Suitable Applications for the DS 230 Electronic Pressure Switch
The DS 230 is ideal for OEMs who need a compact, configurable pressure switch with local display and optional analog feedback. Its fast switching, robust burst/overpressure ratings, and rotatable form factor suit a wide variety of automated systems.
- Pneumatics: Manifolds, actuators, air preparation units, leak testing, and compressed air skids.
- Pumps and Hydraulic Machines: Pump protection, pressure limiting, interlocks, and process feedback.
- Industrial Automation: Packaging machines, fillers, presses, and general machine control.
- Process Skids: OEM compressor units, filtration modules, and utility skids needing local indication and PLC integration.
- Test Benches: High-speed switching for pressure cycling, endurance testing, and proof testing within range limits.
- HVAC and Refrigeration: High/low pressure protection, line pressure monitoring, and safety cut outs (materials/media permitting).
