Analyzer monitors concentrations of hydrocarbon gas.

Press Release Summary:



Process-control gas analyzer, carrying full FM and CSA approvals, is designed to monitor methane, propane, butane, ethanol, or any of 70 hydrocarbon gases. It taps into gas-flow manifold or pipe for continuing in-stream and on-stream sampling. Readout can be fed to upstream control valves for automatic correction of process parameters. Any change in gas concentration is detected immediately by IR sensors in analyzer.



Original Press Release:


Process-Control Analyzer "Sees" Hydrocarbon Gases


A new process-control analyzer that can monitor ultra-high
concentrations of virtually any hydrocarbon gas has been in-
troduced by Sensor Electronics of Minneapolis.

Carrying full FM and CSA approvals, this new gas analyzer is
designed for use in industrial process-control systems as well
as laboratories, test setups, preproduction runs - or wherever
precise monitoring of methane, propane, butane, ethanol or any
of some 70 hydrocarbon gases is needed.

The analyzer simply taps into the gas-flow manifold or pipe
for continuing in-stream and on-stream sampling. Readout can
be fed to upstream control valves for automatic correction of
process parameters; it can also go to computers, recorders and
alarm systems.

Any change in gas concentration is immediately detected by IR sensors in the analyzer; resulting milliampere deflections reflect even minuscule variations.

Built-in circuits automatically compensate for aging compo-
nents and changing ambients. And because this new analyzer
uses simple optics - no complex mirrors or complicated beam-
splitters - it shrugs off high gas concentrations, low oxygen
levels, high and low pressure extremes.
