FAQ
Why choose precision pressure gauge?
Gernerally, precision pressure gauges offer higher accuracy and resolution. Therefore, it obtains a smaller granularity in the same range. Due to its excellent performance, it is commonly used in calibration and precision measurement applications. In addition, due to the particularity of sensor selection, the price of precision pressure gauges is more expensive. Therefore, the correct accuracy and resolution for the application is important in choosing a digital pressure gauge, Most industrial processes do not require that level of accuracy, a general pressure gauge is sufficient.
What’s the temperature compensation?
In pressure calibration, the results are always affected by various factors, especially temperature. Under the condition that other factors remain unchanged, the output signal of the pressure sensor will drift with the change of temperature. To ensure the accuracy and reliability of the calibration results, 20 ℃ ± 3 ℃ is the recommended ambient temperature. However, it is difficult to match the desired temperature range in many applications. Therefore, DR3716 is a good solution to meet most scenarios. because the automatic temperature compensation algorithm, it correct calibration result in the full range, and the error is controlled within the allowable range. So This pressure gauge is more widely compatible with more application scenarios.
What is the Response frequency??
Frequency response is a measure of how quickly a pressure sensor responds to changes in pressure. when measure a rapid change pressure, In order to avoid the distortion, you should choose a the high frequency response pressure sensor.
