Single Pressure Switches
EXPLOSION-PROOF DIAPHRAGM OPERATED PRESSURE SWITCHES
Visible Setpoint, Fixed Deadband, Pressure Ranges to 1400 psi
The SERIES 1000E has the same rugged construction as used in Series 1000W plus
explosion-proof design are combined in this new unit. UL listed for Class I, Groups A,
B, C & D; Class II, Groups E, F & G. Bellville spring movement permits mounting of
control in any position and helps prevent contact chatter. High over-pressure protection
and vibration resistance are also featured.
