Product Description
The Endurance 1R Series of instruments are 2-color infrared noncontact temperature measurement
systems with variable focus, through-the-lens sighting, and parallax-free optics. 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. Temperature measurements
can be taken using either of the following modes:
•
1-color mode
– for standard temperature measurements. The 1-color mode is best for
measuring the temperature of targets in areas where no sighting obstructions, either solid or
gaseous, exist. The 1-color mode is also best where the target completely fills the measurement
spot.
•
2-color mode
– temperatures are determined from 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.
Each model operates as an integrated temperature measurement subsystem consisting of optical
elements, spectral filters, detector, digital electronics and an IP65 (NEMA-4) rated 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.
