Description
DWYER Series E, G, & P ULTRA-MAG™ EXPLOSION-PROOF LEVEL SWITCH – For Powder & Bulk Solids
The Series E, G, & P Ultra-Mag™ is an explosion-proof series of level switches for powder and bulk solids that utilize a unique magnetic linkage and diaphragm design to sense the presence of powder and bulk solids in a variety of bins, vessels, and hoppers.
MOUNTING SELECTION. A choice of either suspension or flange mounting is available to match your application. Flange mounting is the best choice for control of low or intermediate level in vessels containing granular product that does not “bridge”, “rathole”, or otherwise build up on vessel walls. Choose suspension mounting for high level in vessels and for better operation with “bridging” product.
Note: The mounting configuration is represented by the letter “S” for suspension or “F” for flange which is the second digit in the part number.
Applications:
- Mining
- Food and beverage
- Silos
- Hoppers
Features:
- Uses a unique magnetic linkage which isolates the electrical compartment from controlled product, reducing maintenance and improving sensitivity
- Sealed switch compartment and sealed leads yield the exceptionally reliable operation
- A wide selection of diaphragms and switches is available with choices of flange or suspension mounting to fit a specific application
- Extremely sensitive indication and very economical
- Magnetic linkage makes this simple explosion-proof diaphragm switch the most rugged and reliable level control for a variety of products
