Strain gauges are devices used to measure the strain created on an object due to an applied external force. One of the most widely used strain gauges is the MMF326986, which is manufactured by Vishay Precision Group. The MMF326986 strain gauge is commonly used in measuring deformation in civil engineering structures, such as bridges, towers, and dams. This strain gauge is also used in industrial applications for measuring strain in machine parts, such as bolts, gears, and shafts, and in electronics for measuring strain on printed circuit boards and flexible printed circuit boards.

The MMF326986 strain gauge has a Wheatstone bridge circuit configuration. The strain gauge consists of a sensing element comprised of a metal foil pattern sensitive to strain. The foil pattern is composed of four strain gauges arranged in a Wheatstone bridge configuration. The metal foil pattern is bonded to the surface of the object being measured.

The resistance in the foil pattern changes when the object is subjected to an external force, causing the deflection and strain. The amount of strain is determined by measuring the change in resistance of the foil pattern. The change in resistance is measured using a Wheatstone bridge circuit. This circuit is composed of four resistors arranged in a square pattern. When the bridge is balanced, the resistance of each resistor is equal. When the strain is applied, the resistance of the foil pattern changes, causing the balance of the bridge to be upset.

The Wheatstone bridge provides four active output terminals to indicate the change in resistance of the strain gauge. These outputs can be connected to a differential amplifier circuit which has the capability to measure small changes in resistance. The amplifier circuit provides a single output voltage proportional to the amount of strain applied to the sample.

The MMF326986 strain gauge is sensitive to strain values ranging from 0 to 3000μΩ. It has an extremely low temperature coefficient of resistance, and therefore can be used to measure strain at extremely low temperatures. It is also relatively insensitive to vibration and has an excellent signal-to-noise ratio. The strain gauge is constructed from a polymer material which gives it a high degree of protection against mechanical damage.

The MMF326986 strain gauge can be used to measure small changes in strain over a wide temperature range. It is widely used in many applications due to its excellent performance. The strain gauge is particularly useful in applications that require the measurement of small changes in strain due to its excellent signal-to-noise ratio. It is also used in applications that require the measurement of strain in low-temperature environments due to its low temperature coefficient of resistance.

In conclusion, the MMF326986 strain gauge provides an effective and efficient means of measuring strain on an object. The strain gauge is widely used in a variety of applications due to its excellent performance and low temperature coefficient of resistance. It is also relatively insensitive to mechanical damage due to its construction from a polymer material. The strain gauge provides an active output which can be connected to a differential amplifier circuit, allowing the amount of strain on an object to be accurately measured.
