DOUBLE BELLOWS DIFFERENTIAL PRESSURE SWITCH

Visible Set Points, Adjustable or Fixed Deadband, High Pressure Ranges

Two opposing bellows combine maximum sensitivity and vibration resistance at a

moderate cost in the Series DP Double Bellows Differential Pressure Switch. Both

set and reset points are easily adjustable through non-interactive, externally accessible controls. Visible set point indicators simplify changes. SPDT snap action switch, 316 stainless steel or brass bellows, anged steel housing. Rated pressures to 600 psig.

FEATURES/BENEFITS

• Bellows switch design provides sensitivity to pressure changes but resists vibration preventing out of range switching

• External access to set and rest controls makes for easy adjustments

• Visible set point indicators simplify changes

APPLICATIONS

• Accurate switch triggers in high pressure applications
