Gas Sampling Probes for Continuous Emission Monitoring and Stack Sampling

A gas sample extraction probe is designed for continuous extraction of gas from a process or exhaust stream. It is designed to be connected to a two-tube or three-tube heated Sample Umbilical and includes a strain relief grommet to secure the Umbilical. The basic probe includes an in-situ sintered metal filter which excludes particulate matter as the gas sample is withdrawn from the stream. A connection tee between the filter and the Umbilical tubes allows calibration gasses to be injected ahead of the sample line. The Umbilical, tee, and filter form a complete assembly that is fastened ttrough the mounting flange by a face sealing pipe union. The union can be opened for easy access to the filter as required for periodic inspection and maintenance. A variety of optional features are available according to application. Other configurations may include a heated, weather-proof enclosure, heated sample filter and back-purge capability.
