8. Absolute pressure transducer.
1.3.1 Probe enclosure
The dilution probe and conditioning assembly is housed in a fiberglass enclosure that
measures approximately 24 inches (H), by 24 inches (W), by 9.75 inches (D). The enclosure
is designed to protect the instruments and electrical controls from highly corrosive
atmospheres.
1.3.2 Enclosure heater
The enclosure heater is located on the bottom, right-hand side of the enclosure (please refer
to the 7000 series probe box assembly drawing, item 17). The assembly consists of one 400-
watt heat element, a 30 CFM fan, and an adjustable thermostat switch. The fan motor runs
continuously when power is supplied to the probe conditioning enclosure heater. The heat
element cycles on and off according to the temperature inside the enclosure. The temperature
of the enclosure is maintained at 100°F by the adjustable thermostat.
