Pressure Sensors, Transducers

The M5251-000005-05KPG is a pressure sensor or transducer designed for use in a variety of applications. It is specifically designed to measure small changes in pressure and linearity. The transducer has a measurement range from 0 psi to 5 psi and is suitable for use in applications such as industrial process control systems, automotive monitoring systems, process instrumentation, and instrument calibration.

This pressure sensor is designed with a rugged shock and vibration resistant housing, making it highly reliable in harsh industrial environments. It also offers excellent accuracy and stability over its operating temperature range. The transducer operates on a wide temperature range from -20°C to +90°C and has a high accuracy rating of 0.5% FS.

Working Principle

The working principle of the M5251-000005-05KPG pressure sensor is based on the Wheatstone bridge principle. The sensor has four strain gauges encased in the housing simulating a Wheatstone bridge configuration. A change in pressure outside the sensor is converted into small changes in the sensitivity of the strain gauges, resulting in a small voltage output. This output voltage is proportional to the pressure being sensed by the transducer.

The Wheatstone bridge is excited by a constant current source, and the output signal is sent to a differential amplifier. The differential amplifier has a high input impedance to reduce the effects of any external electrical noise. The output is then sent to an analog-to-digital converter, where the output voltage is converted into a digital signal.

The pressure sensor is also equipped with an internal temperature compensation circuit to correct any errors caused due to temperature changes. The temperature compensation ensures that the transducer is highly accurate over its entire operating temperature range.
