Although the integral cable has built-in strain relief, do not use excessive force
when pulling cable. No more than 5-lbs. of force should be exerted directly on
the senor connection during installation. It is recommended that the cable be
secured to the machine near the point of sensor installation if possible.
For sensors that have been mounted before pulling the cable through the
conduit or raceway to the junction box, leave the cable bundled and secured
to the machine. Permanent signal degradation takes place when cables are
damaged. Do not step on, kink, twist or pinch cables. Also take note of the
placement of the cable bundle. Do not place bundles in a manner causing
strain at the sensor/cable connection.
SENSORS
Preferred Method of
Mounting Sensors
Drill and Tap (Stud Mount)
The preferred method of mounting sensors to a machine is the drill and tap
(stud mount) method. Drill and tap mounting is preferred because it provides
increased reliability, improved frequency response, and increased signal
sensitivity.
This method of mounting to a machine is:
1. Drill into the machinery.
2. Tap the hole
3. Insert the mounting stud.
4. Directly mount the sensor to the surface of the machine.
Epoxy Mounting
If the machinery cannot have a hole drilled into it, the epoxy mounting method
is acceptable, though it is less reliable and the sensor performance is
degraded at high frequencies. The epoxy mounting method is:
1. Glue a mounting pad to the machinery.
2. Insert the mounting stud.
3. Attach the sensor to the pad.
Tools and Supplies
Below is a list of required tools and parts necessary to install the sensors.
•Drill
• Spot Face and End Mill Tool
The spot face tool may be purchased form Emerson’s Machinery Health
Management business. Please contact your local sales representative for
assistance.
