Fuel Level Sender (1) Sender. (2) Schematic symbol.Fuel level sender (1) provides fuel level sensing. A resistive signal which corresponds to the depth of fuel within the fuel tank is sent from the sender to the main display module. The main display module measures the resistance value in order to determine the fuel that is remaining in the tank. Typical gauge readings for the fuel level:

Temperature Sender (1) Schematic symbol. (2) Sender.Temperature sender (2) provides a method for sensing fluid temperature. The temperature sender produces a resistive signal which corresponds to the temperature of the fluid that is being monitored. Typically, the resistance range of the sender is from 70 ohms at 110°C (230°F) to 3000 ohms at 25°C (77°F). The main display module measures the resistance value in order to determine the fluid temperature.
