10V oil level switch sensor,
300mm oil level switch sensor,
24V universal oil level sensor
TSC-70 sensor with capacitance as the sensitive element, TSC-70 sensor series continuous detects the height of the fuel level with less than 1mm resolution. Sensor length can also be shorter to fit tanks with different heights. TSC-70 sensor can replace the original fuel level sensor on vehicles and connects with oil gauge. With wide range of voltage input, it has no limitation to input voltage.
1. Technical parameter:
Sensor length: 200~ 1000mm, any length available within this range
Wide range of power supply: DC10V ~ 32V
Maximum operating current: < 15mA
Working temperature: -40 ~ 85℃
Material of the tubes: Aluminum ally
Application environment: diesel, biodiesel, gasoline, kerosene
(Not applicable to conducting medium)
Protection rank: IP65
2. Mode of connection:
Pin2: V out (0.5~4.5V or );
Pin4:Connect to calibrator;
Pin5:Connect to calibrator;
Pin6:Connect to calibrator;0~5V
Calibrator must couple with the sensor, and it has 12V/ 23A battery inside.
Red light is the power light. If the light isn't on when switch on, battery replacement is needed;
Green light is the calibration light. Full/ Empty button is showed in above picture.
Note: Calibration is necessary before using the sensor due to different fuel types;
4. Length adjustment and Calibrator:
4.1 Adjustment of sensor length
Aluminum tube at the bottom can be shorter according to different requirements from customers. Steps are as follows:
4.1.1 Customer specifies the sensor length according to the needs;
4.1.2 Cut the unwanted part with steel saw;
4.1.3 Get rid of the burrs and the debris at the cutting area with blade or a screwdriver to avoid short circuit.
4.1.4 Take down the filter unit, take out the plug, and assemble the plug in the aluminum tube, then assemble the filter.
4.2 Calibration of the fuel level sensor
Calibration of the fuel sensor is calibration of the full level and empty level. The fundamental principle is to record a full value and
empty value in the fuel sensor when tank is full and empty; defining the positions of fuel is full and empty in the tank. The electrical
signal changes as the fuel level changes, calculating the height of the fuel level.
Note: when the fuel sensor becomes shorter, it shall be recalibrated. Calibration to empty level and full level is related to the medium
and the fuel level, instead of volume of the tank, so this operation can be operated in room (make a container, full filled with diesel,
simulation of the tank). Calibration of full level shall go first, then the empty level, or else, it is impossible for the sensor to enter the
4.2.1. Calibration of full level
Full fill the tank, put sensor into the tank, wait for about 30s till the aluminum tube of the sensor is full of fuel, then press the “full” button
on the calibrator for 5 seconds till the green LED light slowly flickers, it indicates that calibration enters full level mode. The green LED
light is off after about 10 seconds and it indicates that the calibration of the full level is OK.
4.2.2. Calibration of the empty level
Take the sensor out of the tank; put it outside of the tank. When all the fuel flows out of the sensor, press the “empty” button for 5
seconds till the green LED light flickers fast, it indicates that calibration enters empty level mode. The green LED light is off after about
10 seconds and it indicates that the calibration of empty level is OK.
4.2.3. Calibration completion
Disconnect the calibrator after calibration is done. Connect Pin 1 and Pin 3 on sensor with power, calibration becomes effective when
sensor is power on.
Note: If press the wrong button during operation, you can switch off the calibrator and exit the mode and readjust.
When calibration of the full level and empty level is done, inspect the output signal of the sensor:
If the output signal meets the values listed above, it means calibration is OK and normal operation of the sensor. Otherwise, please check
the mode of connection and recalibrate it.
