🧠 What Is Frequency to Voltage Conversion?

Frequency is the number of cycles a signal completes per second, measured in Hertz (Hz). Voltage represents electrical potential, measured in Volts (V).

A Frequency to Voltage Converter is a system or circuit that translates a varying frequency input signal into a proportional DC voltage output. This is commonly used to:

• Convert frequency signals from sensors (e.g., speed sensors, flow meters) into readable voltage levels
• Control devices like variable frequency drives (VFDs) or PLCs
• Interface frequency-based signals with analog measurement systems
• Monitor the frequency of alternating current sources or oscillators

For example, if a sensor outputs 100 Hz per 1 volt, a signal of 500 Hz would convert to 5 V.

📝 Frequency to Voltage Conversion Formula

The basic formula for linear frequency-to-voltage conversion is:

Where:

• 𝑉 = Output Voltage (Volts)
• 𝑓 = Input Frequency (Hertz)
• 𝑘 = Conversion Constant (Volts per Hertz)

The conversion constant depends on the specific system or circuit you are using. Some sensors or devices provide this constant in their datasheet.

Example:
If a sensor has a conversion factor of 0.01 V/Hz and the input frequency is 250 Hz:

This means the output voltage corresponding to 250 Hz is 2.5 volts.
