Accelerometers
Datasheet
Bently Nevada Machinery Condition Monitoring
Description
The 20015x Accelerometers are general purpose, wide
frequency, case-mounted seismic transducers designed for
use with Trendmaster ProTIMs.
The 200150 Accelerometer also operates with the
Trendmaster 2000 system. The accelerometer interfaces with
the 200100 Dual Acceleration to Velocity flexiTIM Module and
the 89130-01 Acceleration-to-Velocity TIM (Transducer
Interface Module), as well as the 1900/25 and 1900/27
monitors.
The 20015x Accelerometers feature a hermetically sealed,
stainless steel case. This design provides an extremely
rugged transducer that is well suited for harsh industrial
environments. The transducer’s top-mounted, 5-pin
connector allows you to easily install and remove the
interconnecting signal cable. A 3/8-24 threaded hole on the
bottom of the sensor’s casing accommodates several
mounting options.
The 20015x Accelerometers contain a piezoelectric sensing
device that generates a charge when it is subjected to
vibration. The accelerometers electronically convert this
charge to a differential voltage signal that is proportional to
the acceleration that is parallel to the sensitive axis of the
transducer.

If you use the 200155 and 200157 Accelerometers with
1900 monitors or with TIMs other than those listed in
Table 1, or if you operate the transducers outside their
specified limits, machine monitoring may fail or the
data obtained may not be accurate.
The maximum allowed cable length for use with the
200155 is 15.24 m(50 ft.). You can install 20015x
accelerometers in a Class I, Zone 0 application without
a barrier, if you use them with the wSIM.

application
Fin-Fan,

transducers, consider what kinds of
data you need to obtain. Most common
machine malfunctions (imbalance,
misalignment, and so forth) originate at
the rotor and cause a change in rotor
vibration. The location you select on the
housing must accurately conduct rotor
vibration to the transducer.
Install the transducer carefully. If you
don't, the transducer may not
accurately detect vibrations and can
transmit invalid data. Bently Nevada

Note that the acceleration-to-velocity circuitry
in the 200200 and 200250 ProTIMs attenuates
frequencies above 1 kHz . You cannot obtain
higher frequency data with the 200155 or
200157.
The wider frequency range of the 200155 and
200157 accelerometers may result in increased
noise compared to the 200150. We recommend
that you use the 200155 transducer for
frequencies of interest below 10 Hz. Use the
200157 only if the application requires
acceleration enveloping. Use of the 200155 or
the 200157 in place of the 200150 may result in
faulty readings. Refer to the ProTIM datasheet
for the proper frequency response of the
system.
