Designed for heavy duty service,
OMEGA’s PX170 Series industrial
pressure transmitters utilize two of
our precision manufacturing
techniques. Low range, models to
50 psi gage and all absolute ranges,
use our precision CVD technology
which deposits an extremely durable,
precision solid state sensor directly
on small beam that is actuated by
the diaphragm. High range models,
above 50 psi gage, have the solid state
sensors sputtered directly onto the
diaphragm forming an extremely
rugged molucular bond.
These models are designed to
give long term stability and high
performance in industrial applications.
The low range models have ±0.5%
zero and ±1% span interchangeability
and the high range models have
±0.5% zero and span interchangeability.
All models have industrial RFI, EMI
and ESD protection and their solid
state construction give them long
life in high cycle applications,
typically 100M cycles.
