LT-AV-EX

LT-AV-EX

Velocity Sensor

Application

  • Intrinsically safe explosion-proof certified product (AIECEx/ATEX/KCs)
  • 4~20mA output LT-AV series is compatible with most PLC, DCS, SCADA and Plant Information (PI) systems.
  • It is designed to monitor overall vibration levels of auxiliary rotating machinery such as
  • Motors & Generators,
  • Fans, Pumps & Compressors,
  • Small hydro turbines,
  • Cooling towers,
  • Piping Vibration, etc.

Features

  • Combined a vibration sensor, signal transducer and 4-20mA transmitter
  • Provide a cost-effective means of condition vibration monitoring system
  • 4~20mA current output signal is proportional to RMS velocity vibration
  • Compact size
  • Reverse wiring protection
  • Selectable full scale range
  • Selectable low and high pass filter
  • Must be used with certified safety barrier "LT-AV-Barrier" (IECEx/ATEX/KCs)
