Pressure sensors and transducers are devices that measure pressure and convert it into an electric signal. The NPA-100B-10WD is one such device that is well suited for applications in a variety of fields, including automotive, industrial, and medical. In this article, we will take a look at this specific model of pressure sensor and transducer, its application field, and its working principle.

Application Fields

The NPA-100B-10WD has a wide range of applications and is used in many industries. One of the most common uses of this device is in automotive applications, where it is used to measure tire pressure, oil pressure, fuel pressure, and other vital parameters. It is also suitable for industrial applications, such as measuring pressure in piping systems, valve seals, and other hydraulic equipment. Furthermore, its high accuracy and wide temperature range make it ideal for use in medical applications, such as monitoring blood pressure or other vital signs. It can even be used in HVAC applications to measure the pressure in air-conditioning systems.

Working Principle

The NPA-100B-10WD works by sensing pressure and converting it into an electric signal. The device consists of a sensing diaphragm that is made from stainless steel. When a pressure is applied to the diaphragm, it flexes, which causes a strain in the metal. This strain is transferred to a strain gauge, which produces a change in electrical resistance that is proportional to the amount of strain. This change in electrical resistance is then converted into an analog voltage which is transmitted to a connected device for further processing.

The NPA-100B-10WD also features a temperature compensation device, which ensures the accuracy of the measured pressure by adjusting for temperature fluctuations. This temperature compensation device is composed of a temperature sensor, a heating element, and a secondary strain gauge. The temperature sensor senses any changes in temperature and the heating element will cause any changes in temperature to be counteracted by heating the device. The secondary strain gauge then detects this change in temperature, which is used to adjust the electrical resistance so that the device continues to provide accurate and reliable measurements.

Conclusion

The NPA-100B-10WD is a versatile pressure sensor and transducer that is suitable for a variety of applications. It is capable of providing accurate and reliable measurements in automotive, industrial, medical, and HVAC applications. It works by sensing pressure and converting it into an electrical signal, and also features a temperature compensation device to ensure accuracy in even the most extreme conditions. As such, it is an invaluable tool for any engineer who needs to measure pressure with high accuracy.
