• Moisture range in %
• Maximum: e.g. 20 %
• Minimum: 0 %
• Temperature range in °C
• Maximum: 100 °C, this also applies for the high-temperature version.
• Minimum: 0 °C
• Conductivity in mS/cm
• Maximum 20 mS/cm
• Minimum 0 mS/cm
The devices can measure the conductivity depending on the device type and the
moisture. The output is set to 0 to 20 mS/cm at the factory.
8.2
Operating mode
The device configuration is preset at the factory before the device is delivered. This device
setting can then be optimized to suit the process.
Measure mode and parameters:
The following device settings can be changed
• Measure mode C - Cyclic (default setting for devices with cyclic measurement).
• Average time, reaction speed of the measured values
• Calibration (when different materials are used)
• Filter function
• Precision of a single value measurement
Each of these settings is retained even after the device is switched off, i.e. the setting is
saved to the non-volatile memory of the device.
8.2.1
Operating mode
The device is supplied from the factory with the CH mode for applications in the construction
industry, and with the CA mode for general process applications. 6 different operating modes
are available in the C measuring mode, depending on the application.
• CS mode (Cyclic-Successive)
For very short measurement cycles in the seconds range (e.g. 1 to 10 s) without averaging
and without filter functions, and with up to 100 measurements per second internally and a
cycle time of 250 ms at the analog output.
• CA mode (Cyclic Average Filter)
Standard averaging for relatively fast but continuous measurement processes, with simple
filtering and an accuracy of up to 0.1 %. The CA operating mode is also used to record raw
values, without averaging and filtering, to be able to subsequently analyze the measured
data and determine the optimum operating mode.
• CF mode (Cyclic Floating Average with Filter)
Floating average for very slow and continuous measurement processes, with simple filtering
and an accuracy of up to 0.1 %. Suitable for applications on a conveyor belt etc.
