NYDR radio frequency capacitance switch is a highly intelligent liquid level measurement product, which overcomes the inconvenience caused to customers by the low alarm accuracy and complicated adjustment steps of the previous measurement methods. Radio frequency capacitance switch is widely used in chemical, metallurgy, petroleum, machinery, food, food materials and other industries.
How it works NYDR capacitance level switch adopts advanced digital intelligent compensation technology to convert the change of liquid level in the container into the change of capacitance. There are two plates in the probe. The change of medium changes the dielectric constant between the electrodes, thereby obtaining the change of capacitance. The capacitance is converted into a pulse digital signal through the electronic plug-in, and the alarm point design and alarm action are realized through the microprocessor. Design Principle This product uses intelligent microprocessor components and differential measurement technology, which can measure water, sewage, mud, and other liquids. In particular, it can effectively and accurately measure highly corrosive media, and can dynamically compensate for environmental changes and hanging materials. This product can be used to build in auxiliary electrodes in non-metallic tank sensors, and no additional electrodes are needed in the container; The operation is very simple. You only need to adjust the sensitivity knob and surge delay filter according to the medium. The upper and lower limit alarm modes can be flexibly set, and users can set and select normally open or normally closed contacts; Both single-point and multi-point relays use high-performance imported single-pole double-throw relays. The current capacity of single-point contacts can reach 8A, and that of multi-point contacts can reach 3A. They can directly drive alarm devices within the range; Adopt polytetrafluoroethylene probe, no movable parts in the detection part, impact resistance, high temperature resistance and corrosion resistance.
