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 3 1/2 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-configurationTM 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 Aluminum enclosure, and the
front panel has a special red filter
for optimal view.
