https://www.electronics-lab.com/project/frequency-to-voltage-converter-tachometer-variable-reluctance-magnetic-pickup-to-voltage-converter/

The circuit shown here is a frequency-to-voltage converter that can be used in many applications. This is a signal conditioner for Variable Reluctance Magnetic Pickup Sensor used in engines or machines to detect the speed by sensing gears’ teeth. The input signal level is 20mV to 28V. The circuit provides 1V (67Hz/Volt) when the input […]
