Module Delivers Accurate Temperature Measurements

The 143-131A, a cold junction compensation module, employs a PN junction that enables accurate temperature measurements when paired with standard thermocouples. Reportedly, the module features laser-trimmed accuracy as well as an environmentally stable construction that includes a ceramic base and hybrid technology to ensure thermal equilibrium. Features include an output voltage slope of -2.5 mV/°C and an accuracy of ±1.25°C within an operating temperature range from -40°C to +85°C. Custom modules with specifications outside of these parameters are available upon request. Typical pricing for the 143-131A CJC is approximately $3 each in volume with lead times from stock to eight weeks. BI TECHNOLOGIES, Fullerton, CA. (714) 447-2518.
