Trimod´Besta Level Switch Options

In addition to the standard features of the Type A 01 051E15 level switch, Trimod´Besta offers a variety of options to meet specific application requirements:

Enhanced Protection:

• IP67 Protection: For applications demanding a higher level of ingress protection against dust and moisture, the level switch can be specified with an IP67 enclosure.

Material Options:

• Complete Stainless Steel Construction: For environments requiring the utmost corrosion resistance, the entire level switch, including the housing, flange, and wetted parts, can be constructed from stainless steel.

Flange Standards:

• Global Compatibility: Trimod´Besta level switches can be equipped with flanges that comply with various international standards, including EN/DIN, ANSI, BS, and JIS, ensuring compatibility with a wide range of piping systems.

Bellow Materials:

• Silicone, FPM, and PTFE: The standard Perbunan (Nitrile Butadiene Rubber) protective bellow can be replaced with alternative materials, such as Silicone, FPM (Fluorinated Rubber), or PTFE (Polytetrafluoroethylene), to suit specific temperature and chemical compatibility requirements:
  • Silicone Bellow: Provides enhanced temperature resistance up to +200°C (+392°F)
  • FPM Bellow: Offers superior chemical resistance to aggressive liquids
  • PTFE Bellow: Delivers exceptional chemical and temperature resistance, withstanding temperatures up to +250°C (+482°F)
