Brochure Shipbuilding solutions

Product catalog summary

Overview: The document provides detailed information on Trimod'Besta level switches used in the shipbuilding and marine industry. These switches are trusted for their reliability and versatility, with over a million installations worldwide since 1967.

Switch Modules: The switches are available in electronic, electric, pneumatic, and explosion-proof versions. They come with housings rated IP65, IP67, and IP68, made from aluminum and stainless steel.

Flange Modules: Flanges are available in various standards (JIS, ANSI, EN/DIN, BS) and materials (stainless steel, Hastelloy C, plastic), supporting pressures up to ANSI cl. 2500.

Float Modules: Designed for low-density liquids and high-pressure applications, these modules can be used horizontally or vertically and are made from stainless steel, Hastelloy C, and plastic.

Applications: Typical applications include fresh and waste water tanks, fuel oil tanks, bilge alarms, lubrication tanks, separation layer detection, balance tanks, inert gas production, and LPG/LNG tanks.

Technical Specifications: The switches have a nominal pressure of PN 25, minimum liquid density of 0.7 kg/dm³, and are made from seawater-resistant materials. They operate within ambient temperatures of -30 to 80°C and have a switch rating of 250 VAC, 5 A / 30 VDC, 5 A.

Installation: The simplest installation method is using standard weld-on counterflanges. Specific types are available for use with test actuators, allowing manual function checks of the level switch.

Test Actuator: Allows periodic manual checks of the switch's function, including the switching element and float movement.
