Four styles to choose from PX309 Cable Connection PX319 DIN Connection Style (mating connector included) PX329 Twist Lock Connection (mating connector sold separately) PX359 with M12 Connector (mating cables sold separately)
STATE-OF-THE-ART TECHNOLOGY OMEGA’s PX309 Series high performance general purpose
pressure transducers use two state-of-the-art silicon technologies.
Pressure ranges below 100 psi use a high-accuracy
silicon sensor protected by a fluid filled
stainless steel diaphragm. Ranges
100 psi and above use high-accuracy silicon strain
gages molecularly bonded to the stainless steel diaphragm.
Both systems provide a rugged sensor with high accuracy and excellent long term stability.
FAST DELIVERY ON MOST MODELS! Typical Lead time is 4-weeks or less if not in stock.
