Real Time Temperature Measurement for Blast Furnace

May 25, 2006 2 Replies

Hey, What would be the Ideal solution for a Dip Thermometer (by Dip I would meant a probe that would be in constant contact with what ever I wanna measure the temperature of in a furnace) as a permanent installation so I can get REAL TIME temperature.



Hmm... this would be for a lead furnace... so I guess 1000 Degrees celcius would be the temperature of operation atleast... :)



And as for accuracy well say 50 degreees offset wouldnt do any harm I presume...



Another solution I could think of was to drill a hole in the furnace wall and get the probe to be close to the furnace insides. I know there would be a certain offset... but what the hell :)



If theres anyother solution let me know. Cause something tells me the DIP would mean that Id be losing the probe even after a sheeth in about a few months.



I know of the hazards of lead, and all trhe legal requirements and stuff and am looking into them as well...



Just wondering what else can I do as a solution for temperature measurement in Real Time???



Thanks in advance,



Regards Taji



Any possibility to measure with infrared?

Check out using graphite rod as resistor (non-linear) of covering for thermocouple.
