Pressure Sensors, Transducers:

P51-50-A-H-MD-5V-000-000 is a type of pressure sensor or transducer which converts an input pressure to a signal that corresponds to the pressure measurement. The sensor uses a strain gage-based pressure sensing element and an amplifier circuit to gain accuracy and stability on the analog output. Other versions of this pressure transducer are available with different mechanical construction and electrical configurations.

Application Field:

The P51-50-A-H-MD-5V-000-000 is mostly used when monitoring pressure in fuel-related systems, such as fuel pumps, injectors, and fuel tanks. It is also used in water and wastewater applications including pumps, traps, and tanks. This pressure sensor is also used in automotive industries in order to detect and control the fuel pressure in engines.

Working Principle:

The working principle of the P51-50-A-H-MD-5V-000-000 is based on Wheatstone bridge circuit with a strain gage-based pressure sensing element. The strain gage is a conductive element, allowing a current to flow through it when balanced. When force, such as pressure, is applied to the gage, its resistance and resultant current flow changes. This transforms the physical property (force) into an electrical signal (voltage). It is then amplified by an amplifier IC, filtered, and sent to the output terminal.

The pressure detected by the strain gage is mathematically proportional to the output voltage signal. As an example, a P51-50-A-H-MD-5V-000-000 with a full-scale range of 0-150 PSI would produce 0 V output for 0 PSI and 4-5 V output for Maximum of 150 PSI.

This type of pressure transducer is made up of an outer housing with an internal transducer diaphragm, an inner body, a gasket, an electrical connector, a fill fluid, and a silicone gel or epoxy adhesive. The outside housing contains the pressure sensing element while the inner body contains the amplifier circuit. The connection between the pressure sensing element and the amplifier circuit is electrical in nature.

The pressure sensing element is composed of a metal diaphragm and an electro-resistance strain gage, which converts the applied pressure into a change in resistance. The amplifier circuit is responsible for amplifying the output of the strain gage and provides the user with a voltage signal proportional to the pressure. In some cases, the amplifier circuit may also contain other features, such as temperature compensation.

The P51-50-A-H-MD-5V-000-000 is available in different mechanical forms. Some versions are available with a pre-assembled electrical connector and/or mating connector, which can make connection and installation much easier. This type of pressure sensor is also available in various pressure ranges and output signals.

The P51-50-A-H-MD-5V-000-000 is commonly used in a variety of applications including industrial automation, automotive, aerospace and military, and medical equipment. This type of pressure transducer is well-suited for applications where accuracy and repeatability of measurements are essential, such as pressure measurements in fluid systems.
