Possible areas of application
If you make exceptionally high requirements on monitoring of liquid flow, the SIKA turbine flow switch will be the correct selection.
Its areas of application: Monitoring of cooling circuits of highquality equipment like laser installations or HF generators. It avoids costly consequential damages resulting from overheating. A great number of different applications is covered by a very simple and exact selection of the set point. As an option, a pulse signal is also available in addition to the switching output (contact). In such a case, in addition to safe monitoring, a continuous or temporary measurement of the flow (e.g. for adjustment jobs) can also be carried out.
The core of the turbine flow switch is the extremely durable flow sensor SIKA-Turbotron which for years successfully demonstrated its reliability in many mass applications. It provides a flow-proportional frequency signal which is introduced to a microprocessor. This monitors the adjusted minimum flow and activates the electrically insulated alarm contact in the case of dwindling flow.
Even a due blocking of the turbine system is clearly recognized and reliably signaled. The adjustment of the set point can be carried out very easy and precisely. By means of a 16-position rotary switch (catching), the desired set point is selected.
