F4 Pressure switches. Use for liquid and gaseous fluids
Measuring range from 0,2 up to 400 bar 
Output signal SPDT  
Process connection R.1/8" or 1/4"  
Temperature 85°C
Degree of protection IP65

“F4” adjustable pressure switches allow a micro-switch commutation once a preset pressure value is reached. The set point is adjusted working on the central screw (P3 execution) or intercepting the regulation dowel situated inside the instrument, using a 2mm hexagonal key (M2 and M3).

 

Rotating clockwise the set point is increased and vice-versa is decreased. Mechanical stops protect both the spring and the micro-switch from over pressurization.

Available with the parts in contact with the fluid in stainless steel or brass.

 

  • Wide adjustment range
  • Used for pumps and compressors
  • Small footprint, easy installation.
