Title:
CALIBRATED THERMOSTATIC DEVICE FOR THERMOCOUPLE THERMOMETER
Document Type and Number:
Japanese Patent JP2001116630
Kind Code:
A
Abstract:
To provide a calibrated thermostatic device for a thermocouple thermometer eliminating a calibration step after manufacturing an appliance.
In this thermostatic device, a small thermostatic block is assembled on a special printed circuit board including a thick metal plate for imparting sufficient heat capacity and excellent heat conductivity. A temperature sensor is mounted in thermocouple reference junction points on the printed circuit board to observe a temperature in the reference junction points. The thermostatic device also includes a current source for the temperature sensor and a memory device storing calibration data peculiar to the temperature sensor.
