Use in applications with coolants, cleaning agents and lubricants
The level sensors of the LK series provide reliable level detection in vessels and tanks. They are for example used to continuously measure the fill level of coolant containers or hydraulic reservoirs. The sensor displays the current level and signals via two switching outputs that the set limits have been reached or that the level is below the set limit. Setting to the medium to be measured and adjustment of the switch-on and switch-off points and switching functions of the outputs is simple thanks to the intuitive user menu. The sensors are available with three different probe lengths. The immersion depth is easily adjusted using the optional screw-in or flange adapters. The LK12 series is approved to the German Federal Water Act (WHG) section 19.
Features & Benefits
- Freely programmable switch-on and switch-off points with window function
- Units with scalable analog output and additional overflow alarm
- Clearly visible LED display
- Level and temperature monitoring with just one unit
- Optional: two configurable switching outputs for leakage detection
