Features

Shear/Torque Strain Gages are for measuring shear strain and torque, typical applications are for measurements on torsion bars and determining shear stresses in shear beam load cells.

M Series strain gauges have been specially developed for high resistance to alternating loads at increased strain levels and high temperatures up to 300°C (572°F). They are foil strain gauges with measuring grids made of a special nickel-chromium alloy. OMEGA/HBM offer this special strain gauge with various geometries, measuring grid lengths and temperature response matching.

New materials offering high strength such as fiber composites pose a major challenge for strain gauges used for measurements specifically when pushing components to their mechanical limit of performance. Situations may arise where a strain gauge subjected to alternating loads at increased load levels is weakened and fails earlier than the component under test. The M Series has been specially developed for high resistance to alternating loads and allows for testing of materials featuring high strength.

All M Series strain gauge types are available with different measuring grid lengths:
• 1.5 mm: where space is a constraint or when highly selective measurement results are required
• 3 mm: for inhom*ogeneous materials and where space is a requirement or not
• 6 mm: for inhom*ogeneous materials and where space is not a requirement

The right measuring grid length: The measuring grid length depends on the aim of measurement, since the result of a measurement with strain gauges will be determined as the average of strains. In general, measuring grid lengths of 3 to 6 mm (0.06 to 0.24') generates a better result.

Long measuring grids are recommended where there is an inhom*ogeneous material such as concrete or wood. A long strain gauge will bridge the inhom*ogeneity of the work piece and return the strain underneath the measuring grid as the measurement result.

Short measuring grids are suitable for detecting a local strain state. Therefore, they are suitable for determining strain gradients, the maximum point of notch stresses and similar stresses.

FAQs

What is the strain gauge for high-temperature applications? ›

ZC-Series strain gages are expertly designed for high-temperature applications up to 2100°F (1150°C). These gages are etched Kanthal (Fe-Cr-Al alloy) foil grids in free-filament form.

What is the maximum temperature for a strain gauge? ›

Strain gauges covering the range 200ºC to 1325ºC offering strain gauges in a variety of configurations and mounting methods. Foil strain gauges can be supplied for up to 700ºC and wire gauges are used up to and sometimes beyond 1350ºC.

Does temperature affect strain gauges? ›

Temperature-related effects are one of the most common causes of measurement error with strain gages.

What strain gauge is used to measure temperature? ›

Most are attached directly to the object with an adhesive. Strain gauges for room temperature can measure up to +80℃. For adhered high-temperature applications, the temperature can be up to +350℃. * At higher temperatures, some are attached by electric welding and can measure up to +800℃.

What are the limitations of strain gauge? ›

Limited Measurement Range: Each strain gauge has a specific measurement range, beyond which it may not provide accurate readings. This limitation restricts their application in cases where high strains are expected, such as during dynamic load testing or extreme events like earthquakes.

What is a high temperature gauge? ›

If your temperature gauge reads hot, there's a possibility that your engine is overheating. Another reason it might be high is that you have a coolant leak (that could lead to engine overheating). A minor leak should be diagnosed and patched up by an auto professional.

What can a strain gauge not be used to measure? ›

So the device can not be used to measure pressure. Strain guage: A Strain gauge (sometimes referred to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured.

What is the ideal strain gauge? ›

Karma strain gauges are also suggested for static strain measurement over a wide temperature range from -75 to 200°C (-100 to 392°F) due to its good linearity over this wide temperature range. Karma strain gauges are often used for fatigue-rated transducer designs.

Do strain gauges need to be calibrated? ›

For strain gauges, calibration is essential to determine the sensitivity or gauge factor of the device, which is the ratio of the change in electrical resistance to the change in strain.

What is the problem with strain gauges? ›

Problem #1: Low-Quality Manufacturing or Construction

Small mechanical changes within the strain gauge are responsible for changes in voltage, which creates the reading on the scale. If flaws in the strain gauge's construction prevent the material inside from moving properly, the reading will not be correct.

How can a technician compensate for temperature in a strain gauge? ›

Use self-compensated strain gauges

Use a Wheatstone bridge circuit with a three or four wire circuit. Use a carrier-frequency amplifier to exclude thermoelectric voltages. For computational compensation: Perform a parallel temperature measurement.

Do strain gauges wear out? ›

Absolute Strain

When the specified limit is exceeded, the strain gauge is damaged with high probability.

How accurate are strain gauges? ›

Measurement Accuracy

Accuracies of 0.5% to 1% are typical for strain gages with a measurement limit of up to 5% strain (50,000 µε).

What is the range of strain gauges? ›

Strain gage resistance

The resistance of a strain gage is defined as the electrical resistance measured between the two metal ribbons or contact areas intended for the connection of measurement cables. The range comprises strain gages with a nominal resistance of 120, 350, 600, and 700 Ohms.

What is the strain gauge theory? ›

What is the working principle of Strain Gauge? A strain gauge works on the principle of electrical conductance and its dependence on the conductor's geometry. Whenever a conductor is stretched within the limits of its elasticity, it doesn't break but, gets narrower and longer.

What are the applications of strain gauges? ›

These strain gages are tailored for force, torque, pressure and displacement measurements within industrial, medical, aerospace and consumer industries. Applications range from medical devices, smart phones, commercial scales, tank and vessel weighing, web-tension and bathroom scales.

What is temperature stress strain? ›

Thermal stress is developed when the material is not allowed to expand or contract freely with the increase or decrease in temperature. The corresponding developed in this case is called thermal strain. Stress and strain of a material are both correlated with one another using the Young's Modulus.

What is high temperature testing? ›

MIL-STD 810 high temperature testing helps evaluate the effects of high temperature conditions on performance, integrity, and material safety. This method is best used on material likely to be deployed where temperatures are higher than standard ambient.
