Level alarm Afriso VA-SIGNAL W Wireless 12V DC with 2m sensor cable

Full tank alarm for sewage tanks

VA-SIGNAL W is a full tank alarm for closed sewage tanks. The device is based on alternating current technology, which minimises the risk of corrosion on the sensor electrodes. The alarm has a very safe function as it has no moving parts. The conductive alarm is intended for wastewater or other electrically conductive liquids. The alarm is triggered when both electrodes of the sensor are surrounded by the liquid. Communication between the alarm unit and the sensor is wireless via LoRa on the 433 MHz band. The transmitter unit is powered by 1 ER14505M Lithium battery (3.6V) with an expected life of more than one year. When the battery starts to get low, a signal is emitted on the receiver unit. Built-in relay for external alarm output with a closing potential-free output for connection of alarm lamp, external alarm etc.
