Thermal temperature cameras are suitable for non-contact temperature measurement projects in all companies worldwide. Spot thermometers are another widely used non-contact temperature measurement tool for industrial applications. They work on the same principle as thermal temperature cameras: detecting infrared radiation and then converting it into temperature readings.
(1) The point thermometer only displays numbers, while the infrared camera can generate images.
(2) The point thermometer can only read the temperature of a single point and the thermal temperature camera displays the temperature readings of all the pixel points in the thermal image.
Being equipped with advanced optics, thermal temperature cameras can detect temperatures at greater distances, which helps to examine large areas.
Spot pyrometers are also commonly referred to as infrared thermometers. Since it works on the same principle as an infrared thermometer, it can be considered as an infrared thermometer with only one pixel point. This tool can perform multiple tasks. But because it can only measure the temperature of a single point, the operator misses a lot of critical information and is unable to notice certain high temperature critical components that are about to fail and are in urgent need of repair.
Similar to spot thermometers, thermal temperature cameras also provide non-contact temperature readings. The difference is that a thermal temperature camera can display thousands of temperature readings at the same time, with each pixel corresponding to a temperature reading.
(1) Thermal temperature cameras can save time and detect heat
A thermal temperature camera not only measures the temperature of thousands of points, but also converts the temperature readings into a thermal image. The generated thermal image can fully reflect the overall condition of the equipment to be inspected, and the operator can immediately discover subtle hotspots that are not easily detected by the spot thermometer.
In addition, thermal imaging saves a lot of time, as it is time-consuming and labor-intensive to use a spot thermometer to measure large areas with a large number of components installed, as each part needs to be scanned individually. Thermal temperature cameras can be used to check printed circuit boards for heat dissipation, to complete quality inspections or to check for thermal effects in the automotive industry, or for failure analysis in the laboratory.
In order to accurately measure the temperature of an object using a spot pyrometer, the target object needs to be completely covered with spots of light. This limits the distance at which accurate temperature measurements can be taken. Another advantage of thermal temperature cameras over spot thermometers is the ability to accurately measure the temperature of an object at a greater distance. The ability to measure the distance to a target of a given size is called the "distance factor ratio" (D:S) or "spots ratio" (SSR).
