Differential Pressure 0.5 to 3.5 Bar
苏州乡林楼宇智能科技有限公司 李小姐 13151177225 GENERAL
The PF21differential pressure switches have
been designed for most industrial pressure
measurement applications where considering
the quality performance, reliability and low cost.
The separated diaphragm design and brass
connection can be used for gas and liquid
applications.
The precision snap-acting switches provide a
narrow dead band and repeatability. A
convenient, externally accessible adjustment
screw is multi-turn to provide easy set point
adjustability.
FEATURES
• Fluid and Gas applications
• Adjustable Switch Setting Point
• Differential Pressure 0.5 to 3.5 Bar
• 5A@125/250 VAC SPDT Switch
• Compact construction
• Shock and vibration resistance
• Terminal block wiring
