Twisted-Pair and Shielded Cables
For remote-sensor distances greater than 8 inches, or
in particularly noisy environments, use a twisted pair. A
practical length is 6 to 12 feet. For longer distances, the
best solution is a shielded twisted pair such as that
used for audio microphones. For example, the Belden
8451 works well for distances up to 100 feet in a noisy
environment. Connect the shield to SHO.
Cable resistances affect remote-sensor accuracy; 1&
series resistance introduces +0.004癈 error.
Remote Diode Shielding
Temperature measurements will reflect significant error
if a portion of the bias current supplied to the diode
anode is allowed to flow through parallel paths to
ground. If the diode-connected transistor is mounted
on a PC board, suppress error-producing leakage
current by surrounding the collector/base leads with a
metal trace that is connected to the SHO shield output
(Figure 8).
