The GDS Corp. Pipeline Stream Monitor (PSM) is designed to continuously monitor an incoming gas sample for hydrogen sulfide, carbon dioxide, combustibles and / or other toxic gases. Output options include 4-20mA current loop, multiple alarm-level-based relay contact closures, RS-485 MODBUS® interface or wireless modem.
Designed for use in hazardous areas, the PSA integrates state-of-the-art GDS Corp sensors and transmitters with custom-designed gas flow control and conditioning subsystems.
Incoming gas is filtered and regulated. If necessary, a flow of ambient air / oxygen is mixed with the incoming sample to ensure long sensor life and accurate readings. Air flow can be provided externally or provided by the PSA (see photo).
If local display is required, a GASMAX II powered gas monitor (shown with H2S and CO2 sensors) or GASMAX / EC two-wire gas monitor can provide single or dual-channel inputs for electrochemical or bridge sensors. If no local display is required, a GDS-49 sensor transmitter can be used for cost-sensitive applications.
Fully customized versions of the PSA are available. Please contact GDS Corp for more information.
