Liquid Leak Sensos Special Feature

Liquid Leak Sensos Special Feature

Introduction

Leaks from pipes, condensation, and flooding can cause damage to equipment and facilities, while hazardous chemical leaks pose risks of accidents and disasters. Such environments are not uncommon in various industries. The role of a liquid leak sensor is to quickly detect these dangers and prevent them before they occur.

Our WL10 series liquid leakage sensor is an optical spot-type sensor utilizing infrared reflection. The detection mechanism consists of a light-emitting diode (LED) and a photodiode (PD) inside the sensor. Light emitted from the LED is reflected by a prism and received by the PD, where it is converted into an electrical current. When liquid comes into contact with the prism, the light transmits through the liquid, significantly reducing the amount of light reaching the PD. This phenomenon is used to detect leaks.

3. No Need for a Shade-plateWithout Non Shade-plate

Typical leak sensor

WL10

In environments with strong ambient light, such as mirror-finished floors, conventional leak sensors may fail due to excessive light received by the PD. However, our WL10 utilizes unique advanced optical technologies to minimize the effects of diffuse reflection, significantly reducing location constraints.

Typically, a "shade plate" is used beneath leak detection sensors to control excessive light interference. However, the WL10 does not require this, eliminating the risk of undetected leaks caused by liquid surface tension preventing it from passing over the plate.

4. Without an external AmplifierAmp.

No amplifier is required, so ready to use. Under normal conditions, the switch output remains ON, and the LED lights up green. When a leak is detected, the switch output turns OFF, and the LED changes to red.

5. High Sensitivity & Fast Response

Detects leaks instantly. Check out the video bellow to see the high performance of the WL10.

6. PFA casing model available

Suitable for use with water and other corrosive liquid media.

7. IP67 structure

Waterproof and Dustproof with IP67.

8. RoHS compliant, UL and UL, CE certified

RoHS compliant, cULus recognized and CE marking certified.
