Freq to Voltage Signal Converters
SPECTEC's frequency to voltage converters adapt to many applications with their wide variety of field selectable input voltages and output variables their capacity to operate in environments with a wide temperature range.
The ZERO and SPAN adjustments on all signal conditioner models allow them to be calibrated to almost any measurement range, with virtually no interaction between the adjustments.
The power supply input on all the signal converters covers a wide range of commonly used DC power without a need for selection. Supply input is protected against reverse polarity wiring and outputs are protected against supply, ground or signal out continuous short circuits.
Model 4026 as Frequency to Voltage Converter
Model 4026 Frequency to Voltage converter is very versatile with field selectable inputs and outputs, giving your field technician the ability to convert the input signal from any passive magnetic speed sensor, Hall effect sensor, or digital magnetic speed sensor.
Input range is adjustable between 1100 Hz - 10 kHz or 75Hz to 1100 Hz. Output selection can be configured as 0-5 V FTV converter or 0-10 V FTV converter.
ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments.The field selectable frequency to voltage output for the converter can be configured as either 0-5V or 0-10V volts.
Model 4028 Frequency To Voltage Converter
Model 4028 Frequency To Voltage Converters converts the frequency output of any passive magnetic speed sensor, VR sensor or hall effect speed sensor into a proportional 0-10V or 0-5V output signal. The Model 4028 FTV converter compactly fits an explosion-proof ELBY 50 or 75 elbow enclosure.
The frequency range is field selectable to fit most applications. Input range is adjustable between 1100 Hz - 10 kHz or 75Hz to 1100 Hz. ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments. Power inputs can be configured for either a 2-wire or 3-wire power supply.
Model 4057 as Frequency to Voltage Converter
Model 4057 Programmable Frequency to Current/Frequency To Voltage Converter Users can select from various modes of digital frequency output, while simultaneously providing an analog output. The analog output option can be set to convert the input frequency to either a proportional voltage (FTV) or current (FTC).
4057 Signal Converter accepts signals from magnetic VRS, digital sensor signals - both digital magnetic and hall effect sensors - as well as RF sensors.
The digital output may be programmed to multiply, divide, or apply a K-factor scalar to the input frequency.
