INTRODUCTION
The SEM1500/TC Rail-mounted Isolating
Thermocouple Transmitter provides accurate and
reproducible conversion of most thermocouple
inputs to industry standard 4-20 mA output. The
unit can also accept strain gauge input or any
millivolt input between-5 and+50 mV. Automatic
cold junction compensation is provided to be used
with thermocouples or fixed zero compensation
may be selected for mV or differential
thermocouple measurement.
The small size of the unit enables many units to be
fitted in a small space, and a high packing density
to be achieved. The output signal is galvanically
isolated from the thermocouple by 500 volts DC to
remove the effect of earth loop or earth leakage.
The versatility of this temperature transmitter
results in lower stock holdings and greater
operational flexibility. The transmitter can easily
be configured in the field for any range from
-100°Cto+1600°C.
