Hauser 33
13 Technical data
13.1 Input
Measured variable • Channel 1
Material moisture in % (variable setting)
• Channel 2
Either conductivity 0 to 20 mS/cm or temperature 0 to 100 °C (32 to 212 °F).
Measuring range • Material moisture
The material moisture can be determined with a water content ranging from 0 to 100 %
• Temperature sensor
The temperature can be determined in the range from 0 to 100 °C (32 to 212 °F)
• Material conductivity
Material conductivity can be determined up to a maximum value of 20 mS/cm
13.2 Output
Analog • Channel 1 (material moisture):
0 to 20 mA/ 4 to 20 mA
• Channel 2 (material conductivity or material temperature):
0 to 20 mA/4 to 20 mA
The analog outputs can be set differently to the following possible options:
Moisture, temperature
Output 1 for moisture, output 2 for material temperature.
Moisture, conductivity
Output 1 for moisture, output 2 for conductivity in the range from 0 to 20 mS/cm
Moisture, temperature/conductivity
Output 1 for moisture, output 2 for material temperature and conductivity with
automatic window changeover.
Starting time
The first stable measured value is present at the analog output after approx. 1 s.
Digital • Serial interface, RS485 standard
• IMP-Bus
• Signal cable and operating voltage are galvanically isolated
• Data transmission rate 9 600 Bit/s
Linearization Up to 15 different calibration curves can be used in the sensor. Linear and non-linear
curves with polynomials of up to degree 5 can be used. The calibration curve can be
selected via the remote display.
