Schneider Electric (Barber Colman) PNV-102 Diaphragm MK-2690

The Schneider Electric (Barber Colman) PNV-102 Diaphragm MK-2690 is used in a pressure-responsive regulator to monitor pressure changes in HVAC systems. It operates by deflecting as the pressure differs and transferring that flow to an associated switch or control in operation within air handlers and boilers. The diaphragm is mounted in the pressure-sensing chamber of a controller and attached to the control linkage. In reacting to pressure changes, this diaphragm assist in the proper control measures, secure operation, and consistent condition.
