Installing The Dryer Or Oven Thermocouple; Shield Connections - Novatech 1635 User Manual

2.4

INSTALLING THE DRYER OR OVEN THERMOCOUPLE

Weld a 1/2 inch BSP mounting socket to the dryer or oven within about 300 mm, and upstream of the oxygen probe.
The thermocouple should be of similar length to the oxygen probe to prevent temperature distribution errors. The
thermocouple can be type 'K', 'T', or 'J'.
This thermocouple is optional. It is only necessary when it is required to read the moisture content in % relative
humidity. This is not possible in direct fired applications using an RGS-01.

SHIELD CONNECTIONS

All external wiring to the 1635 analyser should be shielded. Do not connect shields at the field end. Simply clip off
and insulate. An extra terminal strip may be required to connect all shields together. This should be supplied by the
installer.
