The linear resistance to voltage module was designed for the eTape liquid level sensors. The eTape sensor plugs directly into the four-pin header on the module. The module is designed to convert the variable resistance output of the eTape liquid level sensor to a linear output voltage between ~0 volts to ~5 volts DC. Applying the output voltage of the module to a microcontroller, PLC or other voltage monitoring device can more accurately measure and monitor the liquid level output of the eTape sensor. The module is calibrated using a five-point calibration process at 0%, 25%, 50%, 75% and 100% of full scale. See the datasheet for calibration instructions.
