Melt Pressure Sensor Sensitivity Test
Sensitivity testing of a melt pressure sensor is performed to evaluate how accurately the sensor measures over a specific pressure range. This test helps determine how close the sensor's output signal is to the actual pressure value. Sensitivity testing may include the following steps:
Preparation of Test Devices:
The pressure measurement equipment required for the test is prepared, calibrated and verified.
The necessary temperature control equipment is set for the test because sensitivity may vary depending on temperature changes.
Determination of Reference Pressure Values:
The required pressure range and reference pressure values for the sensitivity test are determined. These values are chosen depending on the application in which the sensor operates.
Sensor Preparation:
The sensor is connected to the tester and mounted correctly.
The sensor is calibrated and reset if necessary.
Implementation of the Test Procedure:
The test is initiated and a specific pressure level is applied to the sensor.
The output signal of the sensor is recorded.
These steps are repeated within the specified range of reference pressure values.
Saving Data:
The output signal of the sensor is compared with the reference pressure values and the differences are calculated.
The sensitivity value is calculated as the ratio of these differences to the reference pressure values. Precision is usually expressed in percentage (%).
Analysis of Results:
Sensitivity test results show how accurately the sensor measures within a certain pressure range.
Sensitivity test results are used to evaluate the suitability of the sensor for a particular application.
If the sensitivity test results are within certain tolerance limits, the sensitivity of the sensor is considered acceptable.
Sensitivity testing is an important step to evaluate a melt pressure sensor's ability to measure accurately and is necessary to ensure that the sensor can produce reliable results in a particular application. This test is used to determine whether it meets calibration requirements and is important for determining the performance of the sensor.
