This device aims to convert a frequency signal to an analog signal with less than 5 % linearity error. The input frequency signal is a 0 - 10 kHz, 30 - 100mV pk-pk signal from a hall effect sensor. The output analog signal is the standardized 0 - 10VDC and 4 - 20mA DC signal. The device is meant to act as a data acquisition unit to be used in industrial applications, such as motor control. In our case, the frequency signal is from a hall effect sensor. The design consists of four sequential blocks and is powered by a 24VDC power supply. First, the input frequency signal is inputted into a Schmitt trigger which will convert the signal into a 5V perfect square wave of the same frequency, to be fed into the computing unit, which will output a corresponding 0 - 5 VDC. The voltage is then amplified by 2 with the use of a voltage op amp, achieving a 0 - 10 VDC output. If current is the selected output type, the 0 - 10V signal is switched into inputting into the current transmitter, creating an output current loop of 4 - 20 mA DC.
