[Endian Electric] how to determine the infrared temperature target size

Infrared thermometer based on the principle can be divided into monochrome thermometer and two-color thermometer (radiometer colorimeter). For monochromatic thermometers, when measuring temperature, the measured target area should be full of thermometer field of view. It is recommended that the measured target size exceed 50% of the size of the field of view. If the target size is smaller than the field of view, background radiation energy will enter the thermometer's visual symbol and interfere with the temperature readings, causing errors. Conversely, if the target is larger than the thermometer's field of view, the thermometer will not be affected by the background outside the measurement area. For colorimetric thermometers, the temperature is determined by the ratio of the radiant energy in two separate wavelength bands. Therefore, when the target to be measured is small and does not fill the field of view, there are smoke, dust, and blockage on the measurement path, and when the radiation energy is attenuated, it does not have a significant impact on the measurement results. For small but sporty or shocking targets, colorimetric thermometers are the best choice. This is due to the small diameter of the light and its flexibility to transmit light radiation energy in curved, blocked, and folded channels.

For the infrared era dual-color pyrometer, the temperature is determined by the ratio of the radiant energy in two separate wavelength bands. Therefore, when the target to be measured is small and there is no full scene, smoke and dust on the measurement path and the attenuation of the radiation energy will not affect the measurement result. Even in the case of 95% energy reduction, the required accuracy of temperature measurement can still be guaranteed. Targets that are small and are in motion or in vibration; sometimes moving within the field of view, or may be partially out of the field of view. Under these conditions, using a two-color thermometer is the best choice. If it is impossible to aim directly between the pyrometer and the target, and the measurement channel is bent, narrow, and obstructed, the bicolor optical fiber pyrometer is the best choice. This is due to its small diameter, flexibility, and ability to transmit optical radiation energy over bent, blocked, and folded channels, and therefore can measure targets that are difficult to access, have harsh conditions, or are near an electromagnetic field.

Die Cutting Machine

Die cutting machine is also known as a beer machine and CNC punching machine, it is mainly used for the corresponding non-metallic materials, sticker, EVA, double-sided adhesive, electronics, mobile phones, pads and other die-cut (full cut or kiss cut), the indentation and bronzing job fit, automatic waste discharge, die-cutting machines use blades, metal molds, steel wire (or steel plates carved into the template) to apply some pressure by stamping version, printed materials or cardboard rolled and cut into a certain shape. Cutting machines are very important equipment in the post press packaging molding process.

Die-cutting Machine Working Principle
Working principle of die cutting machine is to use the steel knife, metal molds, steel wire (or steel plate engraving templates), the pressure applied by embossing version, make the printed materials or cardboard rolled and cut into a certain shape. If the pressure of the entire printed materials cut into a single graphics products, this is called die-cutting; if use the two templates of upper and lower by the mold to heat up to a certain temperature, to leave the bending groove marks is called indentation on the surface of the printed products stamping having a three-dimensional effect of the pattern, or font called bronzing; if use a substrate to multiplex on another substrate, this is called bonded; excluded from inter authentic outside the remaining portion of said above collectively referred to as die-cutting technology for waste; the working principle of the automatic die cutting machine is the feeding machine feeder parts sent the paper to the front and the regulatory and side provisions bit, and then the tooth row send the paper to the die secondary positioning for cutting, after die-cutting and then again from teeth row to the platoon served stripping agencies, after stripping and then enter the delivery section, thus completing a die-cutting job.
