1 Description
Endurance series pyrometers are infrared noncontact temperature measurement systems. Such devices have an
adjustable focus, a through-the-lens sighting capability, and a parallax-free optical axis. They are energy
transducers, designed to measure accurately and repeatedly the amount of heat energy emitted from an object,
and then convert that energy into a measurable electrical signal. Each model operates as an integrated
temperature measurement subsystem consisting of optical elements, spectral filters, detectors, digital electronics
in a sealed housing. Each is built to operate on a 100 percent duty cycle in industrial environments. Various output
types are offered for easy integration into industrial monitoring and control environments.
Monochrome models (1-color) for standard temperature measurement applications
The 1-color mode is best for measuring the temperature of targets in areas where no sighting obstructions, either
solid or gaseous, exist. Such 1-color mode is also best where the target completely fills the measurement spot.
Ratio models (2-color) for specific temperature measurement applications
Ratio pyrometers determine the object temperature by the ratio of two separate and overlapping infrared bands.
The 2-color mode is best for measuring the temperature of targets that are partially obscured, either intermittently
or permanently by other objects, openings, screens, or viewing windows that reduce energy, and by dirt, smoke,
or steam in the atmosphere. The 2-color mode can also be used on targets that do not completely fill the
measurement spot, provided the background is much cooler than the target. Ratio pyrometers can measure and
determine the object temperature in either one of both modes (1-color / 2-color), in which always 2 infrared
detectors are active.
