FOP and OPTV Kem Kuppers Fibreoptical Amplifier and Light Pulse 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
