9.6.1 Sensor adapter
The sensor adapter is the part of the sensor that provides the internal connection feed-through
wiring from the internal sensor components to the socket module connections. The top of the
adapter has ten pins - four pins for the coils, four pins for the electrodes, and two pins for the
process reference. Each connection point has two pins associated for redundant continuity. See
Figure 9-2.
The best location for testing the sensor components is taking measurements directly on the
feed-through pins. Direct measurement on the pins eliminates the possibility of an erroneous
measurement caused by a bad socket module or remote wiring. The figure below shows the
feed-through pin connections as they relate to the terminal connections described in the tests.

9.6.2 Socket module
The socket module connects the sensor adapter to the transmitter. There are two versions of
the socket module - one for integral mount transmitters and one for remote mount
transmitters. The socket module is a replaceable component. If test measurements taken
through the socket module show a failure, remove the socket module and confirm
measurements directly on the feed-through pins of the sensor adapter. To remove the socket
module, refer to Section 8: Maintenance.
