than actual size.

The TX86 is a 2-wire loop-powered,
galvanic-Isolated, programmable
universal input temperature
transmitter that is designed to
be head-mounted, but can be
standalone as well. It uses 16 bits
A/D and D/A converters offering high
accuracy with Linearized 4 to 20 mA
or 20 to 4 mA outputs. Being a
user-friendly rugged instrument, it
displays the measured variable and
has a SSR output.

The TX86 has 3 push buttons on its
front keyboard and a 4-digit
7-segment bright LED display
module that indicates the values of
the measured parameters during the
Measuring Mode while also
providing prompting and
programming instructions during the
setup and calibration mode routines.

The 1000V AC galvanic isolation
removes all ground loop effects.
Three different engineering units
(°C, °F and %), can be displayed
and the chosen unit is highlighted
by an associated LED lamp when in
the measuring mode.
