3、 Working principle of flour level gauge manufacturer:

Flour level gauge manufacturers are a new type of level control technology that has developed from capacitive technology, with anti hanging materials, greater reliability, accuracy, and wider applicability. It is an upgrade of capacitive level technology. The so-called radio frequency admittance refers to the reciprocal of impedance in electricity, which is composed of resistive, capacitive, and inductive components. Radio frequency refers to the high-frequency radio spectrum, so flour level gauge manufacturers can understand it as measuring admittance using high-frequency radio waves. When the instrument is working, the sensor of the instrument forms an admittance value with the tank wall and the measured medium. When the level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into a level signal output to achieve level measurement. The radio frequency admittance level gauge consists of a sensor and a control instrument. The pulse card in the sensor can convert the level change into a pulse signal and send it to the control instrument. After calculation and processing, the control instrument converts it into an engineering quantity display, thus achieving continuous measurement of the level. Due to the use of radio frequency admittance detection technology, reliability has been improved and installation and debugging have become very simple.

The important difference between flour level gauge manufacturers and capacitive technology lies in the diversity of measurement quantities and anti hanging material technology. The diversification of measurement quantities by flour level gauge manufacturers lies not only in measuring capacitance, but also in measuring the comprehensive quantity of capacitance, resistance, and inductance, making the measurement more comprehensive and accurate.

Anti hanging material technology involves adding a shielding electrode between the measuring electrode and the electrode to protect the measuring electrode from hanging materials. A wire is drawn out from the measurement signal of the circuit unit, amplified by a in-phase amplifier, and its output is connected to the shielding layer of the coaxial cable, and then connected to the shielding layer of the probe. This amplifier is a in-phase amplifier with a gain of "1". The output signal is at the same potential, phase, and frequency as the input signal, but isolated from each other. The ground wire is another independent conductor in the cable. Due to the above-mentioned relationship between the centerline and outer shielding of coaxial cables, there is no potential difference between the two, so no current flows through, that is, no current leaks out from the centerline, which is equivalent to no capacitance or capacitance equal to zero between the two. Therefore, the temperature effect of the cable and the installation of capacitors will not have any impact.

Fast calibration method for flour RF admittance level gauge
1. Connect the probe and meter head correctly, and connect the power supply. Pay attention to whether the power supply voltage is correct. Preheat for 3 minutes.
2. The three potentiometers on the dashboard can be adjusted within the range of 8 o'clock to 4 o'clock, and cannot be rotated 360 degrees, otherwise the potentiometers will be damaged. Green light represents normal status, red light represents alarm status.
3. Potentiometer F represents fine adjustment (abbreviated as F); Potentiometer C represents coarse adjustment (abbreviated as C); Potentiometer DLY represents delayed output (abbreviated as DLY): delay time 0-30 seconds), which can be set or turned off arbitrarily.
4. In general, place the FALLSAFE plug in the L position and turn off the delay (rotate counterclockwise to the end).
5. Place F at the 2 o'clock position, adjust C, and turn it to the critical point around the 10-2 o'clock position (first turn the green light clockwise to the red light, and then turn the red light counterclockwise to the green light position). This position is called the monitoring point. If it is already a red light after power on, adjust C counterclockwise. When the red light turns green, it is the critical point.
6. Adjust F clockwise again to find a more critical point. At this time, a green light status should be displayed.
7. If it is applied to the powder ash system, rotate F counterclockwise by about 20 degrees from the critical point position.
