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

● 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.
