Water Leakage Detector FS20702 Introduction

Water Leakage Detector FS20702 is equipped with a waterproof shell with a high protection level, which can be used for a long time in harsh environments such as humidity and high dust. It is widely used in communication base stations, hotels, restaurants, computer rooms, libraries, archives, warehouses, equipment cabinets, and other places where water immersion alarms are required.

The sensor uses unique AC detection technology and does not rely on special electrodes, effectively avoiding the problem of decreased water leakage sensitivity caused by the oxidation of the immersed electrode during long-term operation. It has a long service life and reliable detection. The output mode can be selected as Modbus-485 or switch quantity, which is convenient for customers to use.
