Information

Hidden wire optical pyrometer
The working current of the high temperature bulb is changed by adjusting the resistance. When the brightness of the filament is consistent with the brightness of the object to be measured, the brightness of the bulb represents the brightness temperature of the object to be measured.

dual wavelength pyrometer manufacturers

The optical system of the hidden wire optical pyrometer is a red filter, resulting in a narrow effective wavelength absorption glass, the purpose is to expand the range; the eyepiece and the objective lens are a set of optical systems; the electrical measurement system includes indicating instruments, bulbs, power supply and adjustment. Resistor in four parts.
Constant Brightness Optical Pyrometer
Use the dimming wedge to change the brightness of the object to be measured, so that it is compared with a high-temperature bulb with a constant brightness temperature. When the brightness of the two is equal, the brightness temperature of the object to be measured is determined according to the rotation angle of the dimming wedge. Because the structure and use method of the hidden wire optical pyrometer are better than the constant brightness type, it is widely used.
Photoelectric Pyrometer
Photoelectric pyrometer is a new type of temperature measuring instrument developed on the basis of optical pyrometer measurement theory. It adopts a new type of optoelectronic device to automatically balance to achieve the purpose of continuous measurement.
radiation thermometer
It is measured according to the total radiation intensity theorem, that is, the total radiation intensity of an object is proportional to the fourth power of the temperature of the object. It can be used to measure the high temperature of 400-20000 ℃, and most of them are on-site installation structures.
