AV02-03-0.08

Purpose:

  • Measuring vibration velocity in stationary diagnostic systems with standard current output (4–20 mA).

Features:
  • Conversion of a piezoelement signal proportional to vibration velocity into a standard current signal 4 … 20 mA.
  • HART-protocol (Highway Addressable Remote Transducer Protocol) – digital industrial protocol for transfer of data superimposed on a current analog loop of 4 … 20 mA.
  • Electric insulation of piezoelement and built-in amplifier-transducer from the body eliminates the influence of grounding loop currents on measurement results.
  • Robust design, waterproof casing and non-detachable armored cable.
  • Stable characteristics and reliable operation.
  • Transmission of current signal at a distance of up to 500 m.
  • Evaluation of machines vibration according to GOST ISO 10816-3-2002.
  • Explosion-proof version 1ExibIICT4 (optional).
