Test reports for customers

• SIKA test labs - many qualification tests Temperature shock Contamination and many other tests

• Sample devices can be supplied with works test certificate

Reliable partnership with SIKA

• More than 45 years of experience with flow sensors in heaters

• Leading heat pump manufacturers trust in SIKA Vortex flow sensors

General information on the principle of operation

Alternate vortices rotating in opposite directions are generated behind a bluff body immersed in a flow. The vortices detach from the edges of the bluff body and form a

Kármán vortex street in the fluid stream. The distance between the single vortices is constant. The frequency of the vortices flowing past a sensor depends on the flow rate

and is proportional to the flow. The sensor detects these vortices which are then converted to an electrical frequency signal.

• Minimal flow obstruction low pressure drop

• Independent of the conductivity of the medium

• High long-term stability / no zero drift

Reliable

• Piezoceramic sensor element completely encapsulated no direct medium contact dirt-resistant and fail-safe

• Robust metal body

• CE Marking

• OEM product developed and produced in Germany

Wiring

Pin assignmentThe pin assignment depends on the chosen configuration of the device.

Possible pin assignments:Pin 1: +UB

Pin 2: UFlow • RTemp • Analog U/IPin 3: GNDPin 4: Frequenzy • Analog U/I • Alarm*1

Pin 5: UTemp • RTemp

Wire the connecting cable according to your device version and the pin assignments shown on the type plate.

*1 The alarm output is only possible with the corresponding firmware and has been determined during the order.

GNDThe frequency output can be wired together with the optional functions. However, not every combination is possible.In principle, the pins 2, 4 and 5 can only be assigned with one function at a time. A multiple assignment is not possible.The wiring results from an overlay of the circuit diagrams of the corresponding functions, as shown in the two following examples.
