Measuring principle and characteristics of 2color pyrometer
The 2 color pyrometer has high sensitivity and fast response, can observe small targets, and has high halo measurement accuracy.
Precautions and areas for the use of two-color pyrometers
Two-color pyrometer series, the device works in two spectral ranges at the same time and determines the temperature by calculating the radiance ratio.
Advantages of two-color pyrometers
That is to measure the infrared radiation brightness emitted by an object in two different spectral ranges and infer the temperature of the object from the ratio of the two radiation brightness, which is called a two-color thermometer.
Use a two-color thermometer to determine target size
Two-color thermometers can be divided into monochromatic and two-color thermometers (radiation colorimetric thermometers) according to the principle.
Features and Precautions of Two-color Pyrometer
The two-color pyrometer enables very fast data acquisition: standard version with response time of less than 1ms, high-speed design provides measurement results, depending on the model with 40 or 80µs output.
How a two-color thermometer works
At two selected infrared wavelengths and a certain bandwidth, the ratio of their radiant energy varies with temperature. Has the following performance characteristics:
How to use the two-color thermometer correctly
Two-color thermometers can be divided into monochromatic and two-color thermometers (radiation colorimetric thermometers) according to the principle.
Checks before starting the two-color pyrometer
In order to ensure the normal operation of the instrument is not affected by the environment, check the environment before starting the machine.
What are the advantages of a two-color pyrometer over a single-color pyrometer
In temperature measurement, the two-color pyrometer does not change with the surface state of the object (different surface roughness, or the chemical state of the surface is different),
