IEPE accelerometers

Model 786A, 787A, 786B-10, 787B, 780A, 780B, 780C

IEPE accelerometers for rotating machinery: general purpose, high/low frequency, triaxial, dual vibration and temperature, radiation-resistant and underwater types.

Description

Wilcoxon's IEPE accelerometers monitor vibration on rotating machinery such as motors, fans, pumps, gearboxes, compressors and spindles for predictive maintenance. The range includes underwater accelerometers, and the company lists vibration monitoring on marine vessels among the applications of its integral-cable accelerometers.

Key features

  • General-purpose 100 mV/g sensors, e.g. 786A (top exit) and 787A (side exit) with ±5% sensitivity tolerance, and the compact 780 series
  • High-frequency, low-frequency, high-temperature, intrinsically safe and Class I Division 2 versions
  • Dual vibration + temperature, triaxial, velocity, high voltage isolation, radiation-resistant, low-power, helicopter and underwater types
  • Hermetic sealing verified by helium leak testing
  • Less than 1% sensitivity drift over 10 years

Applications

Condition monitoring of pumps, motors, compressors and other rotating machinery in industrial plants and on marine vessels.
