Product Description

RF Admittance Level Switch with more advanced technology to replace capacitive RF admittance measurement, adhesion of materials to solve the problem, compared to other similar products with higher system stability, even in extreme field conditions, it can work reliably, and are not linked to material, temperature, pressure, density, humidity, and even the impact of changes in chemical properties of materials, performance, reliable, widely used for ash, mortar, cement clinker, coal and other media level measurement.

Measurable level and material level, to meet the different temperature, pressure, media measurement requirements.
Linked material impact from the sensor, without regular cleaning, to avoid incorrect measurements.
Measurement with no moving parts, no mechanical parts damage problems.
No maintenance, intelligence-free transfer.
Contact measurement, anti-interference ability, can overcome the steam, foam, and mixing on the measurement of the impact...
Measuring the amount of diversity, so that more accurate measurement, the measurement from environmental change, high stability.
Products are reliable, long service life.

RF Admittance Level Switch the RF admittance level meter [2], RF Admittance Level meter potentiometer sensitivity adjustment potentiometer W1 as: LED color display lights green light in the absence of material state, material state with red light. Instrument is powered, the material level is below the set value, the green light, then slowly adjust the potentiometer clockwise W1 to just the red light, then 3 turns counterclockwise adjustment (0.5 for non-conductive materials, 3 laps, conductive material 5 7 laps) and green light (with lights display the status of the output relay contacts change state should also be changed). Should be based on measurements of different parts of the media sensor cover materials should be about 75mm.
