Honsberg - UR1 Series Flow Switch

Paddle

The Honsberg UR1 is a simple flow switch which can easily be adjusted and also changed from normally open to normally closed. The flow switch works via a spring-supported paddle which moves according to the flow and when the specific flow is reach a magnetic reed switch is activated.

Ordering information

Ordering information

 

● Specify direction of flow, medium, and switching range, UR1 or switching value UR2.

● For UR2 specify normally closed (n.c.) or normally open (n.o.).

● 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.
  • Include a filter if the media is dirty (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.
