Parker PGI’s Interceptor Series Gas Sampler is a compact, easy to use, install, and service composite sampling system that delivers accurate, high quality gas samples each and every collection period. The Interceptor provides a more cost effective sampling method when compared to on-line gas chromatographs and is far more accurate and comprehensive than traditional spot sampling. The highly reliable Interceptor is compatible with all flow computers, and is CSA Approved and Intrinsically Safe for Class I, Division 1, Groups C & D hazardous locations. In addition, it is offered with a wide variety of options including three specific pump styles with customizable features. All Interceptor materials conform to NACE (MR-01-75 latest revision).
The Interceptor consists of a positive displacement piston pump powered by a low pressure, gas operated, spring return piston actuator. Sampling is accomplished when a 3-way 6, 12, or 24 volt solenoid is energized allowing a downward pumping stroke of the piston actuator. This pump stroke captures a sample of the pipeline gas and stores it in the sample cylinder. The system can be set up to sample at a preset time interval (time based) or can be programmed to sample proportional to the flow rate of the process gas (flow based).
The Interceptor’s optional G6000 programmable controller allows for user controlled time-based or flow-based sampling. As a flow based sampler, the controller can take samples proportional to a flow rate provided by a flow meter or flow computer. The flow signal can be provided as 1 to 5 volts, 4-20 milliamps, or as a voltage pulse. Additional features include a configurable alarm output, ESD input for remote shut downs, three voltage trigger levels for pulse inputs and a programmable sample count limit.
