1.2.2 Temperature monitoring

The temperature is monitored by a temperature sensor (Pt100) located in the
medium and protected by a protective pipe. Depending on the version, switching
outputs combined with an analog output (4 - 20 mA) or digital output (IO-Link) are
available. The display options can show the temperature on the display and output it
on the analog output. The sensor options offer the possibility of an analog output of
the temperature.
Please observe the technical data in the appendix.

1.2.3 IO-Link

If an IO-Link interface is available at the sensor, it is possible
to access identification, process and diagnosis data. Sensor parameters such as
switching points or switch-back points can be set during operation. Prerequisite for
this is an IO-Link master with the corresponding configuration tools.
When replacing the sensor, all parameters already set can be transferred to the new
sensor.
The sensor includes an electronic device description, the so-called IODD file. The
IODD file contains all the information required for system integration. The file can
be downloaded from the download area at https://ioddfinder.io-link.com.

1.3 Construction types

The WGM is available in three basic types:
Type Description
WGM-B Basic option - Sensor only
WGM-D Display option - Sensor with display
WGM-R Remote display for basic option
(connection only possible to basic option WGM-B-1X/2A1S-G34-V)
Depending on the configuration, the WGM is equipped with different switching and
analog outputs. The outputs are freely programmable.
The sensor options are available with a digital interface. Here, the sensor uses the
standardized technology IO-Link, a powerful point-to-point communication. It is
based on the previous and proven connection technology. Compatibility with the
previous technology is guaranteed.
