Transducers for frequency

Measuring transducer for frequency (sinusoidal signal)


Measuring transducer VFS5

  • 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
  • Ideal for shipbuilding, thanks to their construction and approvals


Measuring transducers of type VFS5 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.
