DP-102A-J Datasheet/PDFPressure sensors and transducers[1] are one of the four primary dynamic input devices used for data acquisition. The other primary dynamic input devices are temperature, force, and position transducers. Thus, pressure transducers and sensors are used in various applications to measure and convert pressure into a signal that can be processed further by a data acquisition system.
Among the widely used pressure sensors is the DP-102A-J, which offers excellent performance and truly exceptional precision, even under extreme environmental conditions. The DP-102A-J pressure transducer contains a variety of features, such as small size, high temperature rating, and excellent differential pressure and gage pressure measurement accuracies.
Application Field of the DP-102A-J Pressure Transducer
The DP-102A-J can be used to measure pressures ranging from atmospheric up to 7500 psi. It is most often used in mobile hydraulic systems, pneumatic systems, medical fluid monitoring apparatus, general industrial machinery, aerospace systems, and motor race applications. Its piezoresistive sensing element, which is highly temperature compensated, also makes it suitable for use in extreme temperature environments. In addition, the DP-102A-J is particularly useful when accurate pressure measurements require long-term stability and tight accuracy tolerances over a wide operating range.
Working Principle of the DP-102A-J Pressure Transducer
The DP-102A-J pressure transducer uses a modified diaphragm strain-gage bridge, which consists of four piezoresistive strain gages. The gages are arranged in a full Wheatstone bridge, which makes it possible for the transducer to measure pressure through a change in resistance due to the strain induced by the pressure. This makes measurement of very small pressures possible.
The DP-102A-J is temperature compensated to reduce the effect of temperature on the accuracy of the measurements. It utilizes a variable resistor to regulate the bridge balance, and a temperature compensated system is used to minimize the effects of temperature on the resistance of the strain gages. This ensures that the readings from the transducer remain stable and accurate, even in extreme temperature environments.
The DP-102A-J pressure transducer also utilizes reverse polarity protection circuitry to protect the transducer from voltage transients. This ensures that the pressure readings are highly reliable and accurate in even highly robust and dynamic industrial environments.
Conclusion
In conclusion, the DP-102A-J pressure transducer is a highly reliable and accurate device that can be used in a variety of industrial and automotive applications. Its small size, high temperature rating, and excellent pressure measurement accuracies make it an ideal choice for most applications. The temperature compensation feature ensures that the readings remain accurate and reliable, even in extreme temperature environments, and its reverse polarity protection circuitry helps protect the transducer from voltage transients.
