Pressure Switches

PSDA Differential Switch

Field Adjustable
De-zinc Bronze
Compact Size
Single Diaphragm
Differential from 2 – 67 psi (0.15 to 4.5 Bar)
System Pressures to 150 psi (10 Bar)
The PSDA differential pressure switch represents a breakthrough in low system pressure differential switches. The sensing diaphragm only operates when the difference between the High and Low rises or falls to the adjusted conditions.
