on the TX62 and TX63

The TX62, TX63, TX64
programmable transmitters
provide an isolated 4 to 20 mA
signal linearized to temperature
or process input. The TX62 &
TX63 smart transmitters provide
the same functions as the TX64
with the additional feature of
smart communications. Smart
communications lets one calibrate,
reconfigure or check status right at
the transmitter via the TX60-HH or
from a remote location with the
TX60-RS232. The TX60-HH is a
battery operated handheld terminal
that connects to the output of the
transmitter anywhere along the pair
of loop wires. The TX60-RS232
connects the same way and
provides a 25-pin RS232 connection
for use with a remote PC.

The TX62 “Smart” transmitter
provides unmatched accuracy of
any 2-wire transmitter in its class.
OMEGA®guarantees NIST­traceable calibration for a full 2
years. “Smart Communication” lets
you calibrate, reconfigure or check
status right at the transmitter or from
a remote location up to 1524 m (5000') away.

The TX63 extends “Smart” technology to signal
conditioners. The same power that digital processing
brought to “Smart” transmitters is available now for
signal conditioning. The TX63 accepts a variety of
inputs: volts, millivolts, milliamps, potentiometers, and
resistance. The TX63 can linearize almost any input.
Square, square root and logarithmic functions are easily
selected. For more difficult linearization tasks, a 21-point
custom linearization curve can be entered by the user.

The TX64 combines the best features of conventional
analog transmitters with the advances of digital
technology. The result is a programmable 2-wire
temperature transmitter that sets new standards of
performance. The TX64 is the ideal replacement for
conventional temperature transmitters. The high
performance, low initial cost and substantially reduced
maintenance means a significant overall cost savings for
your process. The TX64 is extremely easy to use and
does not require a handheld terminal.
