The Series 102 & 1102 Flanged Chamber Type Level Controls are external cage type level switches which are self-contained in a side mount body. The sturdy 102 Series operates at pressure to 400 psi (28 bar) and temperatures to 425°F (218°C). The 102 Series will operate to a minimum specific gravity of 0.60. The 1102 Series will operate to a specific gravity of 0.40 under the same operating pressure and temperature. The 102 and 1102 Series contain a stainless steel float and offer a choice of cast iron, cast steel, or inexpensive cast 316 SS float chamber. These series are well suited for applications where ease of accessibility is desired for pressure or vacuum vessels. Electrical circuits using hermetically sealed snap action or mercury contacts are available in a variety of actions including SPST, SPDT, DPDT and DPST combinations. Optional circuits are available for low current, low voltage direct circuits; high direct current or high temperature applications. Electrical enclosures provide general purpose; weatherproof, explosion-proof or explosion-proof/vapor proof capability. The 102 design also features three 1″ NPT process connections for side/side or side/bottom piping. When using the side/side process connection, the bottom 1″ NPT connection can be used as a drain.

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.

The Series 123 & 125 Boiler Water Level Controls are designed for boiler applications, the 123 is primarily used for low water cut-off or feed-water control. Other applications include condensate tanks and deaerators. A special snap action switch mechanism eliminates frequent operation due to surging water level. A transparent cover provides convenient visible operation of the switch. Features a flanged chamber for easy clean out and replacement of float or switch mechanism without removing the unit from piping. The 125 offers the same long lasting service with a direct action mercury switch movement that provides a close deadband where needed.

Long life and reliable operation is inherent in the design of the 201 series. The heavy duty welded carbon steel chamber provides a control to operate up to 1000 psi (69 bar) and process temperature up to 750°F (400°C), 400°F (205°C) at the electrical head assembly. The use of an external magnet reduces the possibility of magnetic particle build up inside the armature tube and subsequent loss of operation as may occur with the internal magnet repulsion design. Choice of construction provides equipment suitable for specific gravity as low as (0.60). Electrical requirements are met by use of hermetically sealed snap action or mercury switches in a variety of actions including SPST, SPDT, DPDT and DPST arrangements. Optional circuits are available for low current/voltage DC; high current DC; or high temperature applications. Standard process connections are combination 1″ NPT and 1″ socket weld hubs. Flanged connections are offered as an option.

The Model DBLM Mini-Bin Dry Bulk Level Monitor provides reliable level sensing for dry bulk solids where mounting space is limited. Model DBLM Mini-Bin operates by using a 1 rpm synchronous motor to rotate a four vane, plastic paddle, and when material surrounds paddle and impedes rotation, the motor is de-energized and triggers a SPDT snap switch. Mount the Mini-Bin with optional 1-1/4″ to 3/4″ reducer to replace standard size units.

Rugged and reliable the Series L4 Flotect® Float Switch operates automatically to indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or actuating level alarm signals. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, the free-swinging float attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm. Float arm hinge design limits the arm angle to prevent vertical hang up.
