INTRODUCTION
I ndumart TTH108 Series of Temperature
Transmitters provide accurate and reproducible
conversion of RTD or thermocouple signals to 4-20
mA output.
One model is designed to accept RTD input. The
others accept types J, K, E, L, N and T thermocou-
ple inputs and also provide automatic thermocouple
cold junction compensation.
The transmitters will be supplied in standard factory
calibrated ranges, but on board links allow the
transmitter to be easily re-ranged to operate over
most industrial and commercial applications. ZERO
and SPAN potentiometers are provided to allow fine
re-calibration at both ends of the scale.
The TTH108 Series are mounted on the standard
33 mm fixing centers of miniature RTD or thermo-
couple connection heads. Optionally, the transmit-
ter maybe ordered as DIN rail mounting or secured
in an IP65 rated box.
