What is IR pyrometer?
IR Pyrometer is an electronic device that is able to measure the temperature from a distance. They act using infrared light and are able to detect thermal energy without being in direct contact with the object. These devices are also known as "infrared thermometers" or "end thermometers" and are commonly used in industrial, medical and safety applications.
The name "pyrometer" comes from Greek words for "fire" and "measurement". The IR pyrometer consists of both the electronic detector and the lens. The lens is used to focus the thermal radiation of the object on the electronic sensor. This sensor converts infrared energy from hot surface to an electronic signal. The higher the signal, the warmer the object. Most infrared pyrometers use a digital display to present the temperature value in Fahrenheite or Celsius.
Not all objects and environments have the same thermal properties. This means that IR pyrometer is not always perfect. If the superficial is absorbedIt, most of its thermal radiation does not reach the detector and fake read. The dense atmosphere caused by the accumulation of fog or gas can also cause incorrect thermal reading. Infrared pyrometers are the most accurate in measuring solid flat surfaces such as walls.
pyrometers may have different fields of view depending on the type of lens. Some lenses are designed to focus thermal radiation from a small area, while others are designed to view a wide area of heat. Ideally, the target object should fill the entire pyrometer field. If this is not properly focused, the background radiation can affect the sensor reading. Most devices should be used from a certain distance or allow the operator to change lenses for different ranges.
Many pyrometers use a visible laser that is built into the unit. A device with this function is sometimes called "laser thermometers." LaserovThe beam is intended to help with the correct focus of the pyrometer, but it is not an essential part of the actual temperature measurement process. Some IR pyrometers use a series of lasers to project a circle on the target object. This projection is used to illustrate the range of thermal lens tracking and help users correctly to place the device.
These devices can be very useful in applications where traditional thermometers are not ideal. For example, high -level electrical transformers can be a dangerous touch. IR pyrometer allows technicians to measure the surface temperature from a safe distance. Pyrometers can also be used to measure temperatures that move or too far to achieve normal tools.
