Fullerton, Calif. TT electronics BI Technologies Electronic Components Division offers a cold junction compensation (CJC) module that is designed to enhance the accuracy of thermocouple temperature measurement in power electronic applications. Designated Model 143-131A, the CJC module features a hybrid SIP configuration to save board space.
The CJC module is said to achieve accurate compensation by using laser-trimming and an environmentally stable, robust construction that includes a ceramic base and hybrid technology. It is available in a standard three-terminal package and uses an active semiconductor that enhances the accuracy of temperature measurements when used with standard thermocouples. The module is compatible with most data acquisition manufacturers' mounting boards and terminal blocks.
The 143-131A CJC module features an output voltage slope of -2.5 mV/°C and an accuracy of ±1.25°C within the operating temperature range of -40°C to 85°C. Custom specifications are available.
Pricing: Typical pricing is approximately $3.00 each in volume.
Availability: Delivery is from stock to eight weeks.
