Design Description

The CiSCO sample probe is designed to mount on a 4 inch 150 pound ANSI flange. It can be fabricated out of any machinable material (typical materials include stainless steel, aluminum, etc). The probe is available in its standard model, a high temperature configuration and an explosion proof model. The probe assembly includes a heated filter chamber located outside the flange in a NEMA 4 enclosure. This chamber and enclosure allows for the filter to be periodically maintained safely without removing the probe from the gas stream, eliminating filter clogging due to the direct impact of particulate or water droplets. The heater prevents the sample temperature from cooling so it inhibits condensation of the sample gas moisture.

Filter easily cleaned or replaced

The application-specific filter is rated at 5 to 25 microns and can be easily replaced or cleaned. The filter is safely accessed via a hinged assembly, secured with two captive screws. Separate gas connections for sample extraction and backflush are incorporated into the filter chamber design. The calibration gas is injected on the stack side of the filter.

Simple maintenance

The insertion tube, which penetrates the stack, is easily maintained. If an obstruction occurs, the straight through design of the tube allows the blockage to be cleared with a ramrod without removing the probe from the gas stream.

Utilities not required at probe location

No active components are located at the sample probe. Plant utilities are not required at the sample probe location. The CiSCO sample probe is completely supported from the analysis enclosure (all necessary utilities, air, etc are supplied by the system).

Meets regulatory requirements

CiSCO’s sample probe is specially designed to meet federal and local environmental regulatory agency requirements for continuous emission monitoring systems (CEMS).
