Series 626 & 628 Industrial Pressure Transmitter

Brand: Dwyer Instruments, LLC
Does not ship to OH, United States
The Series 626 Pressure Transmitters possess a highly precise 0.25% full scale accuracy piezo-resistive sensor contained in a compact, rugged, NEMA 4X (IP66) stainless steel general-purpose housing or cast aluminum conduit housing. 

The Series 628 Pressure Transmitters are ideal for OEMs with 1% full scale accuracy sensors. The transmitter is also available in the general-purpose stainless steel housing and the cast aluminum conduit housing.

The corrosion resistant 316L stainless steel wetted parts allow the Series 626 and 628 transmitters to measure the pressure in a multitude of processes from hydraulic oils to chemicals. 

The Series 626 and 628 are available in absolute and pressure ranges with a variety of optional outputs, process connections and electrical terminations to allow you to select the right transmitter for your application.

Note: The standard conduit housing (-CH) has been phased out, see the conduit box housing (-CB) for the replacement model.
Features
  • NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
  • Robust 316 Stainless Steel oil filled sensor provides shock and vibration resistance insuring stability in controlling pressure for process applications
  • A wide range of models and connections that can meet pressure measurement specifications from low to very high
