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.
