Cabinet may not include all of the following components
The electronics support cabinet provides an air distribution system, power management, and
communication necessary to support EXACTUS temperature measurement. Typical cabinets may
accommodate one to eight EXACTUS units.
A. Pyrometer – Measures intensity of light from the optics and calculates temperature. For Fiber-
Optic Instruments, fiber-optic cables thread into the nosepiece of the electronics module providing
the light for the measurement. Typical cabinets may be equipped with one to eight units
(channels).
B. Analog Output Module – Provides DC signal output of the temperature measurement. There are
separate pairs of labeled screw terminals for the 4-20mA and 0-10V output.
C. Cooling Fan – if used. Active air cooling from the air purge system is the preferred method of
cooling the cabinet as it reduces the risk of introducing contaminants to the cabinet.
D. Digital Interface Module (located beneath analog output module) – Supplies power to the optic
head and analog output module. Passes on data to the analog output modules, the multi-channel
interface box, or a PC via serial connection.
E. Power Supply – Converts 120/240 VAC to 24 VDC
F. Multi-Channel Interface Module – Allows for PC communication with all instruments via Ethernet
connection.
G. Gland Nut for Power Input
H. Gland Nut for Signal Cables
I.
Optional Cabinet Cooling Air Inlet Valve
J. Conduit containing the combined power/data cable and the air purge flow.
K. Liquid Separator (may be integrated with air pressure regulator).
L. Air Pressure Regulator with Pressure Gauge.
M. Cables
a. Fiber-Optic Version: Fiber-Optic Transmission Cable
b. Integrated System: Combined Power/Data Cable
