TELEDYNE ANALYTICAL INSTRUMENTS
The 3160 features six full-scale linear ranges of analysis:
• 0–1 PPM
• 0–10 PPM
• 0–100 PPM
• 0–1000 PPM
• 0–1%
• 0–25%
An AutoRanging feature automatically selects the range that is appropriate for a
given reading. For example, if the O
2
level exceeds 100% of the current range, the
analyzer switches to the next higher range. When desired, a manual override feature
allows a particular range of interest to be locked-in.
With the AutoSpan feature, the analyzer automatically calibrates at scheduled
intervals, and automatically performs electronic zeroing and sensor settling detection
during calibration.
Five user-programmable absolute-reading (PPM) alarm setpoints with assignable
Form 1C (SPDT) relays are provided, along with a RS-232C bidirectional serial data
port, and four signal outputs for chart recorders, etc. The
RS-232 serial port can be used with or without a modem to connect with
• a personal computer loaded with the Teledyne Remote Analytical
Control Software (TRACS)
• any terminal or terminal emulation software
• a custom computer program
Several analyzer functions, including troubleshooting, can be run from your PC
through the phone line to the analyzer.
The analyzer has separate sample and span gas ports, which allow the installation
of an external source of span gas for calibration without interfering with the sample
gas line.
An optional scrubber installed into the sample system allows sample gas to be
used as a zero gas after treatment with the scrubber. If the scrubber is installed, pneu-
matic valves on either side of the scrubber open automatically during zeroing.
Note: Units equipped with a scrubber should only be used with inert gases
and saturated hydrocarbons.
The analyzer output is not affected by minor changes in the flow rate. Analyzer
performance is stable under minor mechanical vibration.
