High Temperature Displacement System
General Operating Procedures
Kaman Instrumentation high temperature, noncontacting displacement measuring
system is composed of three basic separate components that must be assembled into
and operational system. A diagram of the basic set of 8200 electronics required is
shown in figure 1. The components of the system are the signal conditioning
electronics (items 1,2,3), a low-temperature interconnecting cable (item 4), and
sensor (item 5, with integral metal sheathed high temperature cable),. Note that
active sensor coil is denoted by an 'A' and the inactive coil is denoted by a 'B'. In the
case of the 7200 or 8200 KDM1925 systems the active coil may connect to the sensor
marked 'B' (and the inactive to 'A') depending on the target configuration. It is easy
to tell if they are hooked up backwards because the output will not go more positive
as the target moves away from the sensor.
The sensor dimensions are shown in appendix C.
