Family	Digital Moisture Meauring System	Moisture Measuring Sensor	Universal Moisture Measuring Sensor
Physically measuring principle	capacitive	capacitive	capacitive
Description	Digital moisture measuring system with up to 16 sensors per evaluation unit. Switching material curve for each sensor. Wiring becomes easy by using bus-technology. Transfer of the measuring values by Profibus DP or by analogue signal. Calibration is done comfortable per software.	Compact sensor with fully digital measurement technology, controlled by microprocessor. No separate evaluation unit needed. Analogue output signal, 4...20mA, direct from sensor. Calibration is done per intuitively operable software.	Moisture measuring sensor with analogue measuring arrangement. Analoue output signals (4...20mA, 0...20mA or 0...10V). Calibration of the sensor has to be done by rotary potentionmeter, beyong the actual process.
