Weber Sensors 4120.12A S110/67 Flow-Captor Flow Switch Normally Closed, 2 Meter Cable (6 ft) Extended Length Sensor Head
- Part #:4120.12A S110/67
- Model #:Flow-Captor
- Condition:Brand New

The flow-captor 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. The flow-captor detects the flow velocity of the medium and converts it into an electrical signal.
Features:
- flow-captor type 4120.12 S110/67,
- normally closed
- 2 meter cable (6ft) extended length sensor head
- NPT Sensor head to be 67mm from hex to tip (1.45 inches) longer than standard length
- precise switching flow monitor
