Sensor Safely Monitors Fluid Levels

Facebook X LinkedIn Email
A liquid-level sensor developed by Jonathan D. Weiss at Sandia National Laboratories in Albuquerque, N.M., eliminates the hazards of monitoring fluids in explosive environments such as fuel tanks. The sensor, which is an outgrowth of his fiber optic shock-wave position sensor, eliminates the need for electrical and optoelectronic conversion components in or near the tank. Weiss doped a methyl styrene slab with an organic dye that absorbs blue light and fluoresces in the green. In tests that he reported in the August 2000 issue of Optical Engineering, the researcher used 476-, 488- and...Read full article
