The HYDAC flow switches of the HFS 2500 series are based on a position-independent float transmitter measurement principle.
The test medium moves a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted outside of the device and thus also outside of the flow circuit. When the magnet inside the float reaches the preset position, the reed contact switches.
In order to protect it against external influences, it is cast in a steplessly adjustable housing.
The devices of the HFS 2500 series are available in two variants, one with 5% accuracy and one with 10% accuracy of the end value.
Areas of application can be found in the monitoring of flow rates of fluid media (water / water-based), in the following areas, among others:
- Cooling systems and circuits
- Hydraulic systems
- Pumps
- Welding machines and laser plants
- Medical technology
- Pharmaceutical industry
- Chemical industry
- Research and development
- Accuracy ± 5% or ± 10% FS
- Free choice of installation position
- High functional dependability
- High switching accuracy
- Stepless switching point adjustment by the user
- High pressure resistance
- Screw connection
- ATEX version also available for explosion-hazard areas.
