Features
•
Low cost, direct drop-in plug-compatible replacement for GP
Mini- Convectron
®
modules.
•
Built-in digital display, two setpoints, log-linear, linear, and
nonlinear analog outputs, and RS232/485 interface are all
included in the InstruTech CVM module product line.
•
Wide measurement range 10
-4
to 1000 Torr.
•
Gauge tube and electronics in one convenient package
T
he InstruTech CVM-201 module provides the basic signal
conditioning required to turn the gauge into a complete
measuring instrument, the CVM-201 “Super Bee” module
provides non-linear and linear or log-linear analog outputs,
RS232/485 interface, and two setpoint relays. A built-in display pro-
vides a convenient user interface for setup and operation of the
vacuum gauge.
Direct drop-in plug-compatible replacement for the
GP Mini-Convectron
®
The InstruTech CVM-201 module will directly replace most
Granville-Phillips Mini-Convectron modules. Linear and non-linear
analog signals, digital interfaces, and setpoint relays are all includ-
ed on the standard InstuTech module. All are identical to their cor-
responding Mini-Convectron functions. Software commands are
the same.
GP Mini-Convectron modules use either 9-pin D-sub or 15-pin
high-density D-sub connector, with 6 different pinout configurations,
depending on model and options. If you have more than one vacu-
um system, you probably have several different Mini-Convectron
models to support. The CVM-201 uses both a 9-pin D-sub and a
15-pin high density d-sub connector to bring out all these functions
in the same pinout configurations.
Lower cost without sacrificing quality or
functionality
InstruTech has made numerous changes to reduce cost and
improve performance.Temperature compensation has been moved
out of the vacuum environment, significantly reducing costs and
improving performance. The gauge is bakeable to 1508°C (elec-
tronics removed) and shielded against RF interference. A fine mesh
screen in the gauge port helps prevent particulate contamination
from entering the gauge. The sensor is far more reproducible and
easier to make. These, and other improvements add up to signifi-
cant cost savings to you. Similar improvements have been incor-
porated into the module electronics. The biggest cost savings
comes 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 can have
an analog output with an RS485 interface or a linear output with
setpoints, or an RS485 interface with a display. The standard
InstruTech module includes all these features at a cost comparable
to the most basic model Mini-Convectron
