2.2.3 Installating mounting brackets and sensors
1. Install the mounting bracket on the
structure at the chosen location.
2. Adjust the sensor at mid-range
distance from the target, using a
gauge between sensor face and
target. Refer to the specifications of
the LIN-300 Series module used
3. Set the sensor in place by tightening
jam nuts at recommended torque.
When adjustment has been
completed and measurements have
been validated, thread lock
compound must be applied to prevent
the nuts from loosening.

Caution
Proceed with gap distance adjustment only after the complete measuring chain,
including grounds
,
has been installed. Apply power to the measuring chain, and measure signal output. The distance is
correct when the conditioner output reads precisely 12 mA.
Grounding
The principle of operation of the PCS-200ESB sensor requires adequate high-frequency grounding. To
ensure the permanent conductivity of the ground, some precautions must be taken during installation.
•
On a grounded metallic structure, avoid the use of paint or sealant inside and around mounting holes
on the mounting bracket. This will ensure electrical contact between the sensor body, the mounting
bracket, and the machine.
•
When a direct electrical contact between the mounting bracket and the machine cannot be achieved
(for instance, when the mounting bracket is installed on concrete), a grounding copper wire must be
installed between the metallic mounting bracket and the nearest location of a grounded structure.
•
In the presence of insulated bearing, special caution must be used. Refer to the following instructions
for installation of the mounting bracket on an insulated bearing.
