Pressure switch

Relative and absolutepressure switch
Type 529
The compact type 529 pressure switch is based upon the Huba
Control developed unique ceramic technology used for the last
20 years in millions of applications.
Switching points set in factory are available both N/C andN/O function. Various electrical and pressure connections areavailable to suit given applications.

Pressure range-1 ... 0 – 60 bar+ Compact, rugged construction+ Negligible temperature influence on accuracy+ Large selection of connections available.
+ Saving time by quick cable mounting by the customerwith swift connector

Function
N/C contact: When pressure is applied (p0  pmax) the switch will disconnect the applied load as soon as the upper switching point is reached.
As the pressure falls (pmax  p0) the switch will connect the load as soon as the lower switching point is reached.

N/C contact

N/O contact: When pressure is applied (p0  pmax) the switch will connect the applied load as soon as the upper switching point is reached.
With a fall in pressure (pmax  p0) the switch will disconnect the load as soon as the lower switching point is reached.
