MAGNETROL T52-1E2A-BKP

Side Mounting
Liquid Level Switches
DESCRIPTION
Magnetrol side mounting controls mount horizontally to
any tank or vessel through a threaded or flanged pipe
connection. Standard models are normally equipped
with a single switch mechanism for high or low level
alarm or control applications. Tandem models, with two
switch mechanisms, are available for two-stage
applications.
FEATURES
• Body material of cast iron, carbon steel or
stainless steel
• 300 series stainless steel float and trim
• Threaded or flanged mounting
• Specific gravity ratings down to 0.50
• Process temperatures to +1000° F (+538° C)
• Choice of float size:
• 21⁄2" (64 mm)
• 21⁄2" × 4" (64 × 102 mm)
•
•
•
3" (76 mm)
31⁄2" (89 mm)
3" × 5" (76 × 127 mm)
• Field-adjustable level differential
• Choice of switch mechanism:
Dry contact
Hermetically sealed
Pneumatic
• Choice of switch mechanism enclosure:
NEMA 1 carbon steel for pneumatic
TYPE 4X/7/9, Class I, Div. 1, Group C & D,

APPLICATIONS
• Fuel tanks
• Day tanks
• Flash tanks
• Scrubbers
• Cooling towers
• Dump valve controls
• Condensate receivers
• Boilers
• Deaerators
• Holding tanks
TECHNOLOGY
Snap
switch
Side mounting units employ permanent magnetic
force as the only link between the float and the
switching element. As the pivoted float follows
liquid level changes, it moves a magnetic sleeve
into or out of the field of a switch actuating
magnet causing switch operation. A nonmagnetic barrier tube effectively isolates the
switch mechanism from the controlled liquid.

IEC Installation Instructions:
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
For ambient temperatures above +55° C or for process temperatures above +150° C, suitable heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
Special conditions for safe use:
When the equipment is installed in process temperatures higher than +85° C the temperature classification must be reduced
according to the following table as per IEC60079-0.
