For Powder & Bulk Solids

Be the first to review this product

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.

DIAPHRAGM SELECTION
A wide variety of diaphragms are available to match product bulk density, flowability, abrasiveness and temperature requirements while providing maximum sensitivity. The best choice for vessels subject to pressure or vacuum is “breathable” fabric (P Series), requiring no venting. Non-porous elastomer (G Series) type diaphragms are the best choice for more abrasive product and broader temperature range applications. Venting is always required with the G series and if used in pressurized vessels, venting to the tank atmosphere is required to allow pressure equalization. A slide rule “Diaphragm Selector” is available from the factory to help you choose the diaphragm best suited to your application.

FAQ

Questions

Question

What are the two dry product level switch model types? What ranges do they cover? How are they adjusted? How many set-points do they have?

Answer

GSD3DA - gravity (elastomer) suspension, aluminum housing, polyurethane diaphragm, standard 15 amp switch. PSD16A - pneumatic (fabric), suspension, aluminum housing, filter fabric diaphragm, polyester 150 micron permeability, standard 15 amp switch. They can be adjusted to any level. They are adjusted by a screw adjustment. One setpoint available. For additional options, you could look at our CLS2 Series Capacitive Level Switch, TFLS Series Tuning Fork Level Switch, PLS and PLS2 Series Paddle Level Switches.
