Transducer Installation (continued)
AMCI Transducer Mounting Guidelines
All AMCI resolver transducers are designed for industrial environments and therefore require little attention.
The resolver is electrically isolated from the body of the transducer to eliminate the potential for ground loops
and ground shifts in the system. The main guideline to follow when mounting the transducers is to limit bear-
ing loads when coupling the transducer to your machine. This includes using flexible couplers when directly
coupling shafts to eliminate shaft misalignments.
The following bearing load ratings are known as “L
10
ratings” in the bearing trade associations. L
10
is a stat-
ical rating meaning that 90% of the bearings will survive the specified number of revolutions. AMCI speci-
fies our rated number of revolutions as 2X10
9
, or 2 billion, which is a number commonly used in the industry.
By specifying the maximum load and statical life, AMCI gives you data you need to choose the right trans-
ducer for your application.
Note that these load ratings are maximums, and you should always strive to keep shaft loading to a minimum.
The inverse relationship between shaft loading and bearing life is not linear, it's exponential.
This means that decreasing the shaft loading by half will, statically, increase the bearing life by a factor of
eight. For example, decreasing a shaft load from 100 lbs. to 50 lbs. yields: [100/50]
3
= 8 times increase in sta-
tistical bearing life.
At the loads specified below, bearing life is a minimum of 2x10
9
revolutions. Note that the R11 series and
HT-6 transducers always require a flexible coupler to your machine because of their shaft sizes.
Transducer Cabling
Suggested Cable
For cable lengths less than 100 feet, AMCI suggests Belden 9873 or an equivalent cable. For cable lengths of
100 feet and greater, AMCI suggests Belden 9730 or an equivalent cable. Note that Belden 9730 can also be
used for cable lengths less than 100 feet.
