Simple Operation RF Capacitor Switch Used For Highly Corrosive Media
Working Principle of RF Capacitor Switch
The sensor works based on the principle of component vibration, and the component part is the tuning fork part immersed in the measured liquid. The tuning fork part induces vibration through a piezoelectric device fixed at one end of the bottom of the fork body. The oscillation frequency is detected by a secondary piezoelectric device fixed to the other end of the fork, and then the signal is amplified by the circuit on the top. The liquid density is closely related to the vibration frequency when the measured liquid flows. When the measured liquid density changes, the vibration frequency when the liquid flows also changes. Through the equation, the density of the measured liquid can be accurately calculated
Design feature of RF Capacitor Switch
◎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.
