TEMPERATURE CONTROL AND SAFE DISCONNECTION DEVICE FOR ELECTROTHERMAL AND GAS EQUIPMENT Russian patent published in 2003 - IPC

Abstract RU 2208828 C2

FIELD: measurement technology and instrumentation engineering. SUBSTANCE: device that can be used in sensing relays for ambient temperature control and maintenance, as well as for safe disconnection of electric heating units, for example, cabinet ovens, waterheaters, and air-conditioners has two microswitches, switching lever, and safe disconnection lever for adjusting their relative position to temperature below starting point of flexible member when safe-disconnection contact group of microswitch opens; device also has safe- disconnection adjustment screw. Device incorporated provision for emergency operation in case of thermal system depressurization. EFFECT: enlarged stability of operating temperature variables; enhanced service life, enlarged functional capabilities of device. 1 cl, 1dwg
