GDS-78XP Process Gas Monitor

The GDS-78XP Process Gas Monitor is designed to provide monitoring for gas sample streams compatible with standard electrochemical, infrared or photoionization sensors. For gases that require electrochemical sensors, the stream must contain at least 20% oxygen. If the target gas can be detected by an infrared or photoionization detector, then the gas stream is not required to contain oxygen. The GDS-78XP combines the industry-proven reliability and performance of GDS Corp GASMAX gas monitors with high quality sample conditioning and flow measurement components to deliver cost-effective solutions for process monitoring applications.

GASMAX Gas Monitor

The heart of the GDS-78XP is a GASMAX gas monitor configured for sample flow monitoring. The popular GASMAX family includes monitors that are loop-powered, DC-powered or wireless 900Mhz or 2.4 Ghz. Wireless units can be battery powered when used with toxic gas sensors, or DC powered for use with infrared, catalytic bead or PID sensors.

A magnetic switch menu-driven operator interface eliminates all analog potentiometers and allows setup and calibration without hazardous area declassification. When used with DC- powered systems, electrochemical sensors include temperature compensation and local heater for increased accuracy in low temperature applications.

Flexible Sample Conditioning

The GDS-78XP includes a high quality stainless steel sample conditioning system, which includes a stainless steel inlet valve and high quality glass flowmeter. For high or variable pressure applications the GDS-78XP can be configured to include an adjustable regulator and stainless steel coalescing filter or combination coalescing and membrane filter with sample bypass loop. Inlet pressure can vary between 1.0 psig and 3000 psig, depending on sample conditioning option selected.

Designed for XP Environments

GASMAX monitors are certified for use in Class I Div 1, Groups B, C & D areas when monitoring non-reactive gases. When measuring reactive gases such as chlorine or chlorine dioxide, a loop-powered GASMAX / EC must be specified and used with an intrinsically safe barrier for XP applications.

The GDS-78XP is available with optional NEMA 4x non-metallic and stainless steel enclosures.
