Weber Sensors 4120.52MA S110/67 Flow-Captor Flow Switch with LED Display and Stainless Steel Housing and 67 mm Sensor Head
- Part #:4120.52MA 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 controlled. The sensor operates according to the calorimetric (thermal) measuring principle, fully electronic and without any mechanically moving parts. The flow-captor detects the flow velocity of the medium and converts it into an electrical signal.
Features:
- Precise switching flow monitor with solid state relay output (SSR)
- High switching accuracy even with slower flows
- Separate adjustment of set-point and range
- Display of flow and the adjusted switching point via LED chain
- LED for output status
- Robust stainless steel design (special potting)
- ISO 9001:2015
