Temperature Measurement 4-20mA Transmitter
4
The
XTR105
is a next-generation 4-20mA transmitter specifically
designed for signal conditioning and linearizing 100
RTDs
(Resistance Temperature Detectors). It’s also great for current-
excited bridge sensors.
This easy-to-use one-chip solution includes on–board sensor
excitation (dual 800μA current sources), instrumentation amplifier
and 4-20mA current-loop output.
This new generation device also includes a regulated 5.1V supply,
powered from the 4-20mA loop, that can be used to power external
circuitry.
Bridge Transducer 4-20mA Transmitter
The
XTR106
is a next-generation 4-20mA transmitter designed for
signal conditioning and linearizing bridge sensors that measure
pressure, weight, and strain.
The device is a one-chip solution that includes on–board bridge
excitation circuitry (voltage excitation), instrumentation amplifier, and
420mA current loop output.
The XTR106 has a regulated 5.1V supply, powered from the 4-20mA
loop, that can be used for external circuitry.
High Impedance RTD 4-20mA Transmitter
The
XTR112
and
XTR114
are next-generation 4-20mA transmitters
designed for signal conditioning and linearizing high impedance (up
to 10k
) RTDs and bridge sensors.
The device is a one-chip solution that includes on-board circuitry
for exciting the RTD or bridge (XTR112—dual 250μA, XTR114—
dual 100μA current sources), amplifying the RTD signal, and
transmitting the signal over a standard 4-20mA loop.
Each has a regulated 5.1V supply, powered from the 4-20mA loop,
that can be used for external circuitry.
4-20mA Transmitters
NEW!
Compared to other 4-20mA devices, the XTR105, XTR106 XTR112 and XTR114 offer more functionality,
better loop compliance voltage, lower cost and a smaller package.
