Pressure Sensors & Transducers

The PPT0100DWF2VA is a unique device that falls into the realm of pressure sensors and transducers. This device is computer-programmable and allows for communications via the CAN bus or LINbus protocol. It has the ability to measure absolute pressure independently or relative to atmospheric pressure, which can be useful in certain applications. Additionally, the PPT0100DWF2VA has high accuracy and a wide bandgap. The temperature sensor element and thermal protection built into the device makes it suitable for use in automation processes. It also has a reset and delay feature that further increases its effectiveness in industrial and automotive applications.

Application Field

The PPT0100DWF2VA can be widely used for automotive applications, such as monitoring the pressure of coolant, oil, brake fluid, and air in engines and transmission systems. Moreover, this device can also be used in industrial applications, like monitoring and controlling the pressure of air, steam, gas, and chemical liquids. Other general uses for this device include, but are not limited to, measuring and controlling the pressure in compressed air systems for medical applications, measuring barometric pressure, and measuring relative and absolute pressure in laboratories.

Working Principle

The PPT0100DWF2VA uses a diaphragm transducer to measure pressure. This transducer consists of a diaphragm, a strain gauge bridge, and a Wheatstone bridge. The diaphragm is a flexible membrane that is attached to the end of the casing. Pressure is applied to the diaphragm, which then deforms. This deformation changes the electrical resistance of the strain gauge bridge, resulting in a change in voltage or current. The change in voltage or current is then measured by the Wheatstone bridge, which is connected to an A/D converter, thereby allowing for digital readouts of pressure. This digital readout, in turn, is then transferred to a PC or embedded controller using CAN bus or LINbus protocol.

Conclusion

The PPT0100DWF2VA is a unique device that effectively combines computer-programmable capability with pressure sensing and transducing capabilities. While its primary application field is within the automotive and industrial sectors, it can also be used for a variety of other uses. Its working principle involves the use of a strain gauge bridge and Wheatstone bridge to measure and convert the changes in electrical resistance caused by the deformation of a diaphragm. Broadly speaking, the PPT0100DWF2VA is a highly versatile device capable of meeting the needs of a wide variety of applications.
