Measuring transducer, frequency type to correct for wheel/tyre wear on rail vehicles 1 2 Straightforward application Suitable for severe operating conditions Compact construction Tyre diameter setting by means of Nenn-Rad nominal tire reifen : dia: tamper-evident drum scale • For all commercial tyre diameters Umgeb. Amb. Temp Temp: : Measuring Transducers Galvanic isolation between sensor input and and operating voltage to the output signal Meet high EMC-requirements Short-circuit-proof output selectable from Operating characteristics displayed by integrated LED Flame-inhibiting and self-extinguishing body Suitable speed sensors are available (NORIS devices FA../ FT..) Measuring transducers of series 5 Measuring transducers of the Series 5 are designed to convert electric input values into standardised output signals. Principle of operation: The transducer signal measured at the converter input is converted into a standardised output signal that is proportional to the input and lends itself to further customised processing, for instance, in a machine controller. General notes on Type VF5xxKDx-x Description VF5..KD.-. The type VF5..KD.-. is designed to compensate signal output of the Output signal The output signal generated is a standardized voltage of speed sensor to allow for the diameter of the tyre, when worn.

The output signal follows the input signal strictly and turning-down of the tread would result in high readings. linearly (deviation < 0.1%). The output signal can be used to supply additional devices, such as Details VF5..KD.-x. • Signal input for a NORIS standard frequency signal indicating instruments and limit-value switches.

The operating voltage required by the sensor is provided by the Electric isolation measuring transducer. The operating voltage and sensor input are electrically isolated from the output signal. Therefore, multiple operation of amplifiers and evaluation devices is possible at the same operating voltage and from only one sensor.
