200150 Accelerometer

Accelerometer

The 200150 Accelerometer is intended for use only with a compatible Transducer Interface Module (TIM) as part of our Trendmaster® Pro quasi-continuous online condition monitoring system. This acceleration transducer features a frequency response suitable only for general purpose applications. When machinery with slow rotative speeds will be monitored, use the 200155 and an appropriately configured proTIM instead. For acceleration enveloping applications, use the 200157 and an appropriately configured proTIM.

200155 Low-Frequency Accelerometer

The 20015x Accelerometers are general purpose, wide frequency, case-mounted seismic transducers designed for use with Trendmasterâ proTIMs.

200155 Low-Frequency Accelerometer

link-200157-accelerometer

200157 High-Frequency Accelerometer

The 20015x Accelerometers feature a hermetically sealed, stainless steel case. This design provides an extremely rugged acceleration 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.

link-200350-200355-accelerometer

200350 and 200355 Accelerometers

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.

Cables

Operating Temperature Range

-20 ºC to +100 ºC (-4 ºF to +212 ºF)

These cables may be used at lower temperatures if the installation prevents the cable from flexing or bending. Flexing these cables at temperatures below –20 ºC (-4 ºF) may damage the cables.

Construction 4-conductor, 22 AWG with braided shield and drain wire (85% coverage, minimum), PVC outer jacket. Nickel-plated coupling nuts.
Seal Connectors provide an IP67 seal to transducers and mating hardware. Connectors are molded to the cable. The addition of DC4 electrical insulating compound in the connectors provides additional protection against moisture during a thermal shock.
Minimum Bend Radius 200151 63.5 mm (2.5 in)
Minimum Bend Radius 200152 73.7 mm (2.9 in)
Maximum Cable Length

25 m (82 ft)

Custom products may be able to provide longer cable lengths for the 200150 and 200157 accelerometers.

Adhesive (see Mounting Hardware Options)

Temperature Range -55 ºC to +121 ºC (-67 ºF to +250 ºF)
Cure Time 24 hours
