Technical Overview 

This condensation prevention sensor is designed to meet the requirements for a low cost device to provide early warning of condensing conditions. Applications include chilled beam/ceiling systems where control safeguards are required to avoid ‘indoor rain’. The sensor provides either a volt-free contact or current output and is housed in a small enclosure which can be strapped to the surface that requires monitoring.
