The PX835 explosion proof
pressure transmitter is ideal for
a broad spectrum of pressure
sensing requirements, requiring
approvals for explosion/flame proof.
The PX835 is designed with an all
welded stainless steel case and
manufactured to provide the user
with accurate, reliable, and stable
output data. This is accomplished
through the use of state of the
art sensor technology combined
with digital calibration to provide
extremely linear and precise
performance over the
entire specified pressure and
temperature range.
