variable, the probe should be close to the work area.

Some experimenting with probe location is often

needed to find its optimum position.

In a bath process, the addition of a stirrer will help

to eliminate thermal lags. Since the thermocouple

basically a point measuring device, putting more than

one thermocouple in parallel will provide an average

temperature reading and produce better results In air

heated processes.

NOTE:

if controls

with

“F”

"S”

outputs

drive loads

with grounded or hot input terminals (not floating), an

isolated

thermocouple must be used. Otherwise, when

both

input

and

output

are grounded, severe ground loop

currents will

result,

causing errors and permanent

controller damage.

Standard thermocouple limits of error are

± 4ºF

0.75%

(half that for special) plus drift caused by

improper protection or over temperature. This is far

greater than controller error, but can not be corrected

at the sensor except by selection and replacement. In

extreme case, total system requirements can be met by

offsetting the control to compensate for these outside

errors.
