SERIES DP
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.
BENEFITS/FEATURES
• 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
