Infra-Red Thermometer

Raytek Corpn introduces the Thermalert GP Series which enables infra-red temperature measurement to compete with thermocouples and other probe devices. The cost factor is especially significant in a wide range of multiple-sensor web applications. Examples are paper, textile and plastic production, where non-contact methods allow measurement of the actual process material rather than the heating medium. The series features a -18 to 538?C temperature range, compact or miniature sensing head, and a one eighth (1/8) DIN digital monitor with comprehensive signal conditioning. The specification equips the Thermalert GP for a variety of applications. These include continuous ovens and web processes in the food, paper, textiles and plastics industries, where monitoring or controlling temperature profiles across a surface is vital, and direct contact sensing is impractical. Measurements in printing, packaging material manufacture, pharmaceuticals, automotive paint drying and predictive machinery maintenance can also benefit from this approach. Application flexibility is accomplished through a selection of sensor optics, sizes, and accessories. Integral signal conditioning provides peak/valley hold, averaging, and fixed background ambient temperature compensation, along with an adjustment to correct for different target material characteristics. The instrument has a user configured, 4-20 mA signal output, and dual set-point alarm or control contacts. It is powered from 110/220 V AC, 50-60 Hz line voltage, eliminating special power supplies. Accessories include cooling and purging attachments for extreme environments and a right angle mirror for applications where direct line-of sight is not possible.
