Signal Converter

FTC/FTV Converter, Digital-Digital Converter

Frequency to Current and Frequency to Voltage Signal Converters are used to transform the sinusoidal output of a Variable Reluctance Speed Sensor to an analog current or voltage signal. The signal will remain a constant current or voltage at a specific flow rate (e.g., 4 mA at no-flow and 20 mA at maximum flow).

Available in puck style housings that can be mounted in electrical cabinets or dropped into conduit elbows and enclosures.

The 4026 Converter incorporates both FTC & FTV conversion circuits (e.g. 4-20 mA or 0-10V Analog output signals) and includes the option to convert a digital output (square wave signal).

Intrinsically Safe and Explosion/Flame Proof versions are also available for Hazardous Locations.

Digital to Digital converters are used to convert one digital output (square wave signal) to another.


  • Flow metering
  • Engine speed (crank and flywheel)
  • Conveyor / Process speed
  • Retrofit new electronic systems to older equipment

Alternative Products

Amplified Variable Reluctance Sensors integrate an amplifier circuit built into the sensor housing. These sensors offer a wide range of digital output options.

Signal Amplifiers (Pre-Amps) are used to transform the sinusoidal signals of VR Speed Sensors to a digital output (square wave signal).

Digital Scalar can multiply or divide both sinusoidal and digital signals to adjust the frequency through an LCD interface. It can also optionally convert to analog current or voltage signals.

Hazardous Locations Sensors for use in explosive atmospheres are also available.
