product overview

DC seriesSwitching RF admittance level meterSuitable for measuring the position height of liquids and solids, it provides DPDT contact output and is not affected by material adhesion and probe. This product uses radio frequency signals of appropriate frequencies and detects capacitors, resistors, and inductors, eliminating errors such as virtual object positions that cannot be avoided by capacitive technology, and has multiple different forms. Suitable for measurement in high-temperature vibration, stirring, or confined spaces. In order to overcome the influence of attachments, an additional protective electrode is added between the main electrode and the ground electrode of the admittance level switch to ensure the correct signal level. This special electrode structure is particularly suitable for detecting various materials and is not affected by material adhesion. Due to the protective effect of the electrode, only the RF current changes passing between the main electrode and the barrel wall will be detected by the circuit. Therefore, when the probe comes into contact with the material, an accurate signal level will be generated, which is proportional to the dielectric constant but inversely proportional to the resistance value. This signal is easily detected by the circuit and outputs a control signal.

Product Features

Strong universality: widely used in various occasions, including fly ash, particles, powders, liquids, viscous, conductive, and non-conductive materials;
Anti adhesion: The unique circuit design allows the measurement circuit to ignore the accumulated materials on the probe and automatically correct them;
Powerful function: Large output contact capacity and status indicator light to display working status, with a delay of 0-30 seconds to eliminate the impact of material fluctuations;
Power outage protection: normally open or normally closed (can be switched on-site).
