OPERATIVE TEMPERATURE SENSING SYSTEM

摘要

The system uses an ambient temperature sensor and a globe-type temperature sensor. The second temperature sensor is located in the chamber and generates a signal that is a function of the temperature within the chamber. The signal modifying circuits comprising amplifiers with feed back resistors receive the output signals from the two sensors and change the signals by two fixed and predetermined amounts. An amplifier summing circuit receives the two sensor signals and produces a output which is a function of the temp. within the enclosed space. The system may also use a reference signal representative of a desired set point temp.
