Independant Leak Sensing Probe
SUMMARY
The Microprocessor Controlled miniature BMS single zone alarm detects leaks when conductive fluids touch and bridge both conductors at its sensor.
The internal processor analyses the conductivity of the fluid before it onward signals the sample as a leak.
On detection of a fluid, the green LED changes to red and the internal Alarm relay energises and its contacts change state.
monitoring
The conductors must be kept clean and away from conductive materials to prevent spurious alarming
The system has a sensitivity adjustment to trim out excessively sensitive areas.
Installation
The BMS alarm can be installed in the area susceptible to leaks.
A regulated supply of 9v to 24v DC connects positive to the +v and negative to the -V terminal.
The sensor connected should be firmly laid to the areas the system is monitoring
The conductors must be kept clean and away from conductive materials to prevent spurious alarming
The system has a sensitivity adjustment to trim out excessively sensitive areas.
