Paper Abstract

One of many hazards in industry is presence of airborne dust. Recently, we have proposed a "dust measuring sensor," operating on light scattering effect and constructed in space-optics technique. Tests of the device performed in normal operating conditions in a coal mine underground showed it worked properly and met requirements of that application except of zero-drift stability. The unsolved problem was dirtying of optical elements of the device during work by dust. Operating conditions of such a device are cruel -- humidity, elevated temperature, vibrations, and over-all contact with dust are harmful for optics. Thus, achieving reliable indications of the sensor is really a challenge. In the present work we test the idea to solve this problem by replacing bulk optics in the sensing area by optical fibers. First laboratory examination and operational tests of the fiber-optic sensor are also reported.
