Abstract
The invention relates to a device for correcting error in temperature readings caused by thermocouple-to-extension wire ambient temperature fluctuations. The device creates an isothermal mass which raises the temperature of terminals to higher than ambient temperature. The isothermal mass consists of a self heating thermistor surrounded by thermal conductive epoxy inside an isothermal mass which contains the terminals. The isothermal mass is enclosed within insulating discs using a closure casing to complete the assembly. Using these higher than ambient temperature terminals for the connection between a thermocouple and extension wires, any error due to ambient temperature fluctuations is minimized.
