Fiso Technologies Inc. has introduced the FTI-10 battery-powered interferometric sensor. The 1/8 DIN white-light device is fully compatible with the company's Fabry-Perot-based fiber optic gauges including fiber optic strain, temperature, pressure and displacement gauges. Employing an ultrastable dielectric thin film Fizeau interferometer, the FTI-10 provides precise and absolute measurements in difficult-to-reach locations and hostile environments. Features include 0.01% full-scale resolution, 0.1% accuracy, 10-Hz standard sampling rate, 15,000:1 dynamic range and a 1 3 16-character LCD. The sensor can be used for spot checks and online monitoring in aerospace, food processing, industrial process control and other applications. An RS-232 output is available.
