The TX401 and TX402 head mount temperature
transmitters transform a temperature signal acquired
from a Pt100, Pt1000 (TX401 only) or Ni100 RTD
sensor or from a thermocouple (TX402 only) into a
linearized 2-wire loop-powered 4 to 20 mA output.
The characteristics of these converters ensure high
precision on the reading scale with 16-bit conversion.
The 4 to 20 mA output can be scaled based on the
desired temperature input range.
The programming procedure uses an RFID (NFC)
mode with the dedicated TX400-RFID programmer that
allows the user to make all calibrations and settings
quickly and without the need to power and connect
up the transmitter. Simply connect the TX400-RFID
programmer to the USB port of your PC, start the
RF Programmer configuration software and place the
transmitter on top of the TX400-RFID programmer to
establish communications.

TX402 shown larger than actual size.
These temperature transmitters are also provided
with a data logging function for the input signal.
Transmitters have a non-volatile memory (circular
buffer) for data-logging with user-selectable sampling
time. The user selects the sampling time (1 to 3600
seconds) and then each time the 4 to 20 mA loop
powers the device, the input value is stored to nonvolatile memory.
Using the TX400-RFID programmer along with the
RF Programmer configuration software (software is
a free download from OMEGA) the user can:
•
Completely configure the transmitter including
scaling the 4 to 20 mA output to desired temperature
input range
• Implement field calibration to compensate for gain
and offset errors
•
Download logged data to PC for visualization and
printing
