Optical sensor pyrometer for portable non contact high temperature measurement by comparing a brightness reference lamp at 0.655 microns. Optical Datasheet (90 KB)

Classification - Optical sensor, non contact high temperature measurement, radiation pyrometer.

The PYRO Optical pyrometer temperature sensor for non contact high temperature measurement operates by allowing the operator to compare the intensity of light radiated from a target at visible .655µm wavelength to the known brightness of an internal calibrated lamp. This is achieved by utilizing a rotating optical photoscreenic wedge that functions as a variable neutral density filter. The PYRO Optical pyrometer can achieve temperature measurement accuracy to ± 0.5% of the temperature being observed. Small target sizes from 0.055" at distances of 3" to infinity can be achieved. Supplementary magnification lenses for smaller targets at shorter distances are available. The "PYRO" Optical pyrometer features a circular direct reading scale on the instrument. Several models provide temperature scales in °F, °C or both. The PYRO Optical pyrometer units are constructed in a rugged steel housing providing years of trouble free industrial plant use. The PYRO Optical is a portable unit and comes complete with rechargeable NI CAD battery and carrying case.

The PYRO Optical radiation pyrometer is used for many industrial applications to measure non contact high temperature measurements.  The optical sensor red scales can be provided for emissivity correction of targets with a 0.4 emissivity value.  This is useful for temperature measurement of molten iron & steel.  The PYRO Optical pyrometer is calibrated at an effective wavelength of 0.655µm and is inherently less subject to most errors due to uncertain emissivity or extraneous reflected light   than infrared or radiation thermometers.

The PYRO Optical pyrometer is easy to use.  The operator rotates the knurled photoscreenic wedge ring on the housing of the optical pyrometer while viewing the target.  A color blend is made between the internal calibrated lamp through the instruments photoscreenic wedge and the target.  The temperature measurement is indicated on a direct reading scale on the housing of the instrument.  The light viewed by the operator is monochromatic. Therefore, readings are not effected by an individuals color sensitivity.
