SR
• PRESSURE SENSOR
The Model SR is intended for OEM’s requiring
a small pressure sensor with high pressure capability
and superior corrosion resistance. Constructed of
a brazed assembly of 300 series stainless steels, the
SR can tolerate a wide variety of corrosive media
without risk of leaking.
The SR’s design provides high working pressures
and high overload and burst pressures at no extra
cost. The sensing elements are isolated from the
media without using oil-filled isolation technologies.
Unlike other low cost sensors, the SR’s output
is compensated for changes in temperature.
