4. Installation Method
4-1. Installation of Sensor
Sensor detects vibration on the bottom. Therefore, it is an important condition for
detecting vibration that the bottom surface is in close contact with the vibrating part.
Ideally, the surface of the equipment on which the sensor will be installed should be as flat
as possible, and the contact surface should be coated with silicone grease or oil (Fig. 5-1).
Fig.4-1 Installation of Sensor
Caution
Be sure to check the following items before installing sensor.
(1) Is the instrument to be measured grounded
If sensor mounting surface (measurement target instrument) is not
properly grounded, sensor may become charged and may fail.
(2) Is the sensor mounting surface cleanly finished
Completely remove dirt, dust, paint, etc.
Also, make sure that the tapped holes
are upright with no foreign matter on the threads.
Processing of sensor mounting surface
The degree of close contact between sensor and mounting surface directly affects the
characteristics of sensor.
Especially, since acceleration sensor measures up to high frequencies, make mounting
surface flat and tap M6 female screw perpendicular to mounting surface (Fig. 4-2).
