NK-BARRIER Barrier Series Zener Barrier Device Leakage Sensor
Nakamura Electric Manufacturing Co., Ltd.
About This Product
A liquid leakage sensor with an intrinsically safe explosion-proof structure. The 4-stage detection range allows stable detection of everything from 50MΩ impedance liquids to ordinary water. By changing the detection band, it is possible to detect liquid leakage in various environments and usage applications.
■Common precautions regarding Zena Barrier
- Only sensors that have passed the combination test can be used.
・Please store in a non-hazardous location and in a container with IP20 or higher rating.
■Notes
・Wiring/operation/maintenance/inspection work should be carried out by someone with specialized knowledge and skills in the construction of explosion-proof electrical equipment and related laws and regulations.
- When installing in a hazardous location, the hazardous area where it can be installed varies depending on the model, so be sure to check the corresponding hazardous area.
・Specifications/design etc. are subject to change without notice.
