Type in the SBS is the connecting cable already connected and encapsulated in the probe head. Through this encapsulation, the probe is outside of the container completely submersible.

The cable electrode SHT is primarily used as a submersible sensor in conjunction with appropriate evaluation devices (eg, SRA-100-U0) for limit detection and level control in conductive liquids.

The switch point is given by the length of the connecting cable, thus a simple switching point adjustment possible. With the 2-pole version no additional mass probe is required.

The filling level limit switch KAK resp. KLK is used, to evaluate one or two filling levels resp. limit levels in electrically conductive liquids with a conductivity of minimum 5µS/cm resp. a resistance of maximum 200kOhm. The device is also useable as overflow protection in container with liquids, for the realization of a two-position-control e.g. for pump control or also as dry run protection.

The conductivity also of aggressive filling liquids can be detected, at process temperatures from -40 °C to +100 °C, at pressures from -1 bar to +10 bar.

The version KAK is the standard type for general applications, whereas the version KLK is especially conceived for food applications.>

The leakage probes of the series PUK / PUKK are used in conjunction with a suitable evaluation for conductive leakage monitoring of electrically conductive products. The leak detector is designed for a wide range of applications. The conductivity, even of aggressive contents, from 1 μS/cm are recorded at process temperatures from -20 ° C to +60 ° C.

An additional module (diode module LBM) for line monitoring in the housing can be installed in the device. In the event of a line break between the leak probe and a suitable evaluation the evaluation may issue an alert.

Once the electrically conductive filling material forms a connection between the electrodes, a measurable current is flowing, which causes a reaction of the connected evaluation unit. By the use of an AC voltage the corrosion of the electrode and the electrolytic decomposition of the contents is avoided.

The probe relay (Ex) SRA-100-U0 works in conjunction with conductive probes, as a level limit switch or control in conductive liquids such as water, alkalis and acids. A functional extra-low voltage according to VDE 0100 Part 410 of approx. 9V is applied to the electrodes, which means that touching the probes is completely harmless.

As soon as the electrically conductive filling material forms a connection between ground and e.g. the maximum electrode, a small alternating current flows, which is converted into a relay output in the evaluation electronics.

In the case of metallic containers, the container wall can be used as the mass, or an electrode in the case of non-metallic containers. The use of alternating voltage prevents corrosion on the probe rods and electrolytic decomposition of the product. The device can work with relay locking or minimum and maximum switching points, as well as a double limit level indicator with two separate outputs.

This enables a variety of measurement tasks, such as overflow, dry run protection, two-point control, moisture detection, etc. to be implemented. The sensitivity to the conductivity of the liquid can be adjusted via a coarse and fine adjustment. With an adjustable switching delay of up to approx. 8 seconds, any wave movements in the container are masked out.

As further special features, the probe relay (Ex) SRA-100-U0 offers line break monitoring with an alarm relay, a wide-range supply of 20 … 253V AC / DC and the option of using the electrodes in Ex areas (up to Zone 0).
