Overview
The microwave level switch determines the capacitance value at the end of the sensor and the dielectric constant value of the medium through a high-frequency electric field. Since the dielectric constant value of air is different from that of the medium, two states can be identified: covered and uncovered. Under normal circumstances, the indicator light is off to indicate uncovered, and the indicator light is always on to indicate covered, and the switch is switched.
This product has the characteristics of compact structure, strong anti-hanging performance, good stability, and wide application of media.
Features
Not affected by foam, can detect foam, and can also penetrate foam to detect liquid under the foam, stable detection.
Can use the handheld operator to set the alarm threshold on site and view the measured value
Can effectively detect adhesive conductive slurry, pure water, metal powder, plastic powder, ultra-fine powder, etc.
