  • Fluid Temperature: -40°C ... 130°C

Application description

The SLK rod probes are used in conjunction with the evaluation units (eg, SRA-100-U0) for level detection and level control in conductive liquids, especially in food and used in the pharmaceutical sector, where high hygiene requirements.

Depending on the number of bars and evaluation devices used, different measurement tasks such as Overflow, dry run, two-step control, moisture detection, etc. are realized.


Depending on model selected can include the container wall as a mass, to be implemented to 4 set points. The ground connection is made in the probe head and is transferred through the threads on the conductive container.

Process connections, various hygienic connections are available, the seal gap, flush.


In the probe head, an additional module (diode module LBM) for permanent circuit monitoring to be installed.

In the case of a line break between the electrode probe and an appropriate evaluation, the evaluation issue an alert.


By stainless steel process connection the probe is to 20bar pressure stable and in conjunction with the ETFE coating, process temperatures up to +130°C can be realized.
