Pressure sensing or transduction is the process of using a standard of known pressure to measure a device\'s true pressure. M7139-020BG-200000 is a pressure sensor/transducer that can be used in a wide range of industries to take pressure measurements and accurately convert them into an electrical signal output for control or monitoring purposes. It has a range of up to 200,000 PSI (pounds per square inch) of pressure, with a response time less than 10 mS. The device has applications in industries such as vehicle control systems, medical equipment, aerospace, and process control.

Basic Operating Principle

The M7139-020BG-200000 uses the same basic principle as other pressure transducers. This includes sensing the pressure applied to a diaphragm and converting it into an electrical signal via Wheatstone Bridge technology. A Wheatstone Bridge is an electrical circuit composed of four resistors, each of which is connected to a strain gage. When pressure is applied to the diaphragm, the strain gage arrangement deforms, thus changing the structure of the bridge. This in turn changes the resistance to the flow of electrical current. The amount of current can then be measured and used to calculate the approximate pressure applied to the diaphragm. The bridge is created from a combination of four strain gages that are bonded to the diaphragm, along with discrete components to form a Wheatstone Bridge.

Applications

The M7139-020BG-200000 has a range of up to 200,000 PSI (pounds per square inch) of pressure. It is a rugged, reliable pressure sensor/transducer designed to deliver accuracy over a wide temperature range (14°F to 122°F [-10°C to 50°C]), and it can measure very low variations in pressure, making it one of the most sensitive and reliable pressure transducers available. This makes it ideal for a number of industries, such as vehicle control systems, medical equipment, aerospace, and process control.

In vehicle control systems, the M7139-020BG-200000 can be used to measure engine temperatures, depressions in the suspension, and pressures in the fuel lines. In medical equipment, the device can be used to monitor air pressure in respirators as well as the pulsatile pressure within the heart pump. In process control, it can be utilized for leak checking, controlling factory processes, and ensuring gas mixtures within production lines are maintained accurately. In aerospace, the transducer can be utilized for fuel system pressure monitoring, fluid lines, and altitude control.

Conclusion

The M7139-020BG-200000 is an impressively sensitive pressure transducer/sensor that can be used in a multitude of industries to accurately measure and monitor pressure. Its rugged and reliable design make it well suited to a range of environments, and its wide temperature range allow it to stay accurate while monitoring temperatures in different climates. Its Wheatstone Bridge technology accurately measures pressure changes and translates them into an electrical current, and its fast response times mean it is a reliable and efficient means of managing and controlling pressure systems. Although it is not the only pressure sensor/transducer available, its impressive range of 200,000 PSI of pressure, combined with its accuracy and reliability, make it one of the best sensors available.
