AST Thermocouples, RTDs, Thermistors and Custom Temperature Assemblies

PRODUCTS:

• Thermocouples generally can measure temperatures over wide temperature ranges, inexpensively, and are very rugged, but they are not as accurate or stable as RTD’s and Thermistors.

• RTD’s are stable and have a fairly wide temperature range, but are not as rugged and inexpensive as thermocouples. Since they require the use of electric current to make measurements, RTD’s are subject to inaccuracies from self-heating.
• Thermistors tend to be more accurate than RTD’s or thermocouples, but they have a much more limited temperature range.
