Pressure sensors, transducers and other instruments are widely used in the power, construction, home appliance, automotive and many other industries. Pressure sensors, transducers and other instruments are designed to detect and measure pressure in various mediums such as liquids, gases and solids. Understanding the working principle behind these instruments is essential for designing a solution tailored to a customer’s needs.

P51-50-S-AA-D-4.5V-000-000 is a pressure sensor which is widely used in these industries. It is a two-wire DC Strain Gauge based pressure sensor. It has various applications ranging from oil and gas wells, residential boilers, and industrial processes.

P51-50-S-AA-D-4.5V-000-000 has a 4.5v DC excitation voltage and can be used for high temperature applications. It is a full bridge type pressure sensor which uses a Wheatstone bridge circuit. It is strain gauge based and produces an output voltage proportional to the amount of pressure applied to the diaphragm. This voltage is generally between 0-18mV.

The Wheatstone Bridge is the primary principle used by the pressure transducer. When pressure is applied on the diaphragm, it causes a mechanical strain, which in turn causes a change in the resistances of the strain gauges. This affects the balance of the bridge, creating an output voltage that is proportional to the applied pressure. The Wheatstone Bridge consists of four resistors, positioned in the shape of a diamond, with the pressure transducer’s strain gauges connected to two of the resistors. When the pressure on the diaphragm changes, it causes strain on the strain gauges and causes an imbalance between the two legs of the bridge. This imbalance creates an output voltage proportional to the applied pressure.

The sensing technology used in this pressure sensor is capacitive. The capacitive sensing technology provides a more consistent output voltage, which is better suited for precision applications. It is also the most commonly used technology in industrial pressure transducers. This transducer is also highly accurate and produces a very linear output signal over its operating range. It has a wide temperature range (-50 °C to +100 °C) and a high over-pressure capability of 500 psi (4.5 times full-scale) which suites it to a wide range of applications.
