Kem Kuppers FOP and OPTV Fibreoptical Amplifier and Light Pulse Receiver

Description

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

Features

The Kem Kuppers 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 Kem Kuppers FOP provides a low-proportional light pulse signal. The Kem Kuppers 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
