Pressure sensors come in a variety of shapes and sizes, however the most common type is the P61-750-A-A-I72-4.5V-C series. They are designed to measure absolute or gauge pressure ranging from 0-750mbar (±15mbar). The most advantageous feature of the series is the fact that it is based off the patented I72 strain gauge technology that is capable of providing an accurate measurement even when subjected to dynamic and static pressure change. The sensing element of the P61-750-A-A-I72-4.5V-C pressure sensor is made up of a full bridge of strain gauge resistors. It uses two connecting leads, one positive and one negative, and is interfaced to an external circuit for measurement.

The P61-750-A-A-I72-4.5V-C series of pressure sensors are mainly used for industrial applications in the fields of automotive, aerospace, engineering and marine. They can be used for monitoring petrol and diesel engines, hydraulic and pneumatic systems, liquid level measurement, flow control and air pressure systems. They are also suitable for measuring liquid pressure, gas pressures and vacuum application.

The P61-750-A-A-I72-4.5V-C series of pressure sensor comes with an integrated amplifier which amplifies the gauge output to 4.5V. The amplifier helps in providing a linear output for the entire range of pressure from 0-750mbar. It also provides a temperature compensation from 0-90°C, which helps in increased accuracy of the signal. The sensor also features sensitivity settings of 0-750 mV/V, which helps to provide higher response time and accuracy when used on applications that require accurate monitoring of pressure.

The working principle of the P61-750-A-A-I72-4.5V-C series of pressure sensor is based on the principle of electrical resistance variation when there is a strain on the sensing element. The sensing element has four strain gauge resistors arranged in a full bridge configuration. When there is a pressure applied on the sensing element it creates a strain which causes the electrical resistance values of the strain gauge resistors to vary. The bridge output voltage is calculated by measuring the voltage drop at each resistor. The amount of strain is then proportional to the applied pressure. The amplified output of the bridge circuit provides a ±4.5V output in response to the applied pressure.

The P61-750-A-A-I72-4.5V-C series of pressure sensor is a great choice for applications in industries that require a highly accurate pressure measurement. They are easy to install, user friendly and require minimal maintenance. The built-in amplifier helps in measuring a wide range of pressures and can handle dynamic and static pressure changes. The temperature compensation feature ensures the accuracy of the signal even in high-temperature conditions. It can be used for a variety of applications, from monitoring petrol and diesel engines to measuring liquid level and air pressure.
