What sensor is better for industrial infrared thermometer to measure temperature?
1. Non contact measurement: It does not require contact with the interior or surface of the measured temperature field, so it will not interfere with the state of the measured temperature field, and the thermometer itself is not damaged by the temperature field.
2. Wide measurement range: Due to its non-contact temperature measurement, the thermometer is not located in a high or low temperature field, but works under normal temperature or conditions allowed by the thermometer. In general, it can measure negative tens of degrees to over 3000 degrees, and can also measure moving or vibrating objects.
3. Fast temperature measurement speed: i.e. fast response time. As long as the infrared radiation of the target is received, the temperature can be set in a short period of time, with a fast measurement speed of multiple values per second.
4. High accuracy: Infrared temperature measurement does not damage the temperature distribution of the object itself like contact temperature measurement, so the measurement accuracy is high.
5. High sensitivity: As long as there is a small change in the temperature of an object, the radiation energy will change significantly, making it easy to measure. It can perform temperature measurement and temperature distribution measurement of small temperature fields, as well as temperature measurement of moving or rotating objects. Safe to use and long service life.
6. Has no physical or chemical impact on the tested substance.
7. Measure in explosive, corrosive, high-pressure, or high-temperature environments.
8. Long service life and low maintenance cost.
A key factor in precise industrial measurement is selecting a suitable filter in front of the infrared thermopile sensor. To reduce the dependence of different atmospheric transmittance between sensors and targets, a high-quality filter for the 8-14 µ m range should usually be included. This wavelength range is also known as the far infrared atmospheric window, where almost no absorption occurs. Therefore, the radiation emitted by the object of interest will be almost unchanged and received by the sensor, unaffected by environmental conditions such as temperature or humidity.
The Heimann F8-14 standard filter has sharp edges at 8 and 14 µ m, providing an ideal filter for precise and high-quality industrial measurements with low distance dependence.
Other applications of industrial process control include welding and welding rework, friction welding, exhaust temperature monitoring, and temperature observation using permanently installed or handheld pyrometers.
