Conventional use of thermocouple temperature measurement is limited by use environment (high temperature, high pressure) and structure, temperature fluctuation is big, vibration and installation
It under the influence of the factors such as mode, causes that the thermocouple service life is short, accuracy of measurement is unstable, troublesome maintenance, is encountered when really
When thermocouple break, it is also possible to which in addition the awkward that can not be replaced is to be made using the shortcomings that product facilities such as infrared temperature-measuring gun
Cause measuring result error big with the influence of environment and distance, can not continuous real time temperature measurement, or even need to arrange special survey
Amount personnel's inspection trips, while also needing to record in measurement, it has both increased cost and has also wasted manpower.
The country is in the temperature monitoring system of hot-blast stove at present, and there are mainly two types of for the temperature sensor being commonly used:
1, platinum rhodium thermocouple, 2, non-contact type photoelectricity or radiant type infrared temperature probe, the application to both the above sensor, make with
Lower simple analysis: 1, platinum rhodium thermocouple thermometric is limited by use environment (high temperature, high pressure) and structure, temperature fluctuation is big, vibration
Under the influence of the factors such as dynamic and mounting means, cause that the thermocouple service life is short, accuracy of measurement is unstable, troublesome maintenance.2,
Non-contact type photoelectricity or radiant type infrared temperature probe are influenced to cause measuring result error big by use environment and distance, no
The continuous real time temperature measurement of energy, or even need to arrange special survey crew's inspection trips.
