Monitoring and maintaining process variables at the appropriate levels is extremely critical in
industrial automation and process control. A sensor in the industrial environment is either
continuously or periodically measuring vital parameters such as temperature, pressure, flow,
etc. The primary challenge of sensing in industrial environments is conditioning low signal
levels in the presence of high noise and high surge voltage.
This warrants for extremely low noise, low drift, precision programmable gain amplifiers
and instrumentation amplifiers with an appropriate common-mode voltage. The rate of change
of the measured signal is usually not very rapid and hence high-resolution precision delta-
sigma converters are widely used in industrial sensors. Low power consumption is another key
requirement for industrial sensors as many of them are powered off the traditional 4–20 mA
loop. Digital connectivity features such as PROFIBUS, IO-Link, and wireless connectivity are
increasing in popularity as they provide continuous monitoring, fault diagnostics and reduce
start up times, greatly improving productivity and efficiency of the automation loop.
Texas Instruments (TI) has a broad portfolio of products catering to industrial sensing,
ranging from best-in-class precision amplifiers and data converters to interface products,
power products and high-performance microprocessors. TI’s cutting-edge semiconductor
manufacturing processes provide industrial designers with products that meet the highest
standards and that are optimized for industrial environments and extended product life cycles.

Temperature sensors are used to measure temp-
erature and have a wide range of uses in industrial
and commercial applications. Temperature
measurements are commonly made by using a
resistance temperature detector (RTD), thermistor or
thermocouple.
RTDs have wire winding or thin-film serpentine
elements that exhibit changes in resistance with
changes in temperature. Thermistors, typically
made of ceramic or polymer material, also exhibit
significant changes in resistance with changes
in temperature. Thermocouples consist of two
dissimilar metal wires welded together to form
two junctions. Temperature differences between
the junctions cause a thermoelectric potential (i.e.,
a voltage) between the two wires. Holding the
reference junction at a known temperature and
measuring this voltage permits the temperature
of the sensing junction to be deduced. A constant
and linear excitation source is a critical aspect
of RTD/thermistor sensing, while cold junction
compensation is the key to a good temperature
measurement with thermocouples.
With its high integration, excellent resolution and
accuracy, the ADS1248 offers a single-chip solution
to all of these types of temperature measurements.
The ADS1118 is a lower-cost solution whichhas the basic core needed for any temperature
measurement and an extremely accurate on-chip
temperature sensor that is perfect for accurate cold
junction compensation.
The LMP90100 family consists of highly
integrated, multi-channel, low power Sensor AFEs.
A true continuous background calibration feature
allows calibration at all gains and output data rates
without interrupting the signal path. The background
calibration feature essentially eliminates gain and
offset errors across temperature and time, providing
measurement accuracy without sacrificing speed
and power consumption. Continuous backgroundsensor diagnostics, allow the detection of open and
short circuit conditions and out-of-range signals,
without requiring user intervention, resulting in
enhanced system reliability.

Pressure sensors convert a physical value –weight, tire pressure, level, force or flow – into a
differential signal in the range of millivolts per volt
and use metal thick-film, ceramic thin-film, or
piezoresistive technologies, to name a few. The
majority of designers use the cost-effective
piezosensors that can sense 25 mbar to 25 bar.
However, these sensors are very nonlinear and
temperature-dependent and have a large offset
and large offset drift. They also require attention
to electronic calibration and compensation.
Features and Benefits
• Bridge excitation and sensor signal
conditioning
• Sensor error compensation: span, offset
and temperature drifts
• Sensor linearization circuitry
• Digital calibration via one- or two-wire
serial interface
• Low, time-stable total adjusted error

Electronic weigh scales, which are found in many
industrial applications, use a load cell as the
primary transducer. Load-cell designs can bedistinguished according to the type of output
signal they generate – pneumatic, hydraulic or
electric. Strain-gauge load cells convert the load
acting on them into electrical signals in the range
of millivolts per volt. A major challenge in
designing weigh scales is that they must sample
multiple load cells while producing extremely low
input referred noise.
Another important factor is the analog circuitry’s
long-term stability with regard to offset drift and
gain. Here the accuracy of the amplified input
signal, either single-ended or differential, must
be guaranteed over years of operation. Hence
the signal chain has to handle the small signals
accurately in the presence of noise in additionto conditioning for offset, drift, temperature
dependency and other factors.
TI’s ADS1232 is designed as a highly integrated
delta-sigma ADC for low-level, high-precision
measurements, especially for weigh-scale
applications. The device consists of a low-drift,
low-noise instrumentation amplifier (selectablegain) and a high-order, chopper-stabilized
modulator followed by a digital filter in a
monolithic device. This is a single-chip solution
that can be directly interfaced as a front end to a
load-cell bridge output.
Features and Benefits • Complete front-end solution for weigh
scales
• Very low-noise PGA
• Only 17-nV input-referred noise with gain
of 128
• 23.5 effective bits with gain of 1
• Excellent 50-/60-Hz rejection:

The electromagnetic flowmeter consists of a
nonferromagnetic tube wrapped with a magnetic
coil. Electrodes in the tube’s inner isolated surface
are in contact with a conductive liquid that flows
through the tube. The coils around the pipe
generate a magnetic field within the tube. The
magnetic field inducts a voltage in the liquid that
is proportional to the speed of the liquid in the
tube. This voltage is measured via the electrodes.
Because the measured voltage is very low, precise
low-noise signal conditioning is required.
Coriolis flowmeter is a popular flowmeterthat directly measures mass flow rate. Applying a
strong magnetic field to a pipe through which fluid
is flowing makes the pipe oscillate at a particular
resonant frequency. When the fluid starts flowing
through the pipe, it is subject to Coriol is force.
The oscillatory motion of the pipe superimposes
on the linear motion of the fluid, exerting twisting
forces on the pipe. This twisting is due to Coriolis
acceleration acting in opposite directions on either
side of the pipe and to the fluid’s resistance to
the vertical motion. Sensor electrodes placed on
both the inlet and outlet sides pick up the phase
difference caused by this motion. This phase shift
due to the twisting forces is a direct measurement
of mass flow rate.
Low-noise instrumentation amplifiers followedby precision ADCs is typical of the signal-chain
path. Precision DACs or PWM drivers are used to
excite the field coils. Multiple-channel ADCs with
simultaneous sampling architectures make it
possible to take multiple measurements such as
temperature, phase, density, etc. at the same time
TI’s ADS1274, which is a 24-bit, 4-channel,
simultaneous-sampling delta-sigma converter
with up to 144 kSPS, is the perfect front end for
flowmeters requiring multiple measurements
(Coriolis). The ADS1259 is a high-linearity, low-drift, 24-bit, delta-sigma converter commonly used
in electromagnetic flowmeters.
Features and Benefits
• Multiple channels and simultaneous
sampling for measuring multiple process
variables at the same time
• Excellent AC and DC performance
• Selectable operating modes: High speed,
high resolution, low power

Power Management
Industrial field transmitters could be powered in
one of three ways: loop, line or battery.
Texas Instruments (TI) offers a complete line of
high-performance power management products
designed for industrial applications. The devices
shown are well-suited for powering sensors that
may require low noise and high efficiency in both
line- and loop-powered (4–20 mA) topologies. Many
TI DC/DC converters feature current-mode control
with fast dynamic response and a pulse skipping
eco-mode with low quiescent current which
saves energy at light loads. Battery-powered
transmitters can be designed using TI’s low-power
Buck and Buck-Boost converters.
Processor and Connectivity
The MSP430™ MCU, with its integrated analog
peripherals, is the perfect platform for designers
looking to implement calibration routines,
compensation algorithms, etc. The computing
power and rich peripherals set accented by ultra-
low power consumption, makes the MSP430
MCU the universal choice for sensor design.
For flowmeter applications which require more
signal processing than offered by a standard MCU,
the C5000™ platform of DSPs is the optimal
solution. The C5000 DSP has an FFT accelerator
core that enables computing FFTs in a matter
of seconds while drawing very little current. The
ultra-low-power architecture of the C5000 DSP
offers superior signal-processing power while still
being able to be powered off the 4–20-mA loop.
Traditional analog (4–20 mA) interface remains
the popular choice for industrial control and
sensor applications. The other popular protocols
include HART, PROFIBUS and IO-Link . TI’s IO-Link
interface products have integrated regulators
and diagnostic outputs. In addition, wireless
options based on IEEE 802.15.4 protocols are
becoming more prevalent. TI is committed to
provide solutions for both traditional and emerging
industrial interfaces.
