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

The PYRO MicroTherm optical pyrometer temperature sensor for non contact high temperature measurement is a disappearing filament pyrometer for precision high temperature measurements on small targets to 0.0005". One of the many benefits associated with the PYRO MicroTherm is that the target need not fill the entire field of view. This is especially effective when measuring targets such as wire. The PYRO MicroTherm's telescope uses a proven high quality huygen microscope type ocular which provides 20x magnification of the target area.  The in view instrument filament allows precision intensity matching capability to 2-3°C repeatability. The PYRO MicroTherm's digital display electronic unit allow users to insert an emissivity value to display an emissivity-corrected temperature. For on-line data transmission applications, the PYRO MicroTherm optical pyrometer provides both analog and digital outputs.

The PYRO MicroTherm radiation pyrometer is ideal for many small target laboratory and industrial applications.  It is extremely useful when measuring small targets that do not fill the entire field of view.

  • Crystal Growth
  • Calibration Standard

 

The MicroTherm non contact temperature measurement is determined by adjusting a precision rheostat on the PYRO MicroTherm's housing that changes the internal calibrated lamp’s intensity.   Using the inherent ability of the human eye the operator the unknown intensity of light radiated from a hot target at 0.655 µm until a color blend is made between the apex of the pyrometer's calibrated lamp and the target. The current value to the lamp then is output via analog or digital signal to a temperature display.   Temperature ranges can be measured between approximately 1300 to 5800°F (700 to 3200°C), but with appropriate filters and Micro-Optical analog meter, the MicroTherm's temperature ranges can be extended to approximately 18000°F (10000°C). The optional Enhanced Imaging Optics enable crisp crystal clear images which is extremely useful when viewing multiple miniature items of different temperature concurrently.
 
Color Blend For Temperature Indication

The schematic drawing right illustrates a PYRO Micro-Therm target as viewed through the instruments telescope. The instruments telescope provides a clear, enlarged 20x view of the target. A color blend is made between the apex of the instruments lamp and the target.
