Model 22
Ultra-Miniature Linear Vacuum Transmitter
New!
Differential from
Atmosphere range for Load lock and backfill applications!
The Model 22 is a full-featured Linear vacuum transmitter
which is only slightly larger than a conventional vacuum gauge tube. It
includes a precision interchangeable vacuum gauge tube and all of the
circuitry necessary to:
excite the tube,
amplify its signal,
linearize it, and
provide zero and span adjustments
EEPROM storage of the adjustments
RS-232 output
Linear voltage Output
Model 22's are typically used to drive recorders and to provide
process inputs to PLC's and other process instrumentation.
The
Model 22W
(wide range) has all of the features of the Model 22, and reads the full
range of pressures from Atmosphere to 1 millitorr.
It also has control outputs.
The
Model 22wLCD
has all of the features of the 22w and adds a backlit LCD character
display. The display has 24 characters, 12 in each of two lines.
The
Model 22T
uses an absolute pressure transducer, and has all of the features of the
22w combined with outstanding accuracy (+/- 1/2 %) over the range of 0
to 760 torr. It is often used for backfilling applications.
The
Model 22Td
uses an differential-from-atmosphere pressure transducer, and has all of
the features of the 22w combined with outstanding accuracy (+/- 1/2 %)
over the range of 0 to 29.9 inches of mercury or comparable torr and
millibar ranges. It is often used for Load Lock applications.
