Question 1

Mounting instructions

Accepted Answer

Number of sensors		Sensor location
	Primary: 1 Optional: 1	Radial Horizontal-DrivenEnd motor Radial Vertical-Non-DrivenEnd motor

It is suggested that mounting locations greater than 80cm apart also use the optional location.

As a rule, it is recommended that you mount the sensors vertically or horizontally to the shaft at each rolling bearing point of the machine.
Sensor installation in a fixed machine structure without elastic intermediate layers, e.g. protective covers
The alignment of the measurement axes must be observed; ideally one measurement axis should be vertical to the shaft (= load zone) and one measurement axis each horizontal and axial to the shaft.
A permanent screw connection is preferable, but mounting accessories such as adhesive adapters or magnetic adapters can also be used if required.
If machines are considerably larger than 0.5 m, it is recommended that at least two sensors be used at each bearing seat. This also applies to machine parts separated by a coupling or other components.
