| 摘要 |
The invention relates to an apparatus for calibration and characterisation of instruments for measuring temperature by telemetry, comprising a casing, a black body cavity comprising a front opening as a low temperature (-20°C to 40°C) uniform thermal radiation source, a reference thermometer and a verification thermometer, a coolant recirculation system, a vertical arrangement of thermal gradient plates for generating temperature gradients of between -20°C and 80°C, each plate comprising a T-type thermocouple, a heating element and a cold lower plate (with temperatures of between -20°C and 80°C), two temperature controllers for setting the working temperature of the coolant fluid and for controlling the temperature of the hot upper plate, a system for collecting data for the data register which is connected to a PC in order to view data, a controller of the system and a general power controller. |
