Request InfoHBM Inc.MARLBOROUGH, Mass., Aug. 12, 2013 — HBM Inc.’s T40B and T40FM torque transducers include an integrated speed measurement system for work in harsh environments, such as those containing humidity, condensation, dust, oil and grease. The devices take measurements based on the contactless sensing of an anisotropic magnetoresistive sensor, making the transducer signal more robust and stable than that of an optical system. Able to measure torque and speed (with a 1024-pulse output) simultaneously, the devices also offer a higher resolution than traditional optical systems.

A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookSpectroscopy: The Tools of the Trade: Understanding the whys and wherefores of a technology goes a long way toward solving your problem.
