The Model 750 Opacity Monitor
|
|
| is a precision dual beam Transmissometer with
Solid-State electronic modulated source to provides continuous, low
maintenance, precision measurement of opacity, smoke and optical
density in industrial applications. It is a cost-effective instrument
that serves as an aid in operating pollution and/or process control
equipment. |

A High performance Dust/Opacity Monitoring
System with Single-Pass Transmissometer
The sensor system consists of an optical
transmitter mounted on one side of the stack and a detector mounted on
the other. The light source is electronically modulated making it
insensitive to ambient light effect and projects a collimated beam of
light. The 4-20mA output range is 0-100% Opacity and can be connected
to a number of devices to control or display the opacity.

Swing Away Sensor
Cleaning the optic windows are a breeze. Both
sensor have alignment pins to assure no change in alignment after the
sensor have been open for cleaning. Large heavy duty latches make for a
air and water tight seal. Clean purge air can be connected to the inlet
of the mounting flange provided to keep the windows clean for long
periods of time.

Applications
Pipe duct of stacks from 1 to 46 inches can be
measured. Typical uses are for bag houses, exhaust fan control, ideal
for meeting Title V opacity (smoke) regulations soon to be enacted,
oven exhaust, diesel test stand exhaust, duct fire alarm, multi-point
systems and more.
