Description
The flow-captor type is used in automation processes and other industrial applications where liquid media must be monitored. The sensor works according to the calorimetric measuring principle and without mechanically moved parts. The flow-captor detects the flow velocity of the medium and converts it into an electrical signal.
Features:
- robust metal construction (M)
- plug design for Brad-Harrison coupling (S140)
- separate setting of "Range" and "Set-point"
- pressure resistant up to max. 100 bar
- analogue display of flow condition and switching point via LED chain
- ISO 9001:2015
