radar level gaugeIt is a measuring instrument based on the principle of time travel. Radar waves travel at the speed of light, and the travel time can be converted into level signals through electronic components. The probe emits high-frequency pulses and propagates along the cable. When the pulses encounter the surface of the material, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.
The measurement principle of radar level gauge is the same as that of radar level gauge and radar water level gauge, except that their measurement media and application environments are different.
radar level gaugeCommon troubleshooting methods
1. The on-site meter head of the radar level gauge displays 0.04m, while the main control computer displays 1.8m, indicating that the on-site display does not match the computer display and the difference is too far.
If the output percentage does not correspond to (displayed value/range) through the output indicator bar on the field header, it indicates that the maximum range (maxscale046) is consistent with the full tank calibration (FullCalibr. 006). Modify this parameter to make it consistent.
2. Measuring the material level too low or too high (not in line with the operator's habits, the measurement is still accurate)
By changing the value in the offset 057 menu of the radar level gauge, if it shows a high value, adjust the value to a lower value; if it shows a low value, adjust the value to a higher value.
3. The material level displayed decreased during the cutting process, but after stopping the feeding, the material level was detected to be correct.
The installation position and projection angle adjustment of the radar level gauge are not ideal. The falling raw materials during the feeding process affect the radar echo, but result in incorrect sensor measurements. Solution: Adjust the projection angle of the horn mouth so that the projection line of the horn mouth intersects with the trajectory of the cutting. Angle adjustment requires multiple adjustment tests.
