Temperature Sensor for Veggie Oil Applications

Cars and trucks that are running on veggie oil would benefit on this easy to install temperature monitor since any veggie oil used in a diesel engine needs to be heated to ideally at least 160°F to achieve a low viscosity.

There are three temperature sensors that comprise this device and can be zip tied to coolant or veggie oil hoses to indicate the driver for the approximate temperature of the liquid inside which will let the driver obtain more information about the temperature of their veggie oil.

This temperature sensor is ideal for monitoring grease temperature level as well as determining when to flip from dynodiesel to veggie oil. It is also used in detecting cold spots and clogged filters where the grease temperature rapidly drops.

The temperature changes are measured based on resistance of the three thermistors where each thermistor sensor has four LEDs associated with it. As the temperature increases, the driver will see the each LED illuminate or turn ON which indicates that the grease has increased by 20°F in temperature since the temperature range is 65°F to 135°F. The sensor peaks low for the fuel hose insulation.
