Wind pressure sensor

A technical brief

Range: Minimum 0~100Pa~0~100Kpa

Power Supply: 24VDC

Output: 4~20mA (two-wire system) 1~5V, 0~5V

Medium: non-conductive non-corrosive or weakly corrosive weak moist gas

Measurement form: positive pressure/negative pressure/differential pressure/bidirectional pressure

Extended recommendation: For lower range differential pressure measurement products

You can choose: micro differential pressure transmitter.

The pressure regulator promotes the use of handheld wind pressure gauges

Second, characteristic description:

1. Sensor: A device or device that can sense a specified measurement and convert it into a usable output signal in accordance with a certain law. There are usually sensitive components and conversion components.

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

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

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

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

3. Range: The algebraic difference between the upper and lower limits of the measurement range.

4. Accuracy: The degree of agreement between the measured result and the true value.

5. Repeatability: The degree of coincidence between the results of multiple consecutive measurements of the same measured quantity under all of the following conditions:

6. Resolution: The minimum amount of change that the sensor may detect in a specified measurement range circle.

7. Threshold: The smallest change that can be measured at the output of the sensor to produce a measurable change.

8. Zero: The state in which the absolute value of the output is minimized, such as equilibrium.

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

10. Maximal stimulus: The maximum value of the excitation voltage or current that can be applied to the sensor under the conditions in the city.

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

12. Output: There is an amount of electricity generated by the sensor that is measured as a function of the function.

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

14. Zero output: In the city conditions, the output of the sensor is added when measured to zero.

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

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

17. Drift: At certain intervals of time, the sensor output is finally measured as unrelated to the unwanted changes.

18. Zero drift: Changes at specified time intervals and at zero output in indoor conditions.

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

20. Sensitivity drift: Changes in the slope of the calibration curve due to changes in sensitivity.

21. Thermal Sensitivity Drift: Sensitivity drift due to changes in sensitivity.

22. Thermal zero drift: Zero drift due to ambient temperature changes.

23. Linearity: The extent to which the calibration curve is consistent with a provision.

24. Nonlinearity: The degree to which the calibration curve deviates from a specified straight line.

25. Long-term stability: The sensor can still maintain the ability to not exceed the allowable error within the specified time.

26. Inherent basis: The sensor's free (without external force) oscillating rate when there is no resistance.

27. Response: Characteristics of measured changes at the time of output.

28. Compensating temperature range: The temperature range that compensates the sensor by keeping the range and the zero balance within the specified limits.

29. Creep: When the measured machine has more than constant environmental conditions, the output changes in the specified time.

30. Insulation resistance: In the absence of other provisions, the resistance value measured between the insulation parts of the sensor when the specified DC voltage is applied at room temperature.
