Honsberg - FF Series Flow Switch

Piston

The Honsberg FF series flow switch is a simple unit which indicates when a specific flow rate has been acheieved. The basic operation of the switch is when the volume flow raises a piston (fitted with a magnet) out from a valve seat which is against a spring force and when the specificed flow rate is achieved the piston actuates an hermetically separated reed switch. The FF is designed for horizontal inwards flow; switching head not recommended underneath; other installation positions are possible; the installation position affects the switching point and range.

 

*The switch point must always be specified/factory-set item

  • Adjusted switching value
  • Highly reproducible
  • Insensitive to dirt
  • Adjustment for oil or gas
  • Special values

Ordering information

*The switch point must always be specified/factory-set item

 

  • Specify direction of flow, medium, and switching point.
  • For oils, state viscosity, temperature and designation (e.g. ISO VG 68) (enquire about range).
  • For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (enquire about range).

 

 

Installation

  • Include straight calming section of 5 x DN in inlet and outlet.
  • If the media are dirty, install a filter (use magnetic filter for ferritic components).
  • It must be ensured that the values given for voltage, current, and power are not exceeded.
  • When switched on, a load must be connected in series. The electrical details apply to ohmic loads. Capacitive, inductive and lamp loads must be operated using a protective circuit.
  • Standard: horizontal inwards flow; switching head not recommended underneath; other installation positions are possible; the installation position affects the switching point and range.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks

Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure. The kind of faults that are frustrating to trace and expensive to fix.
Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
