T E C H N O L O G Y
B40 level switches 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 ➀ into or out of the field of a switch
actuating magnet ➁ causing switch operation. A nonmagnetic barrier tube ➂ effectively isolates the switch
mechanism from the controlled liquid.

➀ 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.

PRODUCT DESIGN
Pressure vessels are designed within code specified
stress limits. Design calculations, design prints and weld
qualifications are available for audit. All chamber branch
and circumferential weld joints are designed to achieve
FULL penetration.
WELDING
All welding is performed by qualified welders and per
procedures required by the ASME Boiler Pressure Vessel
Code Sec. IX. Welds are visually inspected for FULL
penetration. All other non-destructive examination is
performed per ANSI B31.1.
MATERIALS OF CONSTRUCTION
All pressure-retaining materials are procured with
Certificates of Conformance to assure compliance of
components with required standards.
HYDROSTATIC TEST
All chambers are hydrostatically tested at 1.5 times the
design pressure.
