Product catalog summary

Pressure Switch Instructions Summary

Specifications:
- Operating Pressure: Ranges from 0.03 to 100 bar, with maximum overpressure limits varying from 2 to 100 bar.
- Operating Temperature: Varies by type, from -30°C to +150°C.
- Media Temperature: -25°C to +85°C.
- Storage Temperature: -25°C to +70°C.
- IP Protection: IP65.

Electrical Connection:
- Micro switch can be connected as cut-in, cut-out, or change-over switch.
- Terminals 2-1 open at pressure rise; Terminals 1-4 close at pressure rise.

Setpoint Adjustment:
- Dial accuracy is ±2% of the range.
- Fixed Differential: Adjust upper switching point with range spindle, lower point is fixed.
- Variable Differential: Adjust lower and upper switching points using range spindle and differential adjusting screw.

Installation:
- Avoid holding the housing while tightening the pressure connection to prevent altering the sensing element adjustments.

Additional Information:
- Torque moment for pressure connection is max. 25Nm.
- Various connection types and dimensions are specified for installation.
