How to choose a single color infrared temperature sensor

Infrared temperature sensor , a temperature sensor , and control of the temperature- monitoring device production process or the critical power . Infrared temperature sensor according to the principles can be divided into monochromatic color YLE Engine Coolant Temp Sensor and the temperature sensor . This difference between the two and the selection determines the different performance characteristics .For monochrome temperature sensor during temperature measurement, the measured target area should be full field of view sensor. Recommended target size measured more than 50% the size of the field of view as well. If the target size is smaller than the field of view , the background radiation energy as the sound operator will enter the branch interference temperature sensor readings , causing YLE Crankshaft Positioning Sensor. Conversely , if the target is larger than the field of view thermometer , thermometer would not be out of context affect the measurement area .The ratio of the color temperature sensor is composed of two separate wavelength band of the radiation energy is determined . Therefore, when the measured object are small, full field , measuring the presence of smoke passage , dust barrier attenuation of radiation energy , the measurement results will not be affected , even in some attenuation of 95 % of the cases , still ensure temperature measurement accuracy requirements.For a small target , and is among the target motion or vibration ; sometimes within the field of exercise, or the target portion may be moved out of the field , in this condition , the temperature sensor using the color choice . If this is not under the direct aim and objectives between the thermometer , measuring channel bend , narrow , blocked , etc., two-color fiber optic temperature sensor is the best choice . This is due to its small diameter , flexible , can be bent, folded channel blocking and transmission optical radiation energy , and therefore is difficult to be measured close to the electromagnetic field near the target or harsh conditions .In determining the attachment , should be as standardized services required to reduce installation costs. Survey smoke , dust or other particles to reduce energy signal measurements , color temperature sensor is the best choice . In noise , electromagnetic , vibration, or near ambient conditions is difficult , or other adverse conditions , the optical fiber temperature sensor is the best color .
