Metrology

The model 5848 MicroTester is designed for testing MEMs, photonic, and microelectronic devices.

A noncontacting angular position sensor from BEI Duncan Electronics in Tustin, Calif., combines transceiver technology with digital-signal processing to detect the angular position or movement of a shaft.

Measuring torque in real time has stymied engineers for years. Strain gages provide a partial solution, but they are too delicate for hostile environments.

Timing-belt tensioning and planetary gearheads that maintain out-of-box backlash levels for life are just some of the topics covered in this mechanical reference guide.

The TSE mechanical encoder from CUI Stack Inc., Beaverton, Oreg., features a hollow shaft, eliminating the need to place the encoder directly behind the front panel.

The days of testing a design by traditional trial- and-error methods are gone.
