Is there a table that lists the ANSI standards these thermocouple wires are manufactured to?

Asked by: John12345

Whats the maximum sampling rate for this particular thermocouple?

Asked by: Emorenor
Thermocouple wire has no sampling rate. Thermocouples themselves have a certain response time (and that value depends on the model number of the thermocouple) but neither sample rate nor response time are applicable to wire such as this. Thank you.

How can i demonstrate the compliance to the thermocouple composition requirements defined in AMS 2750 ? Can you supply a kind of certificate for this point ?

Asked by: Math83
Thank you for your inquiry. Unfortunately we do not have AMS 2750F Certificates for thermocouple.

Is there T-type TC can be used up to 370 degree Celsius? ( There are values showed in upper temperature limit of protected bare wire TC vs wire diameter in reference guide, but I don't find the corresponding product.)

Asked by: Tabull
Type T Thermocouples can achieve a 370C temperature measurement using bare 14 or 8 AWG wire.

If I weld TT-T-36-SLE to form a TC and calibrate it with a temperature sensor with 0.05C uncertainty, can this TC reach 0.1C uncertainty? Or the TC formed from TT-T-36-SLE also only guarantees the uncertainty showed in omega.co.uk/techref/colorcodes.html?

Asked by: Tabull
Thank you for your inquiry. Thermocouples formed from SLE Wire conforms to calibrations performed at Omega are NIST Traceable and in compliance with Z540-1-1994, ISO 9001 and ISO 10012-1.

What is the errors due to the accuracy of the thermocouple type T? I need this for account for uncertainties.

Asked by: Max J
Thank you for your inquiry! The Standard Limits of Error for Type T is 1C or 0.75% of the reading from 0 to 350C. From -200 to 0C the error will be 1C or 1.5% of the reading. Here is a useful technical reference with a PDF that has this information: https://www.omega.co.uk/techref/colorcodes.html

What is the physical explanation for the existence of upper temperature limit, which is well below the metal melting point and continuous temperature of the insulated material, of double insulated TC wire?

Asked by: Tabull
Hi Tabull, Thank you for the inquiry. The temperature limits are derived from the continuous service limits of the protected bare wire tables. Please refer to details in following link; https://www.omega.com/en-us/resources/thermocouples-sheath-material-and-temperature-limits Best regards OMEGA

Website indicates TT-T-20 is only rated for use down to 32 degrees F. Can I use it down to -320 degreesF?

Asked by: Bobxx C
Thanks for your inquiry. Our wire will go well below zero—most types down to the cryogenic range (~196 deg C or -320 deg F); however, the ASTM-E-230 tolerance specification which Omega's wire conforms to specifically states that wire is normally selected to meet tolerances ABOVE 0 deg C. So while we do guarantee the specs for 0 deg C and above, you may very well find that below zero the wire will still be in specs, but we cannot and are not required to guarantee that. If customers need special accuracy down at the low end, we do offer calibration at customer-specified sub-zero points. This will provide the actual deviation at specific points of concern.
