Introduction
principle
The radio frequency admittance level switch is composed of a sensor unit and an electronic unit. The sensor unit mainly includes three parts: the measuring probe, the shielding electrode and the ground terminal. The height of the material is reflected as the change of the admittance between the probe and the container wall. When the material reaches the switch operating point, the electronic unit responds and drives the relay to act. Output switch signal. The shielding pole can prevent the malfunction signal due to the material hanging on the electrode, and the switch control signal is output only when the material really reaches the set point.
application
It is widely used in the alarm and control of liquid, slurry, dust, material level and two liquid interface levels.
Features
The radio frequency admittance level switch adopts advanced radio frequency admittance technology, which overcomes the defect that the capacitive level switch cannot eliminate the influence of conductive hanging material. The instrument operates reliably, and various technical indicators have reached the international level of similar products. In addition, the product has added on-site working status indication, which is a very stable and reliable level switch with high performance and price ratio.
