The PC404A-202R is a multipoint intelligent pressure sensor board. It is a complete analog electronics board composed of sensors, plug-and-play hardware, and associated software for easy integration into a variety of applications, including industrial, medical, and automotive. The PC404A-202R is designed for use in embedded systems and as an expansion board for development platforms.

The PC404A-202R is a very important component of any industrial system as it provides temperature, pressure, and flow measurement capabilities. It is also able to measure a wide range of pressures, from a few millibar up to 1500Bar. Moreover, the PC404A-202R is designed to be compatible with multiple communication protocols, including CAN bus, Modbus, and EtherCAT.

The PC404A-202R application field mainly includes automotive and industrial applications. It has been traditionally used in the automotive industry for various applications such as engine control systems, brake system pressure monitoring, and fuel tank pressure monitoring. In industrial applications, it is used for monitoring environmental conditions such as temperature and humidity, and for monitoring pressure, flow, and other parameters in chemical processes and pipelines.

The PC404A-202R working principle is based on the Wheatstone bridge principle, which measures the change in electrical resistance in response to a change in the applied pressure. The Wheatstone bridge consists of two resistive electrodes, one of which is connected to the applied pressure and the other is connected to a reference pressure. When the applied pressure changes, the resistivity of the electrodes changes and creates a changing electrical potential. This potential is then amplified and converted to a voltage level that can be measured and used as an indication of the applied pressure.

In addition to the Wheatstone bridge, the PC404A-202R also uses a temperature sensor and a calibration pressure sensor. The temperature sensor is used to compensate for any temperature induced inaccuracies in the measurement, while the calibration pressure sensor is used to set a reference point for the Wheatstone bridge circuit. The data from these sensors is then processed by a microcontroller to provide accurate digital output data on the measured pressure.

With its advanced features such as plug and play compatibility, wide range of pressure measurement capabilities and multiple communication protocols, the PC404A-202R is a great choice for many different applications. Its ability to reliably measure and monitor various parameters makes it an ideal choice for a variety of industrial and automotive applications.
