turbid) or detect water level. Optical liquid switch is suited for use in any process directory employing water service. The change in state from presence to absence of water or vice-a-versa, triggers inbuilt relay (250Vac/220Vdc @ 2A) which can be used for switching applications and/or for annunciating audio or visual alarm, or signaling process controllers.
Some of the switch’s applications are Over-flow detection in tanks/reservoirs/pans/ dams, low-level or high-level monitoring with warning/control in tanks, salt farms, empty pipe/blockage detection in water/ drainage pipelines, water level warning on vehicles, alarm in events of water flow over bridge/road or under-pass for traffic management and safety, water-level monitoring and alarm in open canal/stream/open drainage for vicinal population safety, warning of high tides in coastal areas, telecom outdoor stations, electrical substation, tunnels, basements for rainwater ingress alarm and domestic appliances based on water application.
Owing to growing awareness for water conservation, OLS market is huge and it is cost effective for deployment. It’s features include, low cost, low power demand, compact design, no calibration/adjustment required, pipe end-connection, water proof, easy installation, suitable for various applications.
