The WERT.I DPS107 series is an adjustable differential pressure switch for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-aggressive gases. It is suited to HVAC and energy-management applications, with automatic reset and field-adjustable switching points.
Key Features
- Easy switch-point adjustment by knob
- Transparent cover for set-point confirmation
- SPDT relay usable as N.O. or N.C.
- Minimum set pressure as low as 20 Pa
- Installer kit with PVC tubing included
