DWYER INSTRUMENTS 1950-5-2F Differential Pressure Switch, 1.4 to 5.5 Inch Size

Dwyer 1950-5-2F differential pressure switch is used to measure and control pressure differences between two points. It is specifically designed for applications where the pressure range falls between 1.4 and 5.5 inches of the water column.

Working Mechanism:

• When two separate pressure sources are connected across a sensing diaphragm, the pressure differential provides a force that acts on the pre-tensioned spring.
• This motion causes a balancing arm or mechanism to make the smallest movement necessary to activate the microswitch.

Features:

• Dwyer 1950-5-2F differential pressure switch has an explosion and weather-proof housing to protect it from harsh environmental conditions.
• It has a simple electrical connection that makes installation easy.
• This differential pressure switch has a set point screw that provides easy adjustments without disassembling the enclosure.
• It has an operating range of 1.4 to 5.5 inches of the water column.
• This Dwyer Instruments 1950-5-2F differential pressure switch has explosion-proof and weatherproof housing to sense a difference in pressure between two pressure sources.
• It is equipped with an external set point screw for providing easy access to simplify making adjustments without opening or disassembling the enclosure.
• This Dwyer differential pressure switch is CE, UL, CSA and FM approved for use in Class I, Div 1, Groups C & D; Class II, Groups E, F, & G; and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54).

Standards and Approvals:

• CE
• CSA
• FM
