Measuring transducer for frequency (three-phase generator)
Measuring transducers of type VFW5 convert the signal from a 24 V three-phase generator 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.
