The HA Series Foil Strain Gauge is a high-performance sensing solution designed for precise strain measurement in a variety of industrial and research applications. Manufactured using premium metal foil materials, this strain gauge offers exceptional accuracy and reliability, making it an ideal choice for engineers and technicians who demand consistent and repeatable results. The HA Series is available in configurations suitable for Half Bridge Strain Gauges and Full Bridge Strain Gauge setups, providing flexibility to meet diverse measurement requirements.
One of the standout features of the HA Series Foil Strain Gauge is its minimal creep characteristic, rated at ±0.05% Full Scale. Creep, the tendency of the strain gauge output to drift under a constant load over time, is a critical parameter in long-term strain measurement applications. The exceptionally low creep value of this product ensures that measurements remain stable and accurate even during extended testing periods, thereby enhancing the reliability of data collected in structural monitoring, material testing, and other precision engineering tasks.
The HA Series strain gauge is constructed with a choice of carrier materials, including Phenolic Aldehyde, Polyimide, and Epoxy. These carrier materials are carefully selected to provide optimal mechanical support and environmental protection to the metal foil sensing element. Phenolic Aldehyde offers excellent rigidity and thermal stability, making it suitable for applications where dimensional stability is paramount. Polyimide carriers are known for their flexibility and high-temperature resistance, ideal for dynamic testing environments. Epoxy carriers provide robust adhesion and chemical resistance, ensuring durability in harsh conditions. This versatility in carrier material choice allows users to select a strain gauge that best fits their specific operational demands.
The metal foil material used in the HA Series is engineered for superior performance in strain measurement. Metal foil strain gauges are recognized for their high sensitivity, low temperature coefficient, and fine resolution, enabling the detection of minute strain variations. The foil construction also contributes to excellent linearity and repeatability, critical factors when integrating Half Bridge Strain Gauges or Full Bridge Strain Gauge configurations in complex measurement systems.
Another key attribute of the HA Series is its minimal hysteresis, rated at ±0.05% Full Scale. Hysteresis, the difference in output when a strain gauge is loaded and then unloaded, affects the accuracy of strain measurement during cyclic loading. The low hysteresis of this product ensures that the electrical output closely follows the actual strain, reducing measurement errors and improving the fidelity of data during repeated stress cycles. This makes the HA Series particularly suitable for fatigue testing and structural health monitoring where cyclic loading is common.
The HA Series supports both Half Bridge Strain Gauges and Full Bridge Strain Gauge configurations, which are widely used in strain measurement systems. Half Bridge Strain Gauges typically consist of two active gauges arranged to compensate for temperature effects and improve sensitivity. Full Bridge Strain Gauge setups incorporate four active gauges, offering even greater accuracy, temperature compensation, and signal strength. The HA Series is engineered to seamlessly integrate into these bridge configurations, offering reliable electrical characteristics, easy installation, and compatibility with standard strain gauge instrumentation.
In summary, the HA Series Foil Strain Gauge is a versatile and dependable product that excels in precision strain measurement. Its combination of ultra-low creep and hysteresis, choice of advanced carrier materials, and high-quality metal foil construction make it suitable for a wide range of applications. Whether deployed as Half Bridge Strain Gauges or within a Full Bridge Strain Gauge system, the HA Series delivers consistent performance, durability, and accuracy, providing engineers and researchers with the confidence needed for critical measurement tasks.
