Accutherm® High Accuracy Thermocouple Wire

Products Specialty Products Accutherm® High Accuracy Thermocouple Wire

Accutherm® Thermocouple Wire 

ACCUTHERM™ was developed to be the answer for when extreme accuracy in temperature measurement is needed. This thermocouple wire surpasses the performance of ASTM/ANSI special limits initial accuracy tolerance. The initial calibration tolerance for ACCUTHERM™ is approximately four times that of standard limits thermocouple wire and double that of special limits thermocouple wire. It is available with any of TE Wire & Cable’s standard insulations. Whether your process is Heat Treating or Autoclave Validation; Performance Testing or Research and Development; Aerospace or Metals, ACCUTHERM™ will give you the temperature accuracy readings you need to remain competitive. When high accuracy temperature measurements are critical to your process, ACCUTHERM™ is the answer.

The accuracy of thermocouple wire is expressed as deviation from the published NIST voltage versus temperature relationship for each type of wire. This chart shows the accuracy advantage of ACCUTHERM™ thermocouple wire over the initial calibration tolerances for standard limits and special limits.

Technical Information

Business and industry are spending considerable time and money improving the efficiency of their manufacturing processes. Reducing scrap, increasing through-put, and improving product quality are today’s benchmarks for success. Temperature is the most frequently measured process variable. To be competitive, industry needs to control and monitor process temperatures to the highest degree of accuracy. In response to this need, TE Wire & Cable has developed ACCUTHERM™, a super accurate thermocouple wire which surpasses the performance of ASTM/ANSI special limits initial accuracy tolerance. The accuracy of thermocouple wire is expressed as deviation from the published NIST voltage versus temperature relationship for each type of wire. This chart shows the accuracy advantage of ACCUTHERM™ thermocouple wire over the initial calibration tolerances for standard limits and special limits.
