MPXV5004G7U

Pressure Sensors, Transducers

The MPXV5004G7U is a high performance pressure sensor developed using Freescale Semiconductor’s advanced high-precision sensing technology. It is designed with differential pressure sensing capabilities, providing accurate measurements up to 5.0 PSI and a full-scale output of 4.7mV/V. The device comes in a small, lightweight package and has been designed with a pressure range that is specifically tailored for port and pressure vessels used in industrial settings. Additionally, the device is able to withstand very high temperature and pressure, and offers a wide temperature range of operation from -40 °C to 125 °C.

The MPXV5004G7U is typically used in applications where accuracy and sensitivity are of the utmost importance. Such applications include industrial process and pressure control, as well as environment monitoring. It can also be used in automotive applications, such as fuel or oil pressure monitoring, and in hydraulic systems, where accurate pressure measurement is required.

The working principle of the MPXV5004G7U is based on a Wheatstone bridge configuration. A Wheatstone bridge, also called a voltage-dividing network, is a circuit consisting of four resistors connected in a distinctive pattern as shown in the diagram below. The resistors are arranged in the form of a square, and the Bridge is activated by applying a potential difference or voltage across the two outside points of the square. This creates a voltage drop across the four resistors, and from this the resistance of each arm of the bridge can be read.

The MPXV5004G7U combines the Wheatstone bridge with a pressure transducer. The device consists of two sensing elements, a pressure-sensing diaphragm and a metal strain gauge. The pressure-sensing diaphragm is linked to the strain gauge, and the strain gauge is connected to the Wheatstone bridge. When a pressure is applied to the diaphragm, it deflects and pushes against the strain gauge. This causes the electrical resistance of the strain gauge to change, resulting in a differential voltage across the Wheatstone bridge. This voltage is then outputted from the bridge and can be read by a suitable instrument.

The MPXV5004G7U is designed to provide very precise measurements in the most demanding industrial environments. It is a robust, reliable device that is easy to install, operate and maintain. Its Wheatstone bridge configuration ensures accuracy and stability, and its pressure range is perfectly suited for use in pressure vessels and other industrial applications.
