The switch points of the new WIKA model FSD-4 can be freely configured very easily via the 3-button operation directly on the instrument or optionally via IO-Link. The model FSD-4 can output both absolute values in various units and relative flow values and display them on the digital indicator.
For a wide range of applications
While a flow rate value is assigned to the first switch point, it can be defined at the second switching output whether the switch should switch at a second flow value or at a specific temperature value for the medium. In addition, the FSD-4 can be fitted with an analogue output for flow or temperature values. The wide range of parameterisation options makes the model FSD-4, with only three basic variants, an economical flow switch for a wide variety of applications and installation situations.
