UOTEK Water Immersion Sensor

Model： UT-5535

● Adopts a waterproof shell

● With a high protection level

● Suitable for long-term use in humid, high-dust, and harsh environments.

Water immersion sensor is widely used in communication base stations, hotels, restaurants, data centers, libraries, archives, warehouses, equipment, cabinets, and other places where water alarm is needed. It adopts unique AC detection technology, effectively avoiding the problem of decreased water leakage sensitivity due to the long-term oxidation of the water immersion electrode. The RS-485 output follows the standard Modbus-RTU, with a maximum communication distance of 2000 meters. It can be directly connected to PLCs, industrial control instruments, HMI, or SCADA software on-site. The external leak electrode can reach up to 2600 meters, and a leak rope up to 2600 meters can also be connected. The device adopts a waterproof shell, with a high protection level, suitable for long-term use in humid, high-dust, and harsh environments.
