The product series by Müller Industrie-Elektronik, especially the MK series of modular compact sensors, covers nearly all physical measuring categories like temperature, pressure, differential pressure, filling level and flow with a variety of electrical connection options.


The MK series "Modular Compact Sensors" is designed for the application in exceptionally rough environments and the adverse conditions appearing there. The robust material of basic body consisting of stainless steel, the compact construction form with small dimensions and the protection class IP67 makes the sensor of MK series suitable for almost all industrial applications. The temperatur sensor MKTS-GL is granted for DNV GL approval and is suitable for the use in shipbuilding and ship industry.

In addition the sensors of MK series are applicable in food industry and general applications in all areas of industry for heating, ventilation, and air conditioning also optimally suitable for application in engines, aggregates and mobil hydraulics. The sensors of MK series guarantee high exactness with low servicing expenditure and deliver absolutely reliable measuring values for long operation durations.

Applications for sensors of MK series:

Compact temperature sensor MKTS:

The MKTS is developed as a standard sensor for applications in climating, ventilating and heating installations. Due to the used materials and the compact design, this sensor with its small dimensions is very robust. The programmable transmitter reduces storekeeping. The sensor type MKTS-GL is available with DNV GL approval and therefore is applicable especially for the use in ship and port industry.

Compact flow sensor MKFS:

For use in applications where measuring of flow is necessary to show tendency of flow rate, as in climating, ventilating and heating installations, fire extinguishing plants or aggregates. Due to the used materials and the compact design, this sensor with its small dimensions is very robust.

Compact level sensor / switch MKLS:

Suitable as a level limiting value switch, a level sensor in simple control loops or as indication for tendency of level. For use in industrial plants, terotechnology and public utility (e.g. tanks for hydraulic oil). Due to the used materials and the compact design, this sensor with its small dimensions is very robust.

Conductivity level switch MKCS:

Suitable as a level limiting value switch in conductive aqueous solutions in simple control loops. For use in industrial plants, terotechnology, public utility and machines.

Temperature switch MKTL:

For use as temperature limiter in machines or devices (e. g. switching-off, switch on of cooling) as possible for mobile hydraulics, motors or compressors with the following advantage: The switch is self-operated.

Compact differential pressure transmitter MKDS:

The pressure sensor is suitable to measure differential pressure. From this measuring value can be derived: flow rate (volumetric- and mass flow) and level (level, volume, mass). Typical areas of use are chemical industry and process engineering.
