FIELD: heating.
SUBSTANCE: invention relates to thermostatic systems and is meant for maintain the desired temperature of a heater; it can be used in food, chemical and other industries. Thermostatic system contains: sensor - thermistor with resistance of 24 k Ω, which is heat sensor and resistance box, all constituent of Wheatstone bridge, operational amplifier with a high amplification coefficient, transistor amplifier, heater, and controlled element - semiconductor switch. Design of the thermostatic system provides comparatively inconsiderable retention time for the specified temperature mode for about 8 seconds, maintaining the necessary temperature of the heater, with deviation from the specified value not more than ±0.1°C and can be used for making industrial gauges.
EFFECT: increased accuracy of maintaining desired heater temperature and also reduction of heater retention time for specified temperature regime.
