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.
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.
