Flat Probe RF Admittance Level Switch For Bulk Material
Working Principle of Flat Probe RF Admittance Level Switch For Bulk Material
Radio frequency admittance level switch, its measurement principle is: radio frequency admittance is a new type of level control technology developed from capacitive, anti-hanging, more reliable, more accurate and more applicable. Level technology upgrade. The so-called radio frequency admittance means the inverse of the impedance in electricity. It is composed of resistive components, capacitive components, and inductive components, and radio frequency is the high-frequency radio spectrum. Therefore, radio frequency admittance can be understood as the use of high frequency. Radio waves measure admittance. When the meter is working, the sensor of the meter forms an admittance value with the filling wall and the measured medium. When the material level changes, the admittance value changes accordingly, and the circuit unit converts the measured admittance value into a level signal output to realize the level measurement.
Design feature of Flat Probe RF Admittance Level Switch For Bulk Material
◎this product uses intelligent microprocessor components and difference measurement technology, which can measure water, sewage, mud and other liquids, especially can effectively and accurately measure strong corrosive media, and can dynamically compensate for environmental changes and hanging materials;
◎the operation is very simple. You only need to adjust the corresponding sensitivity knob according to the medium and use the surge delay filter;
◎ the upper and lower limit alarm modes can be flexibly set, and the user can set and select the normally open and normally closed contacts by himself;
◎High performance imported single pole double throw relays are used for single point and multi-point relays. The single point contact current capacity can reach 8A and the multi-point relay 3A. Can directly drive alarm devices within the range;
◎ PTFE probe is used. There is no movable device at the detection position. It is impact resistant, high-temperature resistant and corrosion-resistant.
