ZY-SPDN-LWJ RF admittance level gauge

1、 Overview of RF admittance level meter
ZY-SPDN-LWJ RF admittance level meter is a level instrument developed in collaboration with Sanxiong Company in the United States. The instrument adopts the principle of radio frequency admittance measurement for level measurement, and its shielding technology solves the drift and misoperation caused by probe hanging and temperature and pressure changes in working conditions. The instrument works stably and reliably.
The URF type radio frequency admittance level meter consists of a probe, electronic unit, and protective housing, and can be installed as a whole or separately. It has significant characteristics of high sensitivity, good stability, and is not affected by hanging materials, and can be used for limit control of various liquids, slurries, solid particles, or powders. Its output is a double pole double throw relay contact signal.
2、 ZY-SPDN-LWJ RF Admittance Level Gauge Product Features
Maintenance free: No mechanical wear parts, no need for regular maintenance or replacement
Anti hanging material: The design of shielding technology in circuits allows instruments to ignore the impact of probe hanging material, without the need for regular cleaning or repeated calibration
Widely applicable: capable of measuring liquids, slurries, solid particles, and powders
Easy installation: It can be installed through the threaded mouth or flange on the tank, and can be installed as a whole or in parts. Debugging is simple and convenient
