| Overview The type TFS10-13 is a family of compact, precise flow switches. The flow switches is ideally suited for use in automation processes or other industrial applications where liquid media must be monitored. The sensor works according to the calorimetric measuring principle, fully electronic and without mechanically moving parts. It detects the flow velocity of the medium and converts it into an electrical signal. •precise switching flow monitor •high switching accuracy even with slower flows •separate adjustment of set point and range •display of the flow and the switching point via LED chain •LED for output status •robust industrial design (special encapsulation) •Anti scaling •ISO 9001:2015 |
