Robust and simple-to-install sensors that can measure strain on steel structures straightaway

Darmstadt, Hesse -- (SBWIRE) -- 06/30/2017 -- HBM FiberSensing has redesigned its compact FS62 optical weldable strain sensor. This compact sensor is designed with a stainless-steel cover sheet which allows it to be spot-welded to steel structures and materials. It is now available in a new version (2.0) suited to be welded with low-power portable welding devices.

The newly launched version of the FS62 optical weldable strain sensor can be spot-welded more easily and without compromising measurements using a larger number of portable welding machines. By reducing the power needed for the welding process, installation becomes less challenging, i.e., requiring no previous sensor welding experience. With a thinner cross section and reduced rigidity, the FS62 sensor is now more flexible, meaning it can now also be applied on slightly curved surfaces and not only to flat ones.

Extra resistance and durability

FS62 optical weldable strain sensors were also redesigned to bear no pre-tension on the Fiber Bragg Gratings (FBG) in order to increase their robustness and fatigue resistance; as the fiber is no longer always under tension, the levels of effort on the fiber are smaller when traction is applied. Their traditional resistance has been kept with the use of armored cables to withstand harsh operating conditions found in field installations.

Moreover, installation without the use of adhesives allows these sensors to endure long-term attachments and ensures an extended service life. The FS62 sensor is recommended for field installation in, for example, pipelines, heavy duty metallic structures (cranes, turbines, generators), wind turbine structures, railways, bridges and all other steel structures that require strain measurements.

Compatible with most optical interrogators

The FS62 sensors are compatible with most common optical interrogators and are suitable for remote sensing, making it possible to install them far away from the data acquisition device.

This sensor, in particular, uses 9 m core fiber and high reflectivity gratings making it suitable for use in cases of very long distances between the interrogator and the sensors network and compatible with standard telecommunication fiber for signal transmission. Compatible with other sensors from the FS line, FS62 optical weldable sensors can also be assembled in array (K-SYS-FSA) using a single optical fiber.

Innovative complete solution for testing electric drives and inverters. Efficiency mapping in minutes rather than days

Darmstadt, Hesse -- (ReleaseWire) -- 06/02/2017 -- HBM Test and Measurement (HBM) complements its "HBM eDrive Testing" enhanced power analyzer with additional functions for testing 6-phase machines. This integrated solution enables torque, electrical quantities, temperatures, CAN bus, and other signals to be measured in an extended range of applications.

"HBM eDrive Testing" is a custom measurement system for testing inverter-fed electrical machines. Unlike conventional power analyzers, "HBM eDrive Testing" provides unique and greatly accelerated data acquisition and analysis options.

"HBM eDrive Testing" ensures efficiency mapping in minutes rather than days, and thus goes far beyond conventional solutions that use power meters and subsequent PC analysis. The modular measurement system can be upgraded from 3 to up to 51 power channels per mainframe at any time. It is ideal for 3-phase applications and, with the latest enhancement, also for applications with multiple channels such as 6-phase machines, hybrid or multiple-motor drives.

In addition to its power analyzer fun HBM eDrive Testing enhanced power analyzer actions, "HBM eDrive Testing" provides all the features of a cutting-edge data acquisition system (DAQ). It allows the synchronous acquisition of electrical signals as well as torque, rotational speed, temperature, CAN bus, vibration, and many other measured quantities. All data is stored in real time, either continuously or driven by set points.

The T40B and T12HP torque transducers (for the highest standards of precision) ensure precise acquisition of mechanical quantities. High-voltage probes with up to 7.2 kV rms enable medium-voltage motors to be directly connected to the measurement system, without affecting the precision of data acquisition or the safety of the user. Unique, isolated digitizers are available for use with motors in the high-voltage range, exceeding 10 kV.

HBM introduces a data recorder and data acquisition (DAQ) software that provides extensive structural health monitoring functions

Darmstadt, Germany -- (ReleaseWire) -- 05/15/2017 -- HBM Test and Measurement (HBM) provides the QuantumX data acquisition system and catman data acquisition software as a comprehensive structural health monitoring package for data acquisition on bridges, tunnels, wind turbines, and other buildings and infrastructures. The package features a function that allows a single data recorder to be used for taking different measurements in parallel, thus adding extra flexibility.

Up to 15 different measurement tasks per data recorder can be performed in parallel and saved fully autonomously at a total sample rate of up to 5 MS/s. The catman software enables the number of channels and sample rates to be individually set for each measurement, and allows the start and end conditions to be separately controlled. Therefore, it is easy to implement complex tasks such as the monitoring of multiple tracks or lanes on a bridge. Furthermore, users have higher flexibility in acquiring data in a more targeted and efficient way.

Integrated FTP server ensures convenient data transfer

In addition, catman generates a separate file for each measurement task, which can be stored locally and automatically uploaded to an FTP server. The software provides a wide range of functions for subsequent analysis such as signal computation, frequency analysis, and intelligent data reduction.

The HBM Push app ensures that you never miss an important event again

The HBM Push app is an integral part of the structural health monitoring package. It notifies the user about specific events occurring on the monitored object – by sending a push message to the user's smart phone, no matter where they are. The catman software allows the user to define these events. The Push ID can also be shared to notify others about the events. Security is guaranteed: All messages are encrypted during transmission. This app is available for free.

This and other catman 5.0 functions are well-suited for structural health monitoring as well as for mobile road tests and long-term measurements in test benches and for durability analysis and development tests.
