Jacket insulation regulating device for e.g. tripper, has temperature sensors distributed in jacket, and solenoid valve between closed loop control system and air chamber supplied by hand pump, where chamber allows air admission in jacket

摘要

The device has a closed loop control system (1) connected to a temperature display (2) that is connected to temperature sensors (3) distributed in a jacket. A solenoid valve (4) is provided between the system and an air chamber (5) that is supplied using a hand pump (6). The valve is conditioned by a combined signal of the sensors. The air chamber permits the admission of air in the jacket.
