Series 907 Analog Convection Transducer
Instruction Manual - #109070001
Connect the Transducer to the vacuum system flange using the appropriate gasket and mounting
hardware.
Orient the Transducer to prevent condensation of process vapors on the internal surfaces through
line-of-sight access to its interior. Use a screen or porous filter at the port if necessary (see Section
6.12, Accessories).
For an NW16KF or NW25KF flange:
The NW##KF style flange requires a self-centering O-ring between mating flanges. Use a metal
clamp and tighten the clamp to compress the mating flanges together. Do Not use a plastic clamp.
See the Grounding Requirements.
Attach the Transducer to the mating NW-style connector on the vacuum chamber. Use a new seal
and the appropriate tools to tighten the metal clamp.
4.3 Electrical Connections
Connect a user-supplied cable to the Transducer using a mating 9-pin D-sub connector with strain
reliefs to ensure proper electrical connection and to reduce stress on the connectors.
Connect the cable to the Transducer and to the Controller before turning ON the system. Tighten
the thumb screw on top of the cable to make sure it is securely in place.
4.3.1 Input/Output Wiring
Connect a user-supplied cable to the 907 Transducer using a mating 9-pin or 15-pin D-sub
connector with strain reliefs to ensure proper electrical connection and to reduce stress on the
connectors. Table 4-1identifies the pins the pinout of the D-sub connectors.
Notice
A solid electrical connection between the sensor tube and the grounded
vacuum system must be used to shield the electronics from external power
sources.
Do not use a compression mount/quick connect fitting for
positive pressure applications.
Do not connect or disconnect any electrical connectors while
power is applied to the equipment (hot swapping). Doing so
may cause damage to the equipment or severe electrical shock
to personnel. This hazard is not unique to this product.
