Universal Moisture Measuring Sensor

Moisture measuring sensor with measured-value transfer by standard signal (e.g. 4…20mA or 0..10V).

Capacitive moisture sensor for detecting the water content of bulk solids like: biomass, sawdust, woodchips, cocoa, coffee, grain, corn, gypsum, sand, concrete, slag sand, sludge, waste glass and many more.

This universal usable moisture measuring sensor has an analogue measuring arrangement and uses the capacitive measuring principle for determining the moisture content of material. By standardized analogue signals (e.g.4...20mA, 0...20mA or 0...10V) the measure values are delivered to a PLC or a controller. The calibration of the sensor has to be done by rotary potentiometer, beyond the actual process.
