Pressure Sensors, Transducers

The P51-50-G-G-P-5V-000-000 is a pressure sensor or transducer used to measure pressure in many areas of application. It’s components include a sensing membrane and spring, housing, electronics and connectors. It is available in many varieties with different pressure and voltage ratings, and has automatic electrical compensation for temperature. Pressure is typically measured in either psi (pounds per square inch) or Bar which is equivalent to 1 atmosphere.

Application Field

P51-50-G-G-P-5V-000-000 pressure transducers are commonly used in industrial and medical applications, such as in HVAC systems to detect low pressure drop, in oil and gas production sites to detect pressure surges, in pipe leak detection systems, in high pressure compressors and pumps, and in medical applications, such as dialysis machines and medical monitoring equipment.

Working Principle

A pressure transducer is essentially a transducer which converts pressure into an electrical signal. It operates on the principle of variable capacitance in a capacitance diaphragm. The sensing membrane and spring have a constant electromagnetic field across them, and any changes in the pressure around them cause a change in the electrical capacitance of the diaphragm. This change is proportional to the change in pressure. The capacitance changes cause displacement of the sensing element which induces a voltage between two signal leads. This voltage is proportional to the change in capacitance, and therefore the pressure.

The pressure transducer is calibrated using external pressure sources, and can also be calibrated to measure absolute or differential pressure. Differential pressure transducers measure the difference between two pressures, such as the pressure at two points in a system or the pressure between the inside and outside of a vehicle. This allows for more precise monitoring and control of the pressure in a system.

The P51-50-G-G-P-5V-000-000 provides a simple, low-cost and accurate way of measuring pressure in many applications. It can be used in a wide range of systems, including medical, industrial, automotive, and many other types of systems.
