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

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.
