Failsafe Design Liquid Leak Sensor

For the advanced performance is added to Standard Liquid Leak Sensor, RS-2000 series has self diagnostic function for alarming the electric failure or wiring error by short circuit or cut circuit, as realizing ‘Failsafe’ property to the system.

RS-2000 Series

・RS-2000 detects liquid leak, also breaking of wire and short circuit. Then alarm.
・RS-2000 can provide superior safety system than RS-1000 by this diagnostic function.
