5842 HTS-MRPM Magnetic speed sensor

The magnetic speed sensor is suitable for applications where it is not possible to use optical measurement speed (eg. Due to the dimensions of the optical sensor). The magnetic sensor also ensures precise measurement speed without affecting the intensity of lighting and weather conditions.

The speed of the monitored object are measured with the aid of a permanent magnet fixed to the object and the sensor, in the immediate vicinity of the magnet moves. The best results are obtained when the distance between the sensor and magnet smaller than 1 mm.

The magnet can be glued with epoxy to the recess (projection of 4 mm and a depth of 2.5 mm) drilled e.g. the rear disc spinner, the flywheel of the car or helicopter. Due to the fact that for objects rotating at high speed is necessary to maintain their balance, the magnets are usually mounted in pairs symmetrically with respect to the axis of rotation. The second magnet is attached to the opposite polarity (indicated by "+" on the magnet) to affect the measured value. In contrast, in subjects with low speed measurement accuracy can be increased by using multiple magnets, the result must then be divided by the number of magnets - this correction can be performed automatically adjusting the propeller of the multiple number of sheets in the PC software or the transmitter Aurora 9. When using a magnet on the menu tachometer set on the Aurora 9 "Vrt.-M", respectively. "Prop-M", the two magnets "Vrt.-2 ', respectively. "Prop-2", etc ..

Holder with scanning Hall probe is mounted screws into the immediate vicinity of the path along which the moving magnet.

A set of sensors comprising: a sensor probe on the support cable, three magnets, two screws with nut M2,3x6 mm.
