The bracket fastening screw of state testing source generating means, movable sensor mounting bracket to sensor fix to clamp quick positioning
At platform (bracket activity non-operative end spacing place), the magneto-electric or current vortex speed probe that scene is used are inserted into sensor
Folder hole is fixedly mounted, sensor head fixes to clamp rapid positioning platform with sensor and contacts.Since sensor fixes to clamp fastly
Fast locating platform is on cabinet table top and 1mm higher than cabinet table top, rosette group and cabinet table top in same level height, this
For sample it is ensured that when movable sensor mounting bracket is to bracket active operation end spacing place, sensor can be vertically fixed on metal
Disk hole operates the surface of track, apart from rosette plane 1mm distance.It can also be according to zero for current vortex sensor
Position output voltage adjusts fixed position.Movable sensor mounting bracket is to bracket active operation end spacing place, locking bracket fastening
Screw, such sensor just install.Sensor signal lines, which still connect, not to be had to move in the actually detected circuit of tachometric survey at the scene
Or it is independently accessed in the equipment such as rotational speed meters, oscillograph, frequency meter.It cuts in frequency outside the generating means of sensor dynamic measuring signal source
Power supply source turns on the power switch by adjusting speed regulation knob adjustment motor speed change, observes rotating speed measured value situation of change, this
Whether the dynamic property that sample can test sensor meets requirement, and guaranteeing being capable of normal reliable use after sensor is online.
By rotation the first rosette of adjustment allow thereon positioning groove change with positioning groove lap position on the first rosette
The quantity in variable orifice hole, in this way in the case where motor fixed rotating speed, the signal that tach signal occurring source issues will change at double, side
Just the judgement of sensor dynamic property.
The present invention is to be believed using the rosette group of motor driven belts hole using the rotation of certain revolving speed as measurement of rotating speed
