FOP and OPTV Kem Kuppers Fibreoptical Amplifier and Light Pulse Receiver

FOP and OPTV Kem Kuppers Fibreoptical Amplifier and Lightpulse Receiver
FOP and OPTV Kem Kuppers Fibreoptical Amplifier and Lightpulse Receiver

The integral pickup detects the r.p.m. of the gears and the FOP provides a flow-proportional light pulse signal. The OPTV receiver will convert the light pulses into a current or voltage squarewave signal.

Features

The FOP is a fibre-optic amplifier for KEM gear flow meters used in highvoltage applications. Its integral pickup detects the r.p.m. of the gears and the FOP provides a low-proportional light pulse signal. The OPTV receiver will convert the light pulses into a current or voltage squarewave signal which maybe used for evaluation.

Applications

  • Interference-free Pulse Detection
  • No Electrical Connection to OPTV Receiver
  • Anodised Aluminum Housing
  • Light Weight and Handy Design
