TriMod Besta

ABLE Instruments are an Official UK Representative for TriMod Besta Float Level Switches, a Swiss-engineered range of modular level control devices trusted by industry worldwide for over 50 years.

TriMod Besta, part of the Baumer Group, designs mechanical float switches that offer precise and reliable point level detection in a wide range of liquids. Their success lies in a unique modular approach, where each switch is built from three core components: a mounting flange, a float module adapted to the process medium, and a switch housing, either electric or pneumatic. This flexible architecture allows for easy customisation, reduced maintenance costs, and reliable integration into existing systems.

Besta float level switches are available in a wide variety of materials and configurations, including stainless steel, brass, and corrosion-resistant plastics. They support vertical or horizontal mounting, and are suitable for open or pressurised vessels. With models capable of operating at up to 100 bar and 400 °C, the range covers everything from standard industrial use to demanding marine and hazardous environments.

Common applications include chemical processing tanks, steam boilers, oil reservoirs, and clean water systems. Besta also supplies specialised models with international marine approvals such as DNV, Lloyd’s Register, and Bureau Veritas, as well as ATEX and IECEx-certified versions for use in explosive atmospheres.

TriMod Besta’s durability, switching precision and configurable design make it a preferred choice for OEMs and maintenance engineers alike. The range is supported by a full set of accessories, including float chambers, counterflanges, test actuators, and spare modules, all of which ABLE Instruments can supply and advise on.
