Magnetic speed sensors manufacturing

Frequency 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 FTV signal converter's power input accepts a wide range of commonly used DC power.

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.

ZERO and SPAN adjustments easily calibrate to almost any measurement range, with little interaction between the adjustments.

Model 4028 Frequency To Voltage Converter

Model 4028 Frequency To Voltage Converters changes the frequency output of any magnetic speed sensor or hall effect speed sensor into a proportional 0-10V or 0-5V output signal. Compactly fits an explosion-proof ELBY 50 or 75 enclosure.

Power inputs can be configured for either a 2-wire or 3-wire power supply.
