Drill mounting hole First of all, clean up the residual oil in the tank and flush it with water. Select the drilling point on the centered surface of the tank and consider whether it will conflict with the components inside the tank. Use the hole cutter at the selected drilling point. Drill a fixed point, start drilling, avoid the iron filings entering the tank when drilling; when the center hole is finished, select a smaller drill bit to process the fixing hole according to the hole position of the sensor gasket; Sensor truncation First, measure the internal height of the fuel tank and obtain the value H; set the internal height of the tank H - 10mm = L (L is the height from the lower end of the sensor flange to the bottom); according to the obtained L value, use a hacksaw to saw the excess part After sawing, use guillotine to clear the fines on the end face, keep the end face flat and clean, and at the same time clean out the aluminum chips between the inner and outer tubes, and re-screwed the bottom terminals with screws. At this time, the cutting step ends; Calibration 1. When the sensor is cut off, it must be recalibrated; 2. The calibration process is only related to the immersion level and the immersion medium, and has nothing to do with the volume of the fuel tank; Analog output calibration method Before the calibration of the sensor, please make sure that the sensor is connected with the handheld calibrator (the description of the handheld calibrator is shown in Appendix 1), and turn on the calibrator power switch; at the same time, prepare a number of measurement media (the depth of the container should be greater than the sensor range Can be); The sensor is fixed, the bottom of the sensor is immersed in the height of the liquid height set by the customer, and allowed to stand for 10 seconds, press the calibrator zero calibration button, when the lamp flashes, indicating that the zero calibration is successful, then output 0V Or 4mA (ie zero output); similar to step 2, the sensor immersed in the height and the customer's full-scale height of the liquid corresponding to the set, stand for 10 seconds, press the calibration button full-scale calibration, when the light flashes, Said full-scale calibration is successful, then output 5V or 10V, 20mA (that is, full-scale output); when the zero and full-scale calibration is successful, the handheld sensor can move up and down the liquid level, you can see the display instrument with the liquid level changes accordingly The change. Abnormal description: When the sensor continuously outputs 2.5V or 5V or 12mA, it means that the calibration of the sensor is abnormal; calibration is required after power off and restart. Digital output calibration method Before the calibration of the sensor, please make sure that the sensor is connected to the power supply, and connect the digital output line to the computer through the adapter and open the test software (see the software operation documentation for related methods of use); Connect the bottom of the properly connected sensor to the required zero position, let it rest for 10 seconds, and the operating software records the zero value; In the same step 2, the sensor is immersed in the required full position, and it is allowed to stand for 10 seconds. The operating software records the zero value. According to the software's operation procedure, the calibration is successful. Open the display interface, you can see that the data of the display interface will change with the height of the sensor immersed; Abnormal description: When the software shows that the calibration is unsuccessful, it must be calibrated again after power off and restart. Fixed installation When the calibration process is completed normally, the sensor can be installed on the tank; at this time, the sensor can be fixed on the tank through self-tapping screws, and the installation process is completed; Handheld calibrator use method: 1. Connect the connector of the hand-held calibrator to the output connector of the sensor, and toggle the switch on the right side to ON. At this time, the POWER lamp lights up; 2. At this time, the zero position of the sensor is immersed and leveled with the liquid level. When the liquid level is stable, press the EMPTY button. After about two seconds, the SET light will flash once, indicating that the zero calibration is successful. 3, as above, the sensor's full position immersed in liquid level with the liquid, until the liquid surface is stable, press the FULL button, about two seconds later, the SET light will flash once, indicating that the full calibration is successful; 4. At this time, remove the calibrator connector and replace it with the sensor outlet. Note: This calibration process needs to be completed together. Do not power off during the process. If the calibration output is abnormal, follow the steps to recalibrate.
