TX93A and TX94A Series are discontinued. As an upgrade substitute, please check out the new TXUN temperature transmitter for details.

OMEGA™ ultra-miniature temperature transmitters convert millivolt inputs from thermocouples or resistance from RTDs into 4 to 20 mA outputs. Transmitters are available in color-coded enclosures covering the four most popular thermocouple types (J, K, T, and E) as well as three-wire 100 Ω platinum RTDs. Featuring state-of-the-art integrated circuits and electronic design, these ultra-compact transmitters have a diameter of only 35.6 mm (1.40") and are designed to fit inside many compact thermowell protection heads, such as the OMEGA™ NB2. Omega also provides complete thermocouple and RTD assemblies.
TX93A and TX94A transmitters can eliminate long runs of costly field wiring in a variety of applications. A stable 4 to 20 mA output signal is produced proportional to the transmitter’s specific input type and calibrated temperature range (see Range Code table, right). Adjustability of ±25% for zero and span is provided to facilitate some rangeability. The transmitted signal eliminates noise pickup, voltage drops, and multiple cold junction errors, and it requires only a twisted pair of copper wires for loop connections. All models and ranges of these ultra-miniature transmitters are available with fully epoxy-potted electronics (specify “-P” option), which give ultimate protection in extreme environments.
