What are different types of IR thermometers?

Infrared (IR) thermometers can be categorized by technologies by temperature measurement they use or some other structural elements. There are three main sensing methods that can use IR thermometers, each depending on different wavelengths of light. Brightness sensors use one wavelength, the ratio sensors use two and more versions of the version are able to use two or more. These technologies can be used in various types of IR thermometers, such as types of hand weapons, highly portable versions of sticks and infrared thermocoups. Similar temperature monitoring technologies can also be found in certain infrared scanning systems and thermal imaging cameras.

There are a number of different ways to measure infrared radiation to determine the temperature of the object. IR thermometers function by measuring the black body radiation, which is distributed as an infrared light. The simplest type of IR thermometer is known as a brightness sensor because these devices use only the only VLNew length for temperature determination. The IR thermometer equipped with a brightness sensor works by measuring the amplitude of the infrared energy emitted by a specific object within this single wavelength. Since only one wavelength is used, these devices may have difficulty returning accurate values ​​if there is any type of interference.

The

ratio sensors use IR thermometers that are able to measure two different wavelengths. These IR thermometers are sometimes called two color sensors because two wavelengths are measured within the infrared range. The use of two wavelengths can allow these thermometers to obtain accurate values ​​through obstacles such as dust or smoke that would adversely affect a single color brightness sensor. Reading the temperature of the two colored sensor can be distorted towards the high side, although there was a significant interference from the Hot source.

Multi-Variant Sensors MoHou observe several wavelengths and are usually modified for use in a specific application. In this case, the emissivity of the object is usually known before the measurement and the sensor is modified accordingly. This can allow multi-variant IR thermometer to provide high-precision readings.

Each of the different IR sensing technologies can be used in a number of devices. One of the common IR thermometer variety is the hand type. These IR thermometers often bear superficial similarity to weapons, including handle, trigger and often laser view. Some types of pocket computers also include built -in tripods to be set on site.

There are also a smaller type IR type. These devices are similar to other manual types, although they are often small or compact enough to be easily transmitted in your pocket. Another type of IR thermometer is an infrared thermocouple, a small device capable of producing the same type of output as a normal thermocouple sensor.
