Description and Principle of Operation
APPLICATION
The Universal Analyzers Model 270SF Extractive Gas Sample Probe Assembly is designed to be installed on sample
stacks containing non hazardous gases. The 270 may be installed in an unclassied location. Filter changes can be made
in less than one minute.
The 270SF lter will mount by means of a pipe ange to a mating ange on the stack. The size of the ange can be
specied by the user and can include 2”, 3”, 4”, 6” or DIN type. A 1/2” NPT female threaded connection is provided for the
sample probe to mount inside the mounting ange. Stack temperatures and corrosive gases will determine the material
and design of the probe to be used.
Sample ow rates of up to 20 liters per minute can be extracted and ltered through the Model 270 with a minimal amount
of pressure drop.
GENERAL DESCRIPTION, HEATED FILTER SECTION
The Model 270SF is a Extractive Gas Sample Probe Assembly consisting of the lter body mounted in a NEMA 4X
Fiberglass Enclosure or Stainless Steel Enclosure. An optional blowback system is provided to allow the blowback to
occur on command from a computer, data logger, PLC, UAI timer card or external switch mounted in a safe area.
Two 63 watt heaters are mounted in an aluminum sleeve around the lter cavity. The heater holds the temperature of the
lter at 340°F (171°C). A hermetically sealed bi-metallic thermal switch mounted to the lter body keeps the temperature
from exceeding 350°F (177°C) by opening the circuit at that temperature. An optional independent temperature sensor
can be provided as a means to measure and transmit or record the temperature of the lter. A second thermal switch, set
at 225°F (107°C) is provided to be used as an alarm contact, if the temperature drops below the switch temperature. In
colder climates, an additional heater can be supplied for the enclosure. This heater will maintain 150°F (65°C) inside the
enclosure.
Several types of lter elements can be supplied with the Model 270. The 2 µm ceramic lter is supplied as an economical
general purpose lter. A similar ceramic lter with an internal 0.1 µm coating is available for ner ltration or to provide a
surface to enhance the blowback capability where the particulates have a tendency to ll the pores of the 2 µm element.
A 2 µm, 316SS Filter can be inserted for those applications where the ceramic lter is determined to be unsuitable.
Additional ltration materials and pore sizes are available on request.
Blowback air is used to clean the lter element. Compressed air supplied to the blowback assembly needs to be clean
and dry (-40°F/°C recommended). Instrument quality air is preferred. The pressure should be as high as possible, up to
125 psig (8.8 barg). High pressure air lls the accumulator (a 7” (178mm) diameter SS sphere) and provides a substantial
blast when the high ow solenoid valve opens. This loosens the particles on the lter surface and forces them back
through the sample probe into the sample point. The period of time between blowback cycles should be set to occur
before the pressure drop across the lter begins to increase beyond acceptable limits. By installing and monitoring a
vacuum gauge ahead of the sample pump, a maintenance interval can be established. This can be as often as every
fteen minutes but no less frequently than once per day. The time period between blowback cycles can be based on a
calculation to estimate the amount of sample required to deposit from three to ve grams of solids in the lter element.
Instrument air usage is minimal and smoothed by the fact that the air accumulator is charged over a period of time through
a 1/4” instrument air line. The recharge time could be extended with a restriction in the air line if it were desired to reduce
the pressure pulses on the instrument air supply and to consume instrument air more slowly.
The calibration gas is injected into the chamber ahead of the lter. This is close to the sample source, as is required by
many EPA ofcers. A back pressure check valve (set at 3 psig (0.2 barg) is provided in the cal gas injection path to insure
that calibration gas does not leak into the sample while the sample is being drawn through the lter.

Installation
The probe tube (stinger) should be screwed into the 1/2” NPT tting on the inside of the mounting ange. To prevent
galling, coat the threads with an anti-seize compound. Remove and anti-seize compound from the inner wall of the probe
tube before attaching it to the probe. The length of the probe should be selected to extend into the center third of the
stack; or if the stack diameter is greater than 12’, at least 6’ into that stack. The studs on the mounting ange should be
joined to the sampling nozzle on the stack and the assembly bolted into place.
A heated sample line should be supported close to the Model 270. The heated sample line should be fed through the heat
shrink boot on the bottom of the enlcosure. Connect the sample tube to the center tubing tting (3/8”) on the lter. The
unheated portion of the sample line should be kept short and insulated to avoid condensation. Connect the calibration
gas line to 1/4” tubing tting located on the left side of the chamber and is connected to the chamber via a check valve. If
the compressed air line is part of the heated sample line, it can be connected to the 1/4” tting adjacent to the blowback
accumulator. If an external air line is to be used for blowback, bring the air into the enclosure through a bulkhead tting
(supplied by others) to be installed in the wall of the enclosure, typically the mounting location is in the bottom of the
enclosure, and connect the air to the same 1/4” tting.
Provide power to the terminal block(s) within the stack lter enclosure in the Model 270. 150 watts (without heated
enclosure) or 350 watts with heated enclosure, at 115/230VAC is required.
NOTE: The supply power circuit MUST include an overprotection device with a maximum rating of
20A. A disconnect switch must be located in close proximity to the probe.
A thermal switch mounted in the aluminum heater will control the temperature to 340°F (171°C). Insure the
power supplied to the heater matches the heater voltage requirement shown on the serial number tag. The
voltage requirement can be changed by changing the jumpers on the terminal strips (reference terminal strip
label or drawings for details). An independent ground wire should be run to the grounding terminal on
the terminal strip.
If an independent measurement and display of the oven temperature is desired, a temperature sensor can be slipped into
a 1/8” diameter thermowell supplied on the heater tube assembly.
The nal installation step is to insure that the sample line is insulated completely. Close the cover of the enclosure and
secure the latches. After securing the heated sample line, use a heat gun to shrink the entry boot onto the sample line.
The goal is to keep the temperature of the gas sample at a temperature above the dew point of the gas all the way from
the stack to the sample cooler/dehydrator.
