Strain Gauges are an essential part of a variety of research and industrial applications because of their incredible ability to measure small amounts of strain on materials over a large range of frequencies. This article seeks to explain the application field and working principle of the MMF022390 model of Strain Gauge from Murata.

Functional Principle

Strain Gauges measure strain indirectly through the variations in resistance caused by stretching, twisting, and compression of the material under test. MMF022390 Strain Gauge consists of two components: a bonded metal foil with a non-conducting substrate. The bonded metal foil is composed of two parts: one is a reacting element which forms a conductive bridge, and the second part is an insulating gap. These two components are connected in series in order to minimize the effects of environmental noise and increase the signal to noise ratio.

When a force is applied to the material under test, the amount of strain produced is directly proportional to the resistance variation in the sensing element of the Strain Gauge. The resistance variation is then detected by the Wheatstone bridge circuit, and the corresponding strain can be calculated from the output voltage or current signal.

Features and Benefits

The MMF022390 Strain Gauge has many features that make it the ideal solution for a wide range of industrial and research applications. Firstly, this model features a very high linearity of 0.01%, which allows for accurate measurement of strain in most types of materials. The linearity also ensures that even small changes in strain will be accurately detected. Secondly, this Strain Gauge has a wide operating temperature range of -55 to +125 degrees Celsius, which makes it suitable for use in harsh environmental conditions. Finally, the small size of the MMF022390 also makes it easy to integrate into existing systems and allows for size optimized design of the sensor.

Application Fields

In addition to its various features, the MMF022390 Strain Gauge also has a wide range of applications. The most common applications for this model are the testing of materials in research laboratories, industrial process monitoring, and as a force sensor in electronic weighing scales. This model also finds applications in medical research and biomedical engineering due to its accuracy and small size.

In conclusion, the MMF022390 Strain Gauge from Murata is an excellent solution for a wide range of industrial and research applications. It provides accurate measurement of strain over a wide range of frequencies and temperatures, and is also small in size. This makes it the ideal solution for those looking for an accurate strain measurement instrument.
