CVM211 Sensor
The sensor inside the CVM211 Stinger™ module
incorporates numerous design enhancements compared
to other traditional convection vacuum gauges.
Temperature compensation has been moved out of the
vacuum environment and placed around the outside of
the vacuum gauge tube. This has eliminated a dozen or so
unnecessary parts and welds, significantly increasing the
reliability, providing optimal vacuum measurement while
reducing cost. The improved mechanical strength results
in a highly robust vacuum gauge less susceptible to
mechanical shock and vibration.
Other design features include reduced internal volume
and significant reduction of internal surface area resulting
in faster pump-down and less outgassing. A fine mesh
screen in the gauge inlet port helps prevent particulate
contamination from entering the gauge. The gauge is
shielded against RF interference.
These, and other, design features add up to a highly
reliable vacuum gauge with significant cost savings that
are passed on to the user.

CVM211 Built-in Controller & Display
InstruTech's CVM211 Stinger module provides the
necessary signal conditioning to turn the convection gauge
into a complete vacuum measuring instrument.
The CVM211 Stinger module provides one log-linear or
non-linear analog output and one setpoint relay. In
addition, a built-in display provides the measured pressure
values and provides a convenient user interface for setup
and operation of the vacuum gauge.

Low-cost upgrade
for thermocouple TC vacuum gauges
The CVM211 Stinger provides a wider measuring range than
traditional thermocouple vacuum gauges - from 1 x 10-4 Torr
to above atmosphere - so you can monitor your entire
pump-down and vent cycle.
The CVM211 Stinger convection enhanced Pirani gauge is
more accurate than a thermocouple gauge, especially at
lower pressures. And depending on your gauge/readout
configuration, the cost of a Stinger is about the same cost of
a TC gauge system.

Also a direct drop-in replacement
for Mini-Convectron®
The CVM211 Stinger can also directly replace the most basic
Granville-Phillips® Mini-Convectron® modules, at
significantly lower cost. The InstruTech Stinger provides
equivalent or better performance throughout the range of
1 x 10-4 to 1,000 Torr.
The 9-pin D-sub connector has the same pinouts and signals
as the corresponding Mini-Convectrons®. The non-linear
analog signal and setpoint relay are identical to their
corresponding Mini-Convectron® functions. With Stinger's
performance, more robust design, longevity, smaller size,
and lower cost, your process will only improve.

Guided by our vast experience and vacuum measurement
know how, InstruTech sensors are specifically designed for
optimum reliability and performance. Whether you're
looking to reduce costs or improve your process, the
CVM211 Stinger offers a cost-effective solution for your
vacuum gauging needs.
