JS - DW is mainly used in monitoring if somewhere is immersed in water.It can detect water at anywhere of cable. Once detected cable leak somewhere, it locate the flooding and immediately alarming.(LED indicator alarm and relay output alarm ), then display the flooding position on the LCD. Its working principle is monitoring and sampling the current signal of the water immersion cable,then the transmitter's special MCU amplified the sampled signal, calculation and analysis to get the immersion locate information.
Widely used in the underlying data center floor, telecommunications room, hvac equipment, pipeline, power room, storage areas, large sink and the occasion need to be detected such as roof and tank which is leakage and so on.
Water immersion cable is small and light, strong flexibility, easy to installation.
Double power supply: alarming device power supply mode can be chosen by the user for DC 24 V( 22.5 V ~27 V))
LCD display and key input: a LCD display module can directly show the information of immersed location and communication parameters displayed.It can convenient to set equipment parameters by the external key
Alarm output: by LED alarm output and relay alarm output
Communication parameter setup: when multiple devices at the same time online, communication parameters (port and baud rate) can be setting through key
Data remote transmission: provide communication standard interface RS - 485 , remote transmitte the immersion location information, the maximum transmission distance is 1000 m, at the same time guarantee the commonality of newsletter way
Good isolation, power, input, output, three-terminal isolation technology, greatly improve the electrical compatibility and system reliability; Output of the photoelectric isolation and coil isolation protection, effectively guarantee product's reliability and extend the life
Using features: water immersion cable installs hug ground, no direction of polarity requirements, anti-oxidation, prevent polarization, anti-corrosion design
