CVM201 Sensor

CVM201 Built-in Controller with OLED Display

The sensor inside CVM201 Super Bee™ module incorporates
numerous design enhancements compared to other
traditional convection vacuum gauges.

The InstruTech CVM201 Super Bee provides the basic signal
conditioning required to turn the gauge into a complete
measuring instrument. Similar feature filled design philosophy is
incorporated into the module electronics. The CVM201 Super
Bee provides non-linear or log-linear and linear analog outputs,
two setpoint relays and RS232/485 serial communications. A
built-in OLED digital display provides the measured pressure
values and provides for a convenient user interface for setup and
operation of the vacuum gauge.

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
convection enhanced Pirani vacuum gauge with significant
cost savings that are passed on to the user.

The biggest cost savings is from manufacturing a single model,
with all possible options, instead of making dozens of different pc
boards and models. And you don't have to give up one feature to
get another you want.
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 CVM201 Super Bee offers a
cost-effective solution for your vacuum gauging needs.

Also a direct drop-in plug-compatible replacement for the Mini-Convectron®
The InstruTech CVM201 Super Bee module will also directly
replace most Granville-Phillips® Mini-Convectron® modules.
The InstruTech Super Bee provides equivalent or better
performance throughout the range of 1 x 10-4 to 1,000 Torr.
Linear and non-linear analog signals, digital interfaces, and
setpoint relays are all included in the standard InstruTech
module. All are identical to their corresponding MiniConvectron® functions. Software commands are the same.

One InstruTech CVM201 Super Bee can directly replace dozens of
different Mini-Convectron® configurations, reducing the number
of spares you need to keep on hand.
The 9-pin D-sub and 15 pin D-sub connectors have the same
pinouts and signals as the corresponding Mini-Convectrons®.
With Super Bee’s performance, more robust design, longevity,
and lower cost, your process will only improve.
