Sensor 260-2180 for hydraulic pump of Carter excavator

1. Sensor: A device or device that can sense the specified measured signals and convert them into usable output signals according to certain rules. It usually consists of sensitive elements and conversion elements.

① Sensitive element refers to the part of the sensor that can be measured directly (or in response).

② Conversion element refers to the part of the sensor that can be sensed (or responded) by a more sensitive element and converted into an electrical signal that is transmitted and/or measured.

③ When the output is a specified standard signal, it is called a transmitter.

2. Measurement range: the range of measured values within the allowable error limit.

3. Range: Algebraic difference between the upper limit and the lower limit of the measuring range.

4. Accuracy: the degree of consistency between the measured results and the true values.

5. Renaturation: the degree of coincidence between the results of continuous measurement of the same measured quantity for many times under all the following conditions:

6. Resolution: the smallest variation that can be detected by the sensor in the specified measuring range circle.

7. Threshold: the minimum measured variation that can make the sensor output produce measurable variation.

8. Zero position: a state that minimizes the absolute value of the output, such as a balanced state.

9. Excitation: External energy (voltage or current) applied to make the sensor work normally.

10. Maximum excitation: the maximum excitation voltage or current that can be applied to the sensor under local conditions.

11. Input impedance: the impedance measured at the input end of the sensor when the output end is short-circuited.

12. Output: The electric quantity generated by the sensor is a function of the external measurement.

13. Output impedance: the impedance measured at the output of the sensor when the input is short-circuited.

14. Zero output: the output of the sensor when the added value is measured to be zero under the local conditions.

15. Lag: The maximum difference in output when the measured value increases and decreases within the specified range.

16. Delay: the time delay of the change of output signal relative to the change of input signal.

17. Drift: In a certain time interval, the sensor output is finally measured by an irrelevant and unnecessary change.

18. Zero drift: the change of zero output at a specified time interval and indoor conditions.

19. Sensitivity: the ratio of the increment of sensor output to the corresponding increment of input.

20. Sensitivity drift: the change of the slope of the calibration curve due to the change of sensitivity.

21. Thermal sensitivity drift: sensitivity drift caused by sensitivity change.

22. Thermal zero drift: zero drift caused by changes in ambient temperature.

23. Linearity: the degree to which the calibration curve is consistent with a specified limit.

24. Philippine linearity: the degree to which the calibration curve deviates from a specified straight line.

25. Long-term stability: the ability of the sensor to remain within the allowable error within the specified time.

26. Inherent yield: when there is no resistance, the free oscillation yield of the sensor (without external force).

27. Response: the characteristics of the measured change at the time of output.

28. Compensation temperature range: the temperature range compensated by keeping the sensor in the range and zero balance within the specified limit.

29. Creep: When the environmental conditions of the measured machine remain constant, the output changes within the specified time.

30. Insulation resistance: Unless otherwise specified, it refers to the resistance value measured between the specified insulation parts of the sensor when the specified DC voltage is applied at room temperature.
