Intrinsically safe infrared (IR) thermometers are the latest source of portable temperature measurement devices available to operators of hazardous plants requiring IS equipment. Raytek have available a full range of IS and Ex units for fixed or portable applications.
Designed for accurate temperature investigation in all types of environments, Raytek’s IS models include portable units with temperature ranges from –32 to 900°C and fixed units with simple 2 wire loops and programmable ranges up to 2000°C. Certification includes PTB Approval EXII2GG EExibIICT4, Atex 100a on fixed units and Fm Approval, US Standard for portables.
The popularity of infrared thermometers continues to grow because of their ease of use, reliability and affordability. Like traditional thermometers, IR devices translate hot and cold into numeric measurements. However, unlike traditional methods, an IR thermometer does not require contact with the object under measurement, simply point and read the temperature in the display.
High temperature thermocouple replacement has become an increasing requirement due to the rising cost of materials, non-contact IR units are proving to be a long lasting viable alternative for many sites.
Instantaneous reading and reliable results make trouble shooting quick and easy and with less chance for error. IR thermometers help process and maintenance engineers to check the plant quickly, giving them the information needed to assess and plan any maintenance requirements. In addition some portable IR thermometers are available with logging features so temperatures can be stored and retrieved later, this is ideal for record keeping or report backs.
