Besta's modular design is a unique deviation from conventional level switch construction. This modular system allows individual and numerous combinations of float, flange and switch modules to suit your specific requirements. Switch modules are available with electric, electronic or pneumatic output signals. Switch housings are standard to IP65 enclosure, but depending on environmental conditions IP67 or IP68 must be chosen. For hazardous areas, hermetically sealed microswitches, flameproof housings or pneumatic switch modules can be used.
