1.1 General Description

The OMEGA®TX93 Thermocouple Two-Wire Temperature Transmitter

accepts thermocouple sensor types J, K, T, or E and will produce a standard

4-20 mA output signal proportional to that produced by its attached input

temperature sensor. Transmission of the proportional current output may be

accomplished by using inexpensive copper wire.
