A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control - for example, in the case of Volume Control Dampers. [1] Its operation can be manual or automatic. Manual dampers are turned by a handle on the outside of a duct. Automatic dampers ...
The Honeywell T87 Round Thermostat is a thermostat that Honeywell International, Inc. first manufactured in 1953. [1]
The control air typically is maintained on "mains" at 15-18 psi (although usually operable up to 20 psi). Pneumatic thermostats typically provide output/ branch/ post-restrictor (for single-pipe operation) pressures of 3-15 psi which is piped to the end device (valve/ damper actuator/ pneumatic-electric switch, etc.). [11]
The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
An actuator translates such an input signal into the required form of mechanical energy. It is a type of transducer. [2] In simple terms, it is a "mover". An actuator requires a control device (which provides control signal) and a source of energy.
Honeywell was a component of the Dow Jones Industrial Average index from 1999 to 2008. Prior to 1999, its corporate predecessors were included dating back to 1925, including early entrants in the computing and thermostat industries. [7] [8] In 2020, Honeywell rejoined the Dow Jones Industrial Average index. [9]
On August 16, 1892, the stockholders of the Electric Thermostat Company BBC agreed to sell an extensive list of patents to W.R. Sweatt for the sum of $1.00. On October 5, 1892, the directors changed the name to the Electric Heat Regulator Company , recapitalized it, and elected William Sweatt as both Secretary and Treasurer.
