AMMS

Compact Moisture Measuring Sensor

Category:

Description

Overview

The AMMS sensor combines the advantages of calibration in the process with a direct measured-value transfer (e.g. 4…20mA) brought together in a compact version

  1. Compact but complete
  2. Just a sensor! No evaluation unit necessary
  3. Calibration within the process
  4. Sensor adjustment while already installed
  5. Direct output module
  6. Analogue standard signal (e.g. 4…20mA) directly from the sensor
  7. Multi-point calibration
  8. For even better measuring results
Properties:
  • Capacitive moisture measurement
  • Temperature range of measuring material 4…70°C
  • Electronic temperature compensation
  • Direct measured-values transfer from the sensor
  • Multi-point calibration
  • Integrated averaging
  • Comfortable, clear calibration software, optional
  • Alternative: “direct“ calibration without software possible
Versions:
  • Integrated temperature sensing device (Pt100) optional
  • Several analogue standard signals like 4…20mA / 0…20mA / 0…10V
  • Sensor for measurement in a silo
  • Sensor for measurement in a mixer

The AMMS sensor with its integrated microprocessor establishes a transition between the DMMS system and the analogue moisture measuring sensor MMS.

Beside a power supply this sensor only needs a display or a PLC which is waiting for its measuring value. The AMMS sensor has been designed for applications which do not need a multi-pieced system but benefit of a precise on-line calibration that is able to compensate the influences of the installation. It’s also possible to calibrate the AMMS sensor directly by an integrated rotary encoder. This work actually takes place before the sensor has been installed.
