Pressure Sensors & Transducers: P51-300-A-AD-MD-4.5V-000-000

Pressure sensors and transducers are electronic devices used to measure and monitor pressure. Common types include strain gage, piezoelectric, and thermocouple-based pressure sensors and transducers. The particular model known as P51-300-A-AD-MD-4.5V-000-000 falls into the strain gage category.

Application Field and Working Principle

Strain gage based pressure sensors and transducers are typically used in industrial applications where pressure needs to be monitored and measured accurately. They are suitable for applications such as fluid level monitoring, pressure mapping, tire pressure monitoring, ventilation control, and even medical applications such as blood pressure monitoring. The working principle behind this type of pressure sensor and transducer is based on monitoring changes in strain in a substrate or diaphragm. The strain gages are typically bonded to the substrate or diaphragm and connected to a Wheatstone bridge circuit. When pressure is applied to the substrate or diaphragm, the strain gages are also affected. This leads to a change in resistance of the strain gages which is reflected on the output voltage of the Wheatstone bridge circuit. The Wheatstone bridge output can be connected to a signal conditioning circuit for further analysis and data acquisition.

The P51-300-A-AD-MD-4.5V-000-000 pressure sensor and transducer model in particular is an OEM model which is used for various applications, including pressure and vacuum measurement, environmental monitoring, and fluid level control. It has a 0.3g measuring range, 4.5V full scale output, 120 mV/V sensitivity, and an inbuilt amplifier to reduce the thermocouple effect. It is also highly accurate and is compatible with various analog amplifiers. In addition, it has a built-in diaphragm for low power consumption and a long life, making it suitable for prolonged and continuous use.

As a result, the P51-300-A-AD-MD-4.5V-000-000 pressure sensor and transducer offers reliability, accuracy, and longevity in a wide variety of applications. It is a valuable tool for many industrial and medical applications that require precise measuring of pressure and normal pressure variations. The strain gage based design also provides a range of benefits, including uniform sensitivity, wide temperature range, and low noise output.
