MK Series: Modular Compact Sensors

The product series of modular compact sensors is developed for the application in exceptionally rough environments and the adverse conditions appearing there. The MK series covers nearly all physical measuring categories like temperature, pressure, differential pressure, filling level and flow. The robust material of basic body consisting of stainless steel, the compact construction form with small dimensions and the protection class IP67 make it 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.
