Water damage can be avoided

April 2010 Analytical Instrumentation & Environmental Monitoring

The Afriso-Euro-Index WM5 water alarm unit monitors up to five independent points for water. The unit can be used, for example, in IT, office and storage rooms, industrial facilities and basements. If one or several probes are submerged in liquid, the control unit detects the change in the probe signal and generates visual and audible alarms.

A three-core cable is used for connection to the control unit, which contains the following elements in an impact-resistant plastic housing:

* Display elements and controls.

* Electronic components for signal processing and conversion of the analog probe input signal into a digital output.

* A voltage-free relay contact (changeover).

The probes are mounted at the lowest point of the area to be monitored. If the unit detects water, it immediately generates visual and audible alarms. The unit indicates which of the probes (1-5) generated the alarm, and a mute control is included for silencing the audible warning.

The control unit is supplied from 230 V a.c., and is designed for easy wall-mounting or installation in control cabinets or panels. Optional mounting frames can be supplied on request. In order to ensure maximum reliability, particularly in IT or process technology facilities, AFRISO event reporting systems can be connected to the water alarm. The operator is then immediately informed of alarms via either the Internet, e-mail, SMS, telephone or fax to enable fast and efficient reaction.
