Description
PK-250-SFG14-QSPKG/US/ /W
  • Simple switch point setting by means of two setting rings allowing optimum reading
  • High long-term stability thanks to robust stainless steel measuring cell with high permissible pressure rating
  • Mechanical locking prevents inadvertent switch point manipulation
  • Lifespan of more than 50 million pressure cycles
  • For use in hydraulics, pneumatics, air-conditioning and refrigeration
