Oh great!!! You do calibrations, what once a year? And NOW yer in a BIG �time is critical� rush. �Speed in reply is appreciated.� And why couldn�t you have asked this question 6 months ago? Just what have you been doing since the last calibration?
A thermocouple is made by welding two wires of different metals together. Thermocouple Type||Materials B||Platinum30% Rhodium (+) Platinum 6% Rhodium (-) C||W5Re Tungsten 5% Rhenium (+) W26Re Tungsten 26% Rhenium (-) E||Chromel (+) Constantan (-) J||Iron (+) Constantan (-) K||Chromel (+) Alumel (-) N||Nicrosil (+) Nisil (-) R||Platinum 13% Rhodium (+) Platinum (-) S||Platinum 10% Rhodium (+) Platinum (-) T||Copper (+) Constantan (-)
When you purchase a thermocouple, you must tell the sales-type the following: * Thermocouple type [ie, J, K, E, T, etc]. * Wire size range, may be 0.0100 to 0.1285 inch * Sheath material [ie, Inconel, stainless steel, PTFE, etc]. * Sheath diameter [ie, 1/16 inch, 1/8 inch, 3/16 inch, 1/4 inch, etc]. * Thermocouple junction [ie, exposed, grounded, ungrounded, etc]. * Sheath length [ie, 12 inch, 24 inch, etc]. * Connector type [ie, BNC, SMB, banana jack, thermocouple plug, 9-pin D-Sub connector, none, etc].
The measuring temperature is limited only by thermocouple type and sheath material. * Type K is appropriate for a temperature range of 32 to 2,300�F (0 to 1,259.99�C). Look here http://www.conaxbuffalo.com/tech/emf/TypeKF.pdf
