A flow switch with temperature monitoring

By Chemical Engineering |

The new model FSD-3 electronic flow switch with digital display (photo) was developed for applications using liquid media. Switching and analog outputs for flow, temperature and diagnostics enable strong versatility, says the manufacturer. The model FSD-3 can support process control in a number of ways: as a flow monitor, via the switching function; as a trend indicator for media flow, via the analog signal; and with integrated temperature measurement (–20 to 85°C). The optional diagnostic function acts on sensor defect (switching function), and whenever the measuring ranges for flow and temperature are exceeded (display indication). The new flow switch is easy to parameterize via the onsite display and an intuitive menu navigation in accordance with the VDMA standard. The FSD-3 functions on the calorimetric measuring principle, where the heat dissipation from a heated sensor is directly related to the flowrate. This method of measurement has no moving parts, so the flow switch operates wear-free. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
