TEMPERATURE REGULATOR Russian patent published in 1998 - IPC

FIELD: automatic control systems, in particular, for air cooling and ventilation, heating and hot water supply. SUBSTANCE: device has two channels for non- static temperature regulation, which have serial circuit of resistive thermometer, measuring bridge circuit, voltage amplifier, positional relay, gate and final-control unit. In addition device has pulse chopper, which output is connected to input of gate, two- position temperature control channel, which has serial circuit of resistive thermometer, measuring bridge circuit, voltage amplifier, comparator with given rectangular hysteresis loop and gate. Outputs of reference voltage source are connected to inputs of measuring bridge circuits, positional relays and comparator with given rectangular hysteresis loop. EFFECT: increased functional capabilities. 1 dwg
