VF5–Measuring transducer for frequency (square wave signal) : NORIS Group GmbH

Measuring transducer for frequency (square wave signal)
Simple application; for harsh environments
Compact design for mounting side by side
Fine adjustment of the measuring range via sealed integrated trimming potentiometer
Operating status indication via integrated LED
Ideal for shipbuilding industry, thanks to their construction and approvals

Measuring transducers of type VF5 convert frequencies (square wave signals) into standardised output signals. They are mounted on G rails or top-hat rails. The sensor input and supply voltage for the output signal are galvanically isolated. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
