P233 Adjustable differential pressure switch

Hàng hot: | Lượt xem: 60

Danh mục : Others
Nhãn hiệu : Johnson Controls

This switch senses a change in the (differential) pressure as the airflow changes. The (differential) pressure is applied to the two sides of a diaphragm in the control. The spring-loaded diaphragm moves and actuates the switch. The series P233A/F can also be used to detect small positive gauge pressure or to detect a vacuum.
