Electric Water Leakage Alarm Sensor

  Water Leakage Sensor(Non Locating)     

Product Introduction

Leak sensor is a high performance water leakage detection module, it cooperate with water leakage detection cable or other detection probe, through its relay contact output signal and RS485 communication signal can integrate with various monitoring systems to reach remote alarm and remote control.

Multi-purpose Design

The circuit system use high sensitive components to guarantee high sensitivity and can avoid various mistake alarm caused by outer factors,it also have a unique surge protect design. This module provide independent leakage alarm relay, output normallyopen /normally closealarm signal. Module also havea beeper mutebutton, which can shut down alarm voice according to requirement.

Easy Install/Use

The installation of field wiring canbe easily finished through the pull out plug terminal block in module. The output alarm designed to eliminate leakage automatic reset after water leakage eliminate, the module hasbeeper mute button and detection sensitivity adjustment function. The detection module with small volume is convenient to guide rail or to wall space hang installation.

Wide Application

Detection module is suitable for integration central monitoring system, the typical applications including air handling equipment, refrigeration equipment, liquid container, pump tank or other use sense cable leakage monitoring.

Wiring Instruction

1. Lead-out line and leakage cable plug connection

2. 4 terminals: C, C, RS +, RS -, lead-out line connect to C, Cthis two terminals, to the head of the C, C on the two terminals, both positive and negative, RS +, RS - no connection.

3. 4 terminals:12V,G,NO,C,12V is the power anode , G is power cathode, NO is the normally on end of switch quantity, C is COM end of switch quantity

* Note:Connection terminal specification is 18AWG(1mm2)
