The LMK 458 has been developed for measuring level in service and storage tanks and is as a consequence certificated for shipbuilding and offshore applications. A permissible operating temperature of up to 125 °C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the LMK 458 is a capacitive ceramic sensor element designed by BD\SENSORS, which offers a high overload resistance and medium compatibility.

The separable plastic immersion probe LMK 858 was designed for level measurement in aggressive media, desalination plants and for use in more viscous media such as sludge. Since the area of application is often outside a building, great emphasis was placed on high surge / lightning protection. The immersion probe is based on an extremely robust and precise pressure sensor, the membrane of which consists of a high-purity ceramic. Another special feature of the LMK 858 is the separability of the probe head and cable part.

The detachable plastic submersible probe LMK 808 was developed for level measurement in water and wastewater. The basis of the probe is an extremely robust, almost maintenance-free capacitive ceramic sensor. For level measurement in river courses, on weir systems or in locks, great emphasis was placed on overvoltage / lightning protection. In addition, the cable can be protected against bites if necessary. The sensor head can be separated from the cable part and can therefore be replaced if necessary without time-consuming assembly work.
