The IS-20 series of intrinsically safe pressure
transmitters are designed for industrial pressure
measurement applications in hazardous
areas where intrinsically safe ratings are required.
The stainless steel wetted parts feature an
all-welded measuring cell for improved media
compatibility. There are no internal soft sealing
materials that may react with the media or
deteriorate over time.
The IS-21-S and IS-21-F transmitters feature
a flush diaphragm process connection. They are
specifically designed for the measurement of
viscous fluids or media containing solids that
may clog a NPT process connection.
Models IS-20-F and IS-21-F feature an integral
stainless steel junction box with internal terminal
block for use in extremely harsh environments.
A 1/2'' NPT female conduit connection is standard
on all models and a cable compression electrical
connection is available as an option.
All models require a 10 to 30 volt supply provided
by an intrinsically safe power supply or
through an approved intrinsically safe zener
