Working principle
High temperature material level switch work principle is based on radio frequency (RF) capacitance technology, will be a radio frequency on the probe, through the continuous analysis, to determine the impact of the surrounding environment. For all the material contact due to the small capacitance shift reflects the total impedance change. Because live probe and vessel wall constitute a capacitor of two pieces of plate, probe of insulator and the surrounding air become dielectric material, when air (its dielectric constant is 1.0) by any other materials (dielectric constant > 1) replacement, capacitance effect to strengthen. Which changed the impedance of the applications. Namely capacitance value change caused the change of impedance. This influence is circuit measurement after another, and the sensitivity Settings (circuit) resume reference datum phase comparison.
Product description
FYGS high temperature material level switch is Beijing ginde venture measurement and control technology co., LTD. In the radio frequency admittance level switch on the basis of the research and development of products.
FYGS high temperature material level switch with an adhesive circuit design, and detects real physical position at the same time, eliminate the adhesion and suspension in the probe around the false level signal influence.
