Radio frequency admittance level switch
Can detect all the material and not affected by material density, particle size, chemical composition, precipitation viscosity and the effects of parameters such as conductive characteristics. Radio frequency admittance level switch widely used in liquid, powder, paste, solid and so on the many kinds of material control. Radio frequency admittance level switch introducing American high-tech Nu Ⅱ - KoTe (anti adhesion) circuit, make the probe has resistance to all kinds of material (including conduction or insulation) assemblages adhesion function, radio frequency admittance level switch can detection with one of the all kinds of material (high) and (low). Radio frequency admittance level switch sensor probe choose high quality stainless steel and the United States TEFLON materials manufacturing, used in high temperature and high pressure and corrosive material occasion.

Radio frequency admittance level switch
Also called radio frequency admittance material level switch and material level controller, it is widely used in the liquid, the slip body, solid and so on the many kinds of material control. HLRF100 type radio frequency admittance level switch (material level switch) is our company introduces the American high-tech Nu Ⅱ - KoTe (anti adhesion) circuit, make its sensing probe has resistance to all kinds of material (including conduction or insulation) assemblages adhesion function, so that the probe does not produce false signal and error signals, and at the same time can be all kinds of resistance the impact of fluctuations. Can detect containers of various materials (high) and (low). It set up high or status model of fault alarm, with failure insurance function. Sensor probe choose high quality stainless steel and PTFE material manufacturing, used in high temperature and high pressure and corrosive material occasion.
Radio frequency admittance level switch principle
Radio frequency admittance level control technology is a kind of capacitive level control technology to be developed, prevent hanging (sensor adhesive material called a hanging) performance better, more reliable, more accurate measurement, usability broader level control technology, "radio frequency admittance" in "radio" not only high frequency, "admittance" meaning for electrical impedance in the bottom, it consists of impedance ingredients, capacitive component, the perceptual component integrated and become, so radio frequency admittance technology can be understood as using high frequency signal measuring admittance method.
