In the use of the site, what are the coal plug switches
1, according to the measurement needs of the field, the use of more resistance spin material level switch, it has the advantage of low cost, in the particle, powder, block medium, has the characteristics of high stability of measurement.
2, radio frequency admittance level switch, this is a relatively high cost of material level sensor, high measurement sensitivity, and has the characteristics of preventing hanging material.
3, intelligent display type rf capacitive material level controller, compared with the former two kinds of material level sensor, its use cost and promoted a step, but its performance is better, not only for liquid and solid material level measurement with high precision, and can also be measured ultra low dielectric constant of the medium, such as: typical cooking oil, plastic particles, etc.
In the measurement of raw coal condition, rf admittance switch is the most used.
