level sensor directions for use

characteristic

This series of sensor is measuring level measuring instrument, has the very high resolution and accuracy of measurement. It without human intervention, automatic calibration, does not exist temperature drift, and could not be affected by changes in the media. That is with a sensor, no matter be measured medium is water or gasoline or diesel, no matter how the temperature changes, it can correct output level highly accurate signal. Thoroughly solved the ethanol and gasoline, methanol fuel, and other media difficult the problem of measurement, and it solves the different areas for oil different and temperature of the label huge differences of the measurement error problem. At present the technology in China is unique, in international leading level.


Agreement two:

Inquires the command: * # 020600

Reply: $XROIL0202DDDDXX \ n DDDD value for oil, XX for different or calibration value, '\ n' end operator

DDDD for oil a percentage

For example: $XROIL02025678XX \ n

Oil is a percentage is 56.78%. Read the current level percentage * # 020600

Damping coefficient * 0206 X3 # x for 0-9 (0 without damping, 9 maximum time ditto)


1, RS232 / TX485 / 0-5V / 4 ~ 20mA signal can only exist one, you can choose to use one of them. TX485 bus can simultaneously access multiple sensors, but in advance to set the communication address of each sensor, each sensor's communication address must be unique to prevent the bus lock. RS485 bus is a half-duplex chip, so read the data should be given to the module to respond to the time, read the speed can not be too fast, continuous reading when the time between the two instructions can not be less than 200ms.

2, due to poor vehicle environment, the sensor power supply to be isolated power supply. Signal transmission line, especially RS232 communication, communication line should not be too long, and should be shielded.

3, the RS232 / TX485 signal sensor, in the exclusion of communication failure, the blue and yellow line can be adjusted to test, if the communication is successful, it is caused by wiring errors. This operation is limited to digital communication.

4, the sensor supply voltage shall not exceed its normal operating voltage, and the sensor power supply power consumption is not less than the normal use of the sensor power consumption.

5, the actual environment should meet the basic parameters of the sensor requirements, not beyond the normal range, otherwise it will lead to damage to the sensor, and even cause other accidents.

6, the sensor output is the height of the measured medium signal, in the case of zero filter, the output value of the composition of the curve of the actual changes in oil surface, the output value with the oil surface rise or fall and change, plus The filtered curve will become smooth, the larger the filter value, the smoother the curve, but the amount of oil will lag behind the change in the amount of time. Therefore, the smoothness of the curve is proportional to the lag time (reaction time) of the oil value. The factory filter value is a more appropriate value set for comprehensive customer feedback and field conditions.

7, due to the relationship between the oil, the sensor set the media and the use of the media there is a certain difference, the sensor has a function of automatically adapt to a variety of media, can be resolved due to different media errors, so the user should be used before 2.2 in the operation.

8, do not disassemble the sensor or malicious damage, or will not warranty.

9, the conventional sensor factory attachment rubber pad, set screws, brochures, certificates and other accessories, if any special requirements, please be given in advance to say.
