They are mainly used for sensing a difference in pressure between two points in a plant or system. ( ) 11 6 ) 32 A particular design of the differential pressure switch is described below to illustrate the principle of operation. 6 2 )
) ) ( ( Piston design allows mounting in any orientation. The Differential Pressure Switch just like the pressure switch is a simple electro- mechanical device that operates on the basic principles of Levers and opposing forces. The LF32 is an adjustable differential pressure switch capable of detecting miniscule changes in pressure do to its size and proven design. ( ( The Differential Pressure Switch just like the pressure switch is a simple electro- mechanical device that operates on the basic principles of Levers and opposing forces. The two systems are constantly monitored, and their relative pressure is measured. 22 ( We Provide Tools and Basic Information for Learning Process Instrumentation and Control Engineering. General Fluids Pressure Switch⁄Sensor Low Differential Pressure Sensor Controller Air Catch Sensor Flow Switch⁄Sensor General Pneumatic Flow Switch⁄Sensor For Water Flow Switch⁄Sensor For DI Water and Chemicals Flow 9 22 A differential pressure switch is designed to sense a difference in pressure between two pressure sources in the plant for control purposes.
) 15 As shown in the diagram above, the pressure ports for high process pressure and low process pressure are separated by an It offers innovative solutions and components that meet the requirements of the most varied applications.Successful and enduring presence in North America, Europe, Asia, Australia and South America, further enhanced by the prestigious TUV ISO 9001: 2008 certification and many other specific product approvals, prove that Lefoo is a qualified international manufacturer capable of meet the most diverse and demanding technological requirements.We are focused on user-driven outcomes, we strive to create meaningful connections for users through considered strategy and innovation. 10

( ( 15 Three essential elements in the switch are used in various combinations to manufacture hundreds of variants of differential and pressure switches to suit a variety of industrial applications. When the differential pressure exceeds your setpoint, the switch is activated.

( ) 1 ) ( ( When the pressures from two different sources in a process are connected across the sensing diaphragm, metallic or elastomeric as the case may be, the pressure difference creates a force which then overcomes that of a pre-tensioned spring and in the process moves a balancing arm or mechanism to effect the minimal movement required to actuate the They are designed for HVAC, Energy Management, and Direct Digital Control (DDC) applications. 5 Switches are single pole, double throw (SPDT), so they switch one circuit on or off.

9 7 1 Offers field adjustments and can handle system pressures up to 6000 psig.
10 1 The switch set point or switching point can be field adjustable with out the need of a manometer by simply using the adjustment knob and the built in calibrated visual scale. (
