Primary Sensors for Glass Industry

At the end of the course, students should be able to: 1. identify different primary sensors in glass industry; and 2. explain primary sensors as temperature and radiation sensitive devices used in measuring the furnace atmosphere during heat treatment of glass.

Temperature measuring devices; thermocouple, recitation pyrometers, total radiation, spectrally selective optical and two-colour pyrometers. Thermometers; gas liquid and resistance thermometers. Thermistors, pyro metric cones. Flow measurements; orifice plate, flow nozzle, venture tube, laminar flow element, pilot tube. Variable area, Turbine and magnetic flow meters pressure transmitters and strain gauges.
