How to Adjust the Hysteresis Value of a Digital Pressure Switch?

How to Adjust the Hysteresis Value of a Digital Pressure Switch?

Enter Setup Mode?

Press the ?"S"? or ?"SET"? key to access the parameter configuration interface.

Navigate to the ?hysteresis setting? (labeled as ?"H-1"? or ?"Hys"? in some models).

Adjust the Hysteresis Value?

Use the ?▲/▼? keys to modify the hysteresis value (e.g., from ?3? to ?2?).

Confirm changes by pressing ?"S"? or ?"ENTER"? to save settings.

Test the Functionality?

Apply pressure to verify the switch behavior:

Above the set threshold (e.g., 50 bar)?: Output signal activates (indicated by a ?green display?).

Below the threshold (e.g., 48 bar)?: Signal deactivates (indicated by a ?red display?).

Additional Considerations?

Hysteresis Mode Selection?: Some models offer ?window comparison? or ?single-point mode?; choose based on application needs.

Unit Consistency?: Ensure pressure units (e.g., ?bar, MPa, psi?) match system requirements.

Key Notes?:

Hysteresis prevents ?frequent switching? by introducing a deadband between activation and deactivation pressures.

For precise control, calibrate the sensor before adjusting hysteresis.
