Trimod Besta side mount float level switch

  • Heavy duty float switch
  • Versatile, three module ("tri-mod") construction
    • Easy to customise  & repair
  • Available with a range of approvals (e.g. IECEx, ATEX, etc), certificates (e.g. SIL1 & SIL2), reports (e.g. materials & functional tests) & marine insurer approvals (e.g. ABS, GL, DNV, Lloyd's etc)
  • Mounting: range of options
    • Typically via counter flange or directly to tank wall via bolts
    • Flanged units also available
  • Wetted materials: 316SS
    • Wide range of other materials including hastelloy-C available on request
  • Output: SIL1 SPDT microswitches are standard, but a choice of:
    • Gold contacts for low current, low voltage applications (e.g. simple device in intrinsically safe circuits)
    • Namur proximity switches
    • High temperature
    • IECEx Ex de
    • Pneumatic (on / off or proportional) - refer pneumatic models

  • Electrical connection: weatherproof (IP65), typically with M20 cable gland
  • Options:
    • Counter flange: weld to tank for easy mounting - available in 316SS & carbon steel
    • Test actuator: mechanical test actuator allows for testing of the switch during routine preventative maintenence
    • Pressure chambers: remove the float from inside the process tank - custom built to meet specific application needs
    • Top mount, bent rod & other configurations
  • Big range of units available ex. stock (e.g. AA 01 04, A 01 041, AA 01 093, AA 01 051E15, ZKK5 01 04) with many other configurations built next business day
