Stack Interface Equipment and Accessories
Extractive Sampling Equipment
| The objective of the Acid Rain Program (Part 75) is to ensure
accurate accounting of pollutant emissions from affected utility
boilers and turbines using Continuous Emissions Monitoring
Systems (CEMS). These monitors are required to meet strict
performance standards to demonstrate their measurement accuracy.
One measure of the accuracy of a CEMS is the Relative Accuracy
Test Audit, or RATA. The RATA requires three runs with three
traverse points per run. Designed to meet the requirements
of US EPA Guideline Document 031 for Multi-Point Probes, the
Apex Instruments PS2 RATA Sampler (RS-PS2-SYS) enables
simultaneous, continuous sampling of the three traverse points
without having to move the probe.

The RATA Console (RS-CM-20)
is used to monitor the differential pressure across each orifice
of the RATA manifold to ensure equal flowrates. This features
a single Magnehelic® pressure gauge with switch activated
solenoids to monitor the three differential pressures. Temperature
controllers for the RATA probe and oven are included. Includes
vacuum gauge to monitor system pressure.

The Heated Filter Tri-Probe
(RSO-50-18) is compact and versatile allowing efficient
RATA sampling. This includes several unique products that
are specifically designed by Apex Instruments. These include:
6-port combination manifold and filter unit for equal flowrate,
mixing and filtration of the sample; heated oven with slip-off
cover for easy service access; and multi-point probe with
2 inch oversheath that can support the unit using optional
packing glands.

Features:
• 6-Port Combination Manifold and Filter Unit
• Heated Filter Compartment with Slip-off Cover
• Multi-point Heated Probe with 2 inch Oversheath
• Three 0.050 inch orifices (~15 lpm @ 10" H2O
Pressure Drop)
• Three 3/8 inch Tube Fittings Allow Easy Addition
of Probe Extensions

|
| Note: The Heated
Filter Tri-Probe is easily fitted with different probe extensions
to meet the specifications of the test site. Select traverse
points that ensure acquisition of representative samples over
the stack or duct cross-section. For particulate laden sources
a sintered pre-filter is recommended to prevent the plugging
of the orifice. |
|
The RATA Sampler U-Cord (U-PS2-o)
connects the Heated Filter Tri-Probe to the Rata Console for
remote monitoring of sampling conditions.
|
Features:
• Four 1/4 inch Urethane Pressure Lines with Quick Connects
• Power Cable with 4-Pin Circular Connection
• Two Type K Thermocouple Lines with Connectors
• Low-Friction Woven Braid Cover |

Cable Entry Seal (CES-S4S)
The Cable Entry Seal securely attaches to our standard
HSRL Sample Lines with an adhesive lined heat-shrink tubing.
The seal serves as an excellent strain relief and seals
out cool air. Alternative strain relief are available. Call
for details.
