Digital Frequency-Voltage Transducer, FVM 70/82

General Description

These transducers convert a frequency signal of any form and polarity into a normalised voltage or current signal (e.g., 0-10 V or 4-20 mA). The measurement range is selected via DIL-switches on the reversal of the unit. The standard version has 64 calibrated ranges from 0-100 Hz to 0-28.8 kHz.

Special versions are available for low frequencies (FVM70/82 – L). The measuring range can be selected via DIL-switches in steps of 0.1 Hz between 0-0.1 Hz and 0-12.7 Hz or in steps of 1 Hz between 0-1 Hz and 0-127 Hz. The analog output signal is completely ripple-free.
Version FVM70/82-2L allows the adjustment of the measuring range in steps of 10 Hz between 0-10 Hz and 0-1270 Hz. The analog output signal is completely ripple-free.

• For flow measurement and other frequency signals
• Digital frequency to voltage conversion, extremely accurate
• Schmitt-trigger input protects against interference, AC-coupling
• Low frequency versions, ranges down to 0-0.1 Hz, rippel-free output signal
• Control LED on units with 24 V power supply
• Different housings available
