The Basics
The CMWA 8800 Sensor

SKF Wireless Machine Condition Sensor
Service Manual
CMWA 8800 Label
The label on the base of each sensor displays the Hardware Version and the MAC
address. The MAC address is assigned by SKF and it serves as a physical identification
and does not change. The first ten characters of the MAC address make up the
manufacturer and product’s unique ID number (00-1B-1E-E1-A2) assigned by the
HART (Highway Addressable Remote Transducer) Communication Foundation; the last
six characters are the unique device ID assigned by SKF. The label also includes the
operating temperature range, model number, bar code, mounting torque, CE
certification number,
FCC/IC certification number, icon indicating
do not throw away the
sensor as trash, and the warning “Sensor shall not be opened by unauthorized
personnel.”
CMWA Long Tag
SKF @ptitude Analyst (called Analyst in this Service Manual) and the Wireless Sensor
Device Manager software (called Device Manager in this Service Manual) use the asset
name as the Long Tag to identify the sensor. The Long Tag contains 32 characters
under the WirelessHART protocol, but Analyst permits only 20 characters so the Long
Tag is truncated. If the truncated tag has a duplicate in the Analyst database, Analyst
appends the names of the subsequent
POINT
s with .1, .2, and so on.
The Long Tag
identifier can be changed in Device Manager.
Repair Service
All repair service must be done at a certified repair center – currently San Diego is the
only center. The sensor will be inspected to determine whether the plastic top was
twisted or opened in the field, which would void the warranty.
The expected type of service is battery replacement. The sensor has no repairable
parts. If the printed circuit board (PCB) is not in working condition, it can be replaced at
the customer’s request. The MAC address of the new PCB will be modified to match
that of the original sensor. The serviced sensor will be fitted with new top, label, and

ring.
