AMALGAMATED Instrument Co (AIC) has announced the availability of a rain/precipitation detection and alarm system and a flood/liquid detection and alarm system.

The systems consist of a detection and alarm module and a specialised sensor for each function.

The base detection module is powered by 24V dc or 24V ac and provides two changeover relays for alarm functions. An automatic timer function minimises the likelihood of nuisance alarms as the input must be present for 10 seconds before the relays will activate.

The rain/precipitation sensor head has a printed circuit sensor surface and is also fitted with a heater. The heater is designed to speed the return to a "no precipitation" condition and to help eliminate false alarms due to dew or fog condensation.

The flood/liquid sensor has two stainless steel probes and the impedance between the probes to an ac signal is monitored. Multiple sensor heads can be attached to one detection module to provide a wide area coverage.

Both sensor heads are supplied in IP65 enclosures and the monitor is supplied as a DIN rail mount module.

The liquid/flood detection system is suitable for HVAC, under floor wiring, computer rooms, laundry applications, or other situations where the presence of free water could be a safety hazard, or is a symptom of a system failure.

The rain/precipitation detection system could be used to control the activation of automatic roofs or to shut down sensitive processes.
