PROCESS INSTRUMENTS

nnnn

TM2000 TRACE OXYGEN ANALYZER

nnnn

Quickly responds to process change.

nnnn

KEY BENEFITS

nnnn

II RS-485 serial communications,

nnnn

0 - 20/4 - 20 mA current outputs,

nnnn

and digital alarms for systems

nnnn

integration.

nnnn

II Save money on calibration gases

nnnn

by calibrating with percent gases,

nnnn

and then reading accurately in

nnnn

low ppm ranges.

nnnn

II Modular design for easy

nnnn

upgrades and field service.

nnnn

II User-friendly, menu driven

nnnn

software that includes helpful

nnnn

system status text messages

nnnn

allows you to begin using the

nnnn

TM2000 quickly. Advanced

nnnn

software diagnostics and on-line

nnnn

help further simplify the use of

nnnn

the TM2000.

nnnn

II The zirconium oxide sensor

nnnn

will not fail to a zero oxygen

nnnn

reading, as with other sensor

nnnn

technologies. Therefore, your

nnnn

process is always protected.

nnnn

II Optional sample bypass

nnnn

improves response times and

nnnn

keeps sensor inlet purged of

nnnn

dead volume.

nnnn

OPERATION

nnnn

The TM2000 net oxygen

nnnn

analyzer protects industrial

nnnn

processes by quickly responding

nnnn

to changes using an industry-

nnnn

proven zirconium oxide sensor.

nnnn

It operates within a wide range

nnnn

of 0.1 ppm to

nnnn

100% oxygen, and

nnnn

can accurately

nnnn

respond from

nnnn

atmosphere to low

nnnn

ppm oxygen levels

nnnn

in just seconds.

nnnn

In addition, the

nnnn

TM2000 can detect

nnnn

excess combustibles

nnnn

process upsets in

nnnn

the presence of very

nnnn

low ppm oxygen readings.

nnnn

This unique benefit is particularly

nnnn

important in cryogenic gas

nnnn

generating processes, where the

nnnn

TM2000 can distinguish between

nnnn

an oxygen upset condition and

nnnn

an excess combustibles upset

nnnn

condition.

nnnn

The TM2000 is supported

nnnn

by the Series 2000 Controller,

nnnn

which comes complete with a

nnnn

standard weatherproof housing.

nnnn

The controller can be housed

nnnn

separately from the sensor.
