Pony® Sample Conditioning System

The Pony® Sample Conditioning System (PSCS®) is ideal for sampling wet or dry natural gas when a compact solution mounted directly to the sampling probe is preferred. The PSCS contains a self-limiting block heater, Watlow® PID temperature controller, system temperature limiter, and a single or multistage pressure regulator, all mounted inside a Pony® Heated Probe Enclosure. The close coupled system reduces the opportunity for richer gases to condense within sample tubing and protects analyzers from damage by solids or liquids while delivering a representative sample. The Pony® Sample Conditioning System is the only probe mounted sample conditioning system that can be powered by the heat trace tube bundle, creating a cost effective solution for new or existing locations.
