The TX206TH is a cost effective
“smart” in head transmitter that
accepts thermistor temperature
sensors and converts sensor
output over a configured range to
a standard industrial (4 to 20) mA
transmission signal.
A variety of thermistor types
are available when using the
configuration software: select
thermistor type, temperature
range, units and burnout direction,
without requiring calibration
equipment.
PC configuration is performed
quickly using our new USB port
driven configurator by simply
connecting two clips to the
TX206TH loop terminals and
following the software instructions.
Calibration set-up may be saved
as a file on the PC for later use.
Alternatively, a single pushbutton
and LED indicator allows the user
to configure transmitter range
against a manually set input
condition. A red LED is included
to help guide the user. The LED
also operates as a sensor error
indicator.
Transmitters can be factory
configured for any range specified
at the time of order, removing the
need for user configuration. Extra
lead time is required.

Note: Comes complete with operator’s manual.
Note: To order with factory scaling use model number TX206TH-UKFS and advise thermistor type, range and output scaling required.
Ordering Example: (1) TX206TH Thermistor temperature transmitter, $215.00, plus (1) USB-CONFIG-TH ISB interface cable, $257.00, $215.00 + 257.00 = $472
