Figure 3-2 : Basic SENTRY 1510 Installation
Connecting the Furnace Exhaust to the SENTRY 1510 Intake
The SENTRY 1510 is provided with 32 mm threaded flange fitting, like the
SENTRY 1500. This fitting is now provided in the bottom half of the controller.
Use a mating female threaded fitting to make the connection to the furnace
exhaust. A short length of quartz tubing is used from the process tube to the
exhaust line. This quartz transistion piece may have a reduced I.D., depending on
the furnace manufacturer. The quartz I.D. should be no more than 10MM. If a
smaller line is used, the pressure differential across it may prevent the SENTRY
from controlling the pressure in the chamber.
Note: The inlet and outlet of the SENTRY 1510 are offset by ½” forward
from the SENTRY 1500.
Connecting the Facility Exhaust to the SENTRY
The facility exhaust connection to the SENTRY 1510 is made with a 63 mm
threaded flange fitting. This fitting is offset down from the SENTRY 1510 input by
the same distance as the SENTRY 1500. Use a mating female threaded fitting to
make the connection to house exhaust. Facility exhaust requirements are detailed
in section 1, page 4.
