Introduction
The TX93 two-wire transmitter receives and measures signals from thermo-
couples and sends an output current of 4-20 mA which is directly proportional
to the thermocouple millivolt input. It is designed to connect with only two cop-
per wire leads that will supply the voltage to operate the transmitter from a
power supply, and also carry the output current. The output current is used for
recording, computing, or controlling.
If the TX93 is mounted inside a protection head, (see Figure 3-1), the thermo-
couple extension wires are replaced by two copper wires that carry the 4-20 mA
signal and dc voltage to operate the transmitter.
