The Series
626 Pressure Transmitters possess a highly
precise 0.25% piezo-resistive sensor contained in a compact,
rugged, NEMA 4X stainless steel general purpose housing
or cast aluminum conduit housing.
The Dwyer
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 highly corrosive 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 ranges of vacuum, compound to 5000 psi with
a variety of optional outputs, process connections and electrical
terminations to allow you to select the right transmitter
for your application.
APPLICATIONS
- Compressors
- Pumping Systems
- Irrigation Equipment
- Hydraulic
- Industrial Process Monitoring
