VFG5–Measuring transducer for frequency (sinusoidal signal) : NORIS Group GmbH

Measuring transducer for frequency (sinusoidal 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

Measuring transducers of type VFG5 convert frequencies (sinusoidal 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.
