The
6400 Level System combines reliable digital signal and pulse counting
techniques with a specialized microprocessor. The result is a
level monitoring system with self-diagnostic features, so that
plant personnel can verify the operating status of each of many
level switches at a single, centralized indicator panel.
Thermo Electron has years of solid experience in supplying non-contacting
fly ash level measurement equipment to the specific needs of the
power generation industry. Innovative application of the technological
advancements made during the seventies has led directly to the
development of a system that now is becoming the industry standard
for the eighties: Thermo MeasureTech's 6400 Level System
It will display the actual
number of detector counts received from any designated hopper.
It will set all its own indicators, whether green, red, flashing
or off. It will test all its own internal counting circuit electronics
and indicate the status of each channel. And it will activate
its own common alarm light when needed.
The 6400 level system needs no
personnel inspection unit it signals an alarm condition. If process
problems occur, such as wall buildup or equipment failure, it
will identify and localize the problem. With the 6400, there also
is no need for preamplifier electronics at the detector. No need
to adjust a potentiometer since all adjustments are made digitally
on switches. No need for expensive overhead welding of mounting
hardware on the dual-beam source heads, nor for cutting hopper
lagging or welding in order to mount the detectors. No need to
worry about microprocessor loss of memory, should a power failure
occur, because of Thermo Electron's unique detector count comparison
system.
In short, the 6400 Level System
is a state-of-the-art, microprocessor system with the remarkable
ability to monitor as many as 64 fly ash hoppers, continuously,
economically and precisely.
