mainSENSOR is based on an innovative measuring principle, which has been developed by Micro-Epsilon in order to combine the advantages of both inductive and magnetic sensors. Magneto-inductive sensors are frequently used as alternative to inductive sensors and proximity sensors in process automation, the packaging industry and in machine monitoring. Measuring the distance to a magnet which is fixed at the measurement object, the sensors outputs a continuous, linear output signal. As different strength magnets are applied, measuring ranges of between 20mm and 55mm can be achieved. However, in order to adapt the measuring range, it is only necessary to change the magnet.
Flexible sensor concept - one electronics in various housings
Due to their flexible concept, the sensors are ideal for a wide range of applications, particularly where high volumes are required. The standard sensors are designed in a stainless steel M12, M18 and M30 or a flat plastic housing suitable for industrial applications. In high volume production, customer-specific modifications to the plate and sensor housing can be easily achieved.
Measuring through non-ferromagnetic materials, particularly metals
Unlike conventional measuring methods, the magneto-inductive sensors enable measurements through non-ferromagnetic materials, particularly metals such as aluminum or stainless steel. A clear benefit is provided here as the sensor and the magnet can be installed separately in applications with closed systems or housings. It is therefore possible to mount the sensor safely in harsh environments.
mainSENSOR is also used for rotational speed measurement. In order to do so, one or two magnets are mounted on the rotating measuring object. Regardless of the direction of rotation, the sensor measures the speed of the target object.
