Product catalog summary
Pressure Switch Technical Document Summary
Specifications:
- Operating Pressure: Ranges from 0.03 to 100 bar, with maximum overpressure limits varying from 2 to 100 bar depending on the specific range.
- Operating Temperature: Varies by type, with ranges from -30°C to +150°C.
- Media Temperature: Maximum of 25Nm torque moment for pressure connection.
- Storage Temperature: -25°C to +85°C.
- IP Protection: Rated at IP65.
Electrical Connection:
- The micro switch can function as a cut-in, cut-out, or change-over switch.
- Terminals 2-1 open with rising pressure, while terminals 1-4 close with rising pressure.
Setpoint Adjustment:
- Dial accuracy is ±2% of the range.
- Types with invariable differential: Adjust upper switching point using range spindle, lower point is fixed.
- Types with variable differential: Adjust both upper and lower switching points using specified screws.
Installation:
- Avoid holding the housing of the pressure switch while tightening the pressure connection to prevent altering the sensing element adjustments.
Additional Information:
- The document includes various types and models with specific pressure and temperature ranges.
- Contact information for Trafag AG is provided for further inquiries.
