Description
Schneider Electric (Barber Colman) TK-2001 Pneumatic Temperature Controller is used for a control unit that has a direct-acting (DA) operation, a 60-90°F temperature range, and a 3-foot capillary, designed to control air temperature in HVAC systems using pneumatic control. It uses a liquid-filled sensor and a nozzle-flapper system to adjust the air pressure based on changes in temperature. It is attached to pneumatic lines and control parts, to ensure that it is properly coordinated in duct areas. It has a variable throttling range and proportional control action which ensure stable temperature control stable system balance.
