Model KX Flush Mount Pressure Transducer
APPLICATIONS:
Pulp/paper, waste water, spray booths
and all heavy medium and pumping
processes
FEATURES:
Available with PMC adapter (shown)
•
• Flush-mounted integral 316 stainless
steel diaphragm
• Stainless steel NEMA 4X enclosure
• Current/voltage output
The Ashcroft®KX transmitter combines
the proven benefits of poly-silicon thin film
performance with the utility of a flushmounting sensing diaphragm. Modern lowpressure chemical vapor deposition methods provide simple, stable molecular
bonds between the metal diaphragm and a
polysilicon strain gage bridge. There are
no epoxies or bonding agents to contribute
to signal instability or drift.
The flush sensing element is provided by
an integral, silicone filled stainless steel
diaphragm seal. The small sensing area
and low internal volume ensure accurate
measurement under severe conditions.
The polysilicon strain resistors combine
very low noise levels with very high signal
output. The integral metal diaphragm and
polysilicon bridge are virtually unaffected
by shock, vibration or mounting position.
These transmitters are offered in many
standard pressure ranges with either current or voltage output signals. Transmitter
performance is directly traceable to the
National Institute of Standards and
Technology.
