2.0Mpa RF Admittance Level Switch With Power Loss Protection
Working Principle of 2.0Mpa RF Admittance Level Switch With Power Loss Protection
The probe of the RF admittance switch emits a signal. The RF admittance switch uses high-frequency technology when working. It will send a signal to the probe on an electronic circuit. At this time, the probe will report the movement of the material level to the electronic circuit at any time. The movement includes the occurrence of The capacity of electricity and the amount of electricity derived are data that change at any time, and the electronic circuit processes and analyzes these signals at any time. The high frequency receives the electronic circuit signal and makes predictions. The change of the signal at any time will cause the phase change of the high-frequency signal, which affects the difference between the high-frequency signal and the electronic circuit signal. This difference also changes at any time during the continuous use of the material. This change is compared with each other. After that, if the difference is too small, it means that the material is about to bottom out, and then the alarm system will give an alarm in time to request to add material. On the contrary, it means that there are still materials in the material bin.
Design feature of 2.0Mpa RF Admittance Level Switch With Power Loss Protection
◎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.
