Abstract

The thermostatic control system designed for linearity, has a housing (1) immersed in a cold source (11), heated by a resistor (12) alongside a sensor (13) connected to a probe (2) with a controller (20) attached, and with a circuit between the probe and the heating resistor, having three arms, each with its own potentiometer (30, 32, 34). The first one is in series with a proportional amplifier (31), the secondone in series with an integrating amplifier (33), and the third one with a drift amplifier (35), all connected to a separating amplifier (37) followed by a lineariser (4) and an output amplifier (50). The lineariser includes an input device with parabolic response. The sensor (13) is preferably on gallium arsenide NTC diode.
