The WIKA PGS23.100, PGS23.160, PGS26.100 and PGS26.160 are Bourdon tube pressure gauges with integrated electrical contacts. The pointer displays the actual pressure, while adjustable contacts switch electrical circuits when the pressure reaches configured set points.
Key Features
- Dual function: Analog pressure display and electrical switching.
- Two dial sizes: 100 mm and 160 mm.
- Multiple contact options: Magnetic snap-action, reed, inductive and electronic contacts.
- Vibration resistance: Optional liquid-filled case for dynamic pressure loads and vibration.
- Safety options: Solid-front safety versions available.
- Digital identification: QR code provides access to instrument-specific information. WIKA
Suitable Applications
- Chemical and petrochemical plants: Pressure monitoring in process equipment.
- Power generation and mining: Pressure indication and switching for plant systems.
- Oil and gas installations: Local pressure readings and control-circuit activation.
- Industrial machinery: Pressure-dependent alarms and equipment control.
- PLC automation: Compatible electronic or reed contacts can provide switching signals to a PLC.
Technical Highlights & Selection Considerations
The main difference within this family is the instrument configuration and measuring-system design. When ordering, confirm:
- Model: PGS23 or PGS26, based on the required configuration.
- Dial size: 100 mm or 160 mm.
- Pressure range and connection: Match the process pressure, thread and mounting position.
- Contact type and quantity: Select the required switching function and number of set points.
- Operating environment: Check media compatibility, vibration, temperature and any hazardous-area approvals.
- Control-system compatibility: Verify contact ratings and electrical requirements, especially for PLC inputs.
The instruments are intended for gaseous and liquid media that are not highly viscous or crystallising. Confirm the relevant WIKA datasheet for exact model-specific specifications.
