Compact flow sensors for hygienic areas


The flow sensors of the SI6 series serve to monitor liquids and gases in pipes in the food and beverage industry. Thanks to a broad selection of process adapters, the sensors can be used in nearly all applications.
The robust stainless steel housing with protection rating IP 67 / IP 69K is suited for use in harsh environments. The sensors can be used at medium temperatures up to 120 °C.
The flow range and the switch points are adjusted using a pushbutton on the unit. A multicolour LED display indicates the nominal flow range and the switch point.
Electronic locking of the settings prevents unintentional maladjustment. The possibility of restoring the factory settings provides additional safety.
