WIKA Model PGS21 Bourdon tube pressure gauge with switch contacts
$120.00
The WIKA PGS21 is a Bourdon tube pressure gauge with integrated switch contacts, designed for pressure monitoring and control in industrial applications. It combines the reliability of traditional mechanical pressure measurement with the ability to trigger external devices or alarms when specific pressure thresholds are reached.
Typical Applications:
• Pressure monitoring and control in hydraulic and pneumatic systems
• Industrial processes requiring pressure-based switching actions
• HVAC and refrigeration systems
• Water and wastewater treatment plants
• Pump protection and safety monitoring
Not Recommended For:
• Applications requiring continuous data transmission or remote monitoring
• Hazardous environments without appropriate protective measures (e.g., ATEX)
Selection Notes:
• Ideal for applications where pressure monitoring is required with the added functionality of switch contacts for process control
• Available with adjustable switch points to set when the switch contacts activate (e.g., alarm, shutdown, or valve control)
• Suitable for both low and high-pressure ranges, depending on your application needs
• Available in various configurations for easy integration into control and safety systems
Why Choose the WIKA PGS21 Bourdon Tube Pressure Gauge with Switch Contacts
• Dual functionality: provides both pressure indication and switch contact output for control and safety actions
• Adjustable switch points allow for flexible control, such as triggering alarms, activating pumps, or shutting down processes
• Long-lasting, robust Bourdon tube technology for accurate and stable pressure measurement
• Low maintenance and easy calibration, reducing downtime and maintenance costs
• Suitable for a wide range of industrial applications, including hydraulic, pneumatic, and chemical processes
• Can be used for both safety and process control in critical applications, such as pump protection or overpressure shutdown
