With extremely rugged construction the SERIES 1000W provides excellent reliability in chemical, petroleum and industrial plants. Bellville spring movement permits mounting of control in any position and helps prevent contact chatter. New design also provides high over-pressure protection. Weatherproof housing is standard.

FEATURES/BENEFITS

• Weatherproof housing is ideal for a wide variety of applications where dust or water is present

• Spring movement design provides for control in any mounting position and prevents contact chatter reducing false or inconsistent switching

APPLICATIONS

• Chemical, petroleum, food and drug processing industries

• Process and Industrial applications
