Melt Pressure Sensor Sensitivity And Accuracy
Sensitivity and accuracy of melt pressure sensors are two key characteristics that evaluate the sensors' performance and measurement accuracy. Although these two terms often seem similar, they have different meanings and both help us understand how reliable measurements a sensor can make.
Sensibility:
Sensitivity refers to how accurately a melt pressure sensor can measure within a certain pressure range. That is, sensitivity indicates how close the sensor's output signal is to the true value.
Sensitivity measures the difference between the sensor's output signal and the actual pressure value. This difference is usually expressed as a percentage (%) for a given pressure range.
A sensor with higher sensitivity will give measurement results closer to the true value. This means the sensor can make more accurate measurements.
Truth:
Accuracy refers to how close the measurement results of a melt pressure sensor are to true values. That is, accuracy indicates how reliable the measurement results of the sensor are.
Accuracy measures how closely the sensor can track the actual value and is usually expressed in percentage (%).
A sensor with higher accuracy means its measurements are closer to the true values and provide more reliable results.
Sensitivity and accuracy are critical in evaluating the performance of melt pressure sensors. These properties are determined during calibration and testing of the sensor and are specified by the manufacturer in the specifications. Depending on the application in which the sensor will be used, sensitivity and accuracy requirements may vary. Higher sensitivity and accuracy may require higher cost sensors, so it is important to carefully consider your application requirements.
