SECTION 1 SYSTEM DES CRIPTION

TRANSMISSOMETER /RETRO REFLECTOR

The OPM4001 is a precision, double-pass, dual beam Transmissometer that consists of a transceiver (transmitter/receiver) mounted
on one side of a stack or duct and a passive reflector mounted on the opposite side. The light source, photo detectors, and all
measurement/reference optics used in opacity measurement are housed in the transceiver.

NORMAL MODE OF OPERATION

The Dual beam measurement system has a stack mounted Transmissometer sensor system consists of an optical transceiver
mounted on one side of the stack and a retro reflector mounted on the other. To avoid errors due to ambient light, the wide band

lamp

(See Drawing) is electronically modulated and projects a collimated beam of light, which is split into a reference beam, and a

measurement beam by an optical

Beam splitter

. The reference beam is directed to the reference detector,

RD.

The measurement

beam is projected across the stack to a

Retro

reflector

that returns the beam back across the

stack to a beam splitter and directs the
measurement beam to the measurement
detector,

MD

. A portion of the returning light is

also  sent  to  the  TTL  (Thru  the  Lens)  bulls-eye
target viewed through a window provided at the
rear  of  the  Transmissometer.  The  bulls-eye  is
used  to  correct  changes  in  alignment  and  is
unique in that no moving parts are used!

The ratio of the measurement and reference

detectors  is used  to  provide  Transmittance  2  (T
2) signal. Because the same light source is used
for  both  detectors,  and  a  Measurement  /
Reference  ratio  is  used  throughout  for  the
calculations,  the  monitor  is  insensitive  to
variations

in

light

intensity.

Since

all

measurements are made on a ratio basis, all
resulting computations are independent of the absolute intensity of the light source or contamination of the optics associated with

the collection and focusing of the energy from the lamp. The (T 2) signal is converted to a current format and sent to the control unit
for processing. At the control unit the signal is processed to read 0-100% Opacity, provide alarms and outputs.
