3.2.5 Other interfaces
3.2.5.1 USB service interface
A USB service interface is available internally, for SKF use only or under the direction
of TSG or SKF application engineers
3.3 SKF Enlight Collect IMx-1 wireless sensors
3.3.1 Installation considerations
When selecting a location for the sensor bear in mind that the sensor is single axis,
the vibration sensitive axis is through and perpendicular to, the mounting face.
Choose an appropriate installation position:
• Suitable for the machine vibration/temperature measurement envisaged
• Avoiding unnecessary exposure to sources of radiant heat
• That doesn’t impede routine maintenance of the machine
• Where the transducer is not easily damaged
• Of a suitable size and with clearance for mounting and accessing the sensor
• With the mounting area suitably prepared to ensure a good contact interface
• Mount it securely using stud or adhesive-stud mounting
3.3.2 Mounting detail
Once the mounting/measurement point location is decided, prepare the surface
appropriately:
• For direct stud mounting, drill and tap to suit the stud being used and spot
face an area if necessary. Recommendations:
o Depth: greater of 8 mm (0.31 in.) or stud length plus 2-threads.
o Drilled perpendicular to the mounting surface, within ±1°.
o Flat mounting surface for the IMx-1 – within 25 µm (0.001 in.).
o Surface roughness no greater than 0.8 µm (32 µin.).
o When fitting, ensure there is no gap between the mounted sensor and
the mounting surface.
• For adhesive stud mounting, remove paint, clean and apply the adhesive.
Apply activator to the stud base, position and apply pressure until the
adhesive cures.
Note that the mounting detail of the IMx-1 sensor is identical to the SKF Wireless
Machine Condition Sensor, CMWA 8800, and being as the IMx-1 is a little shorter,
the same tools and similar procedures can be applied.
