Durham Instruments strain sensors guarantee reliability, remote power

HBM strain sensors, available from Durham Instruments

Among the high-quality industrial measuring tools that Durham Instruments distributes in Canada are HBM’s lines of software, strain gauges, display and panel meters, and much more. Now, the manufacturer has come up with two designs of Fiber Bragg Grating-based strain sensors that achieve new high standards of performance and versatility.

Useful for various applications

HBM has just released the FiberSensing FS62 Strain Sensor and the FS62 Athermal Strain Sensor, both of which are innovative means of strain measurement in work applications.

The HBM FiberSensing FS62 Strain Sensor is built to be bonded to surfaces, spot-welded to structures or components, or attached to concrete wet mix. Among the many strain-measuring applications for which this sensor is suitable is structuring health monitoring in large structures, in such industries as civil engineering, transportation, energy, aeronautics, and research and development.

Beneficial features of the FiberSensing FS62 Strain Sensor include:

• Long-term reliability, due to its design, materials, and packaging;
• Immunity to EMI, RFI, and other effects, making it safer to use in dangerous work environments;
• High multiplexing capability, as many sensors can connect to a single optical fibre;
• Remote sensing between several kilometres;
• Compatibility with most interrogators, with a calibration sheet for configuration assistance; and
• Self-referenced, based on the Bragg wavelength.

The HBM FS62 Athermal Strain Sensor has a proprietary design that cancels the intrinsic fiber optic thermal sensitivity to ensure athermal operation of the strain gauge. As a result, users do not need to measure temperature to compensate for cross-sensitivity, creating a boon for performance and large-scale system design.

Advantages of the FS62 Athermal Strain Sensor include its intrinsic athermal design, which users can adjust to compensate more for a structure’s thermal expansion; this allows workers to measure the stress and load-induced strain components of the structure. Like the FiberSensing FS62 Strain Sensor, it has a high multiplexing capability, which simplifies network and installation.

HBM has a strict quality-control program that tests sensors for high standards of performance and endurance. The manufacturer checks and individually calibrates each product before shipping it out.
