FuelCheck
®
Controller
Part No. FU-CT-*I (* represent number of channels up to 3, ie. FU-CT-1I)
The FuelCheck
®
Controller is engineered specifically to provide extremely stable, sensitive
and repeatable measurements for the
FuelCheck
®
Probes.
The Controller consists of 2 attached enclosures which can either be wall-mounted or installed in
a standard 19” instrument rack. FuelCheck
®
Controllers are available in 3 models to suit the
specific application; namely, 1 channel, 2 channel, and 3 channel. The 2 channel model (part#
FU-CT-2I) is shown in the manual.
The drawing below illustrates the principal components and layout of the Controller. The unit
should be installed in a location out of contact with direct sunlight to avoid drastic temperature
changes. The left enclosure is held at a constant temperatureso as to provide the required ther-
mal stability for the optoelectronic components.
If the enclosure is installed indoors in a climate-controlled environment, the 100°F (38°C) default
programmed temperature can be used. If the enclosure must be installed outdoors, it MUST be
mounted so that it will not be exposed to direct sunlight as constant temperature cannot be main-
tained if solar radiation is involved. If mounted outdoors, it is recommended that the temperature
controller be reprogrammed to approximately 20°F (11°C) above the maximum ambient tem-
perature. Please follow the directions in
Appendix C
for reprogramming the Omega CN132
Temperature Controller.
After powering up the Controller, approximately 1 hour is required for the temperature inside this
enclosure to stabilize; thus, do not open it as instability in the probe readings will result.
