Description
The 20015x Accelerometers are general purpose, wide
frequency, case-mounted seismic transducers designed foruse with Trendmaster ProTIMs.
The 200150 Accelerometer also operates with theTrendmaster 2000 system. The accelerometer interfaces withthe 200100 Dual Acceleration to Velocity flexiTIM Module andthe 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 theinterconnecting signal cable. A 3/8-24 threaded hole on thebottom 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 tovibration. The accelerometers electronically convert thischarge to a differential voltage signal that is proportional tothe acceleration that is parallel to the sensitive axis of thetransducer.
If you use the 200155 and 200157 Accelerometers with
1900 monitors or with TIMs other than those listed inTable 1, or if you operate the transducers outside their
specified limits, machine monitoring may fail or thedata obtained may not be accurate.
The maximum allowed cable length for use with the200155 is 15.24 m (50 ft.). You can install 20015x

If you are measuring a machine
housing to determine where to installtransducers, consider what kinds ofdata 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 notaccurately detect vibrations and cantransmit invalid data. Bently Nevada
provides engineering services toaccurately measure machine housingsand to install transducers.

Note that the acceleration-to-velocity circuitry
in the 200200 and 200250 ProTIMs attenuatesfrequencies above 1 kHz . You cannot obtainhigher frequency data with the 200155 or
200157.
The wider frequency range of the 200155 and200157 accelerometers may result in increased
noise compared to the 200150. We recommendthat you use the 200155 transducer for
frequencies of interest below 10 Hz. Use the200157 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 thesystem.
