Adjustable Pressure Switch, 0.2–400 Bar, NO/NC

The SUCH adjustable pressure switch uses a diaphragm or piston to detect pressure changes and actuate a microswitch when the preset pressure is reached. It covers pressure ranges from 0.2 to 400 bar and features SPDT contacts and IP65 protection. Adjustable hysteresis accommodates different switching requirements, while a service life of up to 1 million cycles supports repeated pressure control in water, oil, and gas systems.

Note: This pressure switch uses adjustable hysteresis to define the pressure difference between switching points in industrial control systems.

Feature

• Offers pressure ranges from 0.2 to 400 bar to accommodate different industrial pressure control requirements.
• Uses SPDT contacts to support normally open and normally closed switching in control and alarm circuits.
• Withstands damage pressures of up to 900 bar on specified models.
• Provides adjustable hysteresis to suit different switching cycles and help reduce unwanted repeated switching.
• Features IP65 protection against dust and water jets for use in suitable industrial environments.
• Supports up to 1 million switching cycles for long-term pressure control applications.

Wiring

Adjustment

• Step 1: Remove the DIN Connector
  Use a screwdriver to loosen the retaining nut and remove the DIN connector.
• Step 2: Adjust the Pressure Setpoint
  Use the supplied hex key to adjust the setpoint. Turn clockwise to increase the setpoint or counterclockwise to decrease it. Do not twist the DIN connector during removal, as this may damage the internal wiring.
• Step 3: Set the Pressure Setpoint
  The pressure switch is typically factory-set to the specified pressure. For on-site adjustment, monitor the system pressure using a pressure gauge. For example, to trigger an alarm at 10 bar, adjust the setpoint until the switch activates the alarm at the indicated pressure.
