PS
DIFFERENTIAL PRESSURe switch
PS
The PS is a robust, easy-to-use differential pressure switch for air and non-combustible gases.
USAGE
The pressure switches are used in ventilation and air-conditioning systems to monitor changes in overpressure, vacuum and differential pressure.
​
APPLICATIONS
• monitoring filters and fans
• monitoring vacuum and overpressure in air ducts
• controlling defrosting functions
