Measuring transducer for frequency, input sinusoidal signal 1 2 • Straightforward application Messbe Meas.Rangreich: e: Umgeb. Amb. Tem Temp: p: • Compact construction • Galvanic isolation between sensor input and output signal to the operating voltage Measuring Transducers • Suitable for severe operating conditions • Frequency ranges to suit customer requirements • Provision made for fine adjustment of measuring range • Anti-tamper seal for the fine adjustment • Meet high EMC-requirements • Short-circuit-proof output selectable from • Operating characteristics displayed by integrated LED • Flame-inhibiting and self-extinguishing body • Suitable tacho-generators are available (NORIS devices GE..) 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 VFS5.., VFG5.. Description VFS5.., VFG5.. • Signal input for a sinusoidal frequency signal Electric isolation Sensor input and output signals are electrically isolated from • Suitable to evaluate outputs of speed pickups; the operating voltage. Multiple operation of amplifiers and evaluation AC-tacho-generators with various signal amplitudes devices is therefore possible at the same operating voltage. The • Suitable to evaluate outputs of NORIS sensor only supplies one amplifier device. GE..-tacho-generator-series with VFG5.. Output signal • Input range: 0 ... 10.000 Hz (according to type) • Maximum range fequency between: 50 ... 100 Hz (VFx500..), The output signal generated is a standardized voltage of 0 ... 10 V/DC or 2 ... 10 V/DC or, respectively, a standardized current of 0 ... 20 mA or 4 ... 20 mA. The output signal follows the input signal (Factory-set frequency adjustment) To avoid triggering errors the frequency full range set in factory strictly linearly (deviation < 0.1%). The output signal can be used to supply additional devices, such must be the highest frequency of the measuring chaine. as indicating instruments and limit-value switches. Attention should Input signal VFS5... be paid to the maximum driver capability of the output.
