The TX69 is a digital, PC
programmable, galvanic isolated
two-wire smart transmitter, that
converts 13 types of thermocouple
sensors; 12 types of RTD sensors,
configured as 2, 3 and 4 wires;
potentiometer, resistor and millivolt
inputs, single or differential–into
process current loop.
A 31⁄2 digit LED display is integrated
forming a transmitter field monitor
unit which is visible in dark
installations. A 24 bit A/D converter
is the heart of the outstanding
performance. The light intensity
varies as a function of the current
loop, which serves as the light
energy source.
The transmitter can be set and
wired to perform differential
measurement conversions of
temperature sensors as well as
mV sources.
The output current is temperature
linearized and can be set to be 4 to
20/20 to 4 mA–or any range within
these limits. The current is limited to
3.6 and 22 mA. The TX69 samples
and updates the output current in a
rate of 2 to 4 samples per second
depending on the sensor type.
It is fully configurable in
dry-configuration mode by which
the connection to PC is performed
with no voltage needed, and the
configuration parameters are stored
in a non-volatile memory.
Exceptional digital accuracy of
typical ±0.1°C is provided for most
sensors regardless of the calibrated
span. Extremely accurate coldjunction temperature measurement
provides precise
compensation
throughout the entire
ambient range.
Detection of sensor
breakage or disconnection
of input leads, forces the
output to a pre-defined up/
down scale value. The unit
continuously monitors the sensor
and automatically returns to normal
operation mode when the sensor is
recovered.
The TX69 is housed in a Aluminum
enclosure, and the front panel has
a special red filter for optimal view.
