FORCED CUT IN CUT OUT TEMPERATURE CONTROLLER OF EMERGENCY DEVICE USED FOR MEASURING AND CONTROLLING TEMPERATURES Russian patent published in 2002 - IPC

FIELD: instrumentation. SUBSTANCE: invention relates to emergency devices designed for measuring and control of ambient temperatures. According to invention, emergency device temperature controller provides automatic continuous checking and maintaining preset ambient temperatures at points below emergency operation temperatures and increases degree of protection from emergencies. Free end of change-over lever acts directly onto emergency cut out contact spring and through spring, which can be adjusted by screw setting automatic maintenance of temperature owing to its axial displacement in nut rigidly coupled with spring, acts onto additional contact spring of microswitch. Lip of additional contact spring thrust against body, thus building springing force to contact group of microswitch. Movable contact of microswitch contact spring can occupy extreme lower position only above self-reset point. EFFECT: enlarged functional capabilities of temperature controller, improved protection against emergency situations. 1 dwg
