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 & 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.
