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

Electrical Data, Alternatively

Voltage outputs (3-wire connection)

a. Active output High level: Uhigh > UB - 0.6 V - [2.5 kΩ × Iout (mA)]

Low level: Ulow < 0.6 V + [1.3 kΩ × Iout (mA)]

b. Passive output

High level: Uhigh > U - [Iout (mA) × 1.3 kΩ] Low level: Ulow < 0.6 V + [1.3 kΩ × Iout (mA)]

U is the voltage applied at the output, max. 30 V

Current output (2-wire connection)

a. For UB < 9 V (NAMUR supply units)

High level: Ihigh > 2.2 mA
Low level: Ilow < 1.1 mA

b. For UB 7 up to 30 V

High level: Ihigh = [(UB - 0.6 V)/1.3 kΩ] + Ilow
Low level: Ilow = (UB - 4 V)/7.5 kΩ

Frequency Range3 up to 1,500 Hz according to flow meter
Electrical ConnectionTwo off 4-pin screw terminals for supply and output signals (see wiring schemes)
