High-Accuracy Inclinometer with MachineLearning Core
The IIS2ICLX from STMicroelectronics Geneva, Switzerland)
is a high-accuracy, low-power, 2-axis digital inclinometer for
use in applications such as industrial automation and structural-health monitoring. It features a programmable machine-learning core and 16 independent programmable finite state machines that help edge devices save power and reduce
data transfers to the cloud.
Using MEMS accelerometer technology, the IIS2ICLX inclinometer has a selectable full
scale of ±0.5/±1/±2/±3g and provides outputs over an I2C or SPI digital interface.
Embedded compensation maintains stability over temperature to within 0.075 mg/°C,
ensuring high accuracy and repeatability even when ambient temperatures undergo
extreme fluctuations. Its ultra-low noise density of 15 g/Hz enables high-resolution tilt
sensing as well as sensing of low-level, low-frequency vibration, as required in structuralhealth monitoring.
Since it is a 2-axis accelerometer, it can sense tilt with respect to a horizontal plane along
two axes (pitch and roll) or, by combining the two axes, can measure the tilt with high and
repeatable accuracy and resolution with respect to a single direction of the horizontal plane
over a range of ±180°.

Spring-Loaded LVDTs for Surface
Measurement
NewTek (Pennsauken, NJ) spring-Loaded LVDTs are
used for surface measurement of paper, rubber, paneling
and other materials as part of quality control processes in
sawmill, wood processing, paneling, rubber, and automotive production plants. They are outfitted with precision wheels and other accessories for
active monitoring of materials along a line or conveyor. Data collected from the gaging
probes enables operators to monitor a product profile for abnormalities or an out-of-tolerance specs.
They feature a stainless-steel probe assembly and hermetically sealed construction that
enables operations in harsh industrial conditions such as exposure to water, sawdust, flying
chunks of wood, and other debris. The gage heads are rated 65°F to 185°F, with linearity of
±0.15% of full range.
They provide reliable output for over one million cycles with near-zero drift. Available
in measurement ranges of ± 0.04 to ± 2 inches, the gage heads are available in a variety of
custom options including right-angle connectors, temperature ranges up to 400°F (200°C),
mild radiation resistance to 30 MRad and pneumatic probes.

Electromagnetic
Flowmeters - Accurate
Readings in a SpaceSaving Design
The KOBOLD Instruments, Inc.
(Pittsburgh, PA) MIM magneticinductive flowmeters work without
moving parts, unlike rotating vane flow meters.
With extensive options for on-site programming, they are suitable for a wide variety of applications, particularly for batching. Configurable
optical buttons can be used to display parameters such as flow rates or temperatures. A
changing color system in the display warns of
limit violations. Since it is produced in a remote
version, the flow meter can be used for media
temperatures from -40°F up to +284°F.
The MIM, incorporates an IO-Link to meet
Industry 4.0 requirements. It can be set up in
just a few steps in the program menu with hot
key buttons. The rugged and flexible design
enables simple and easy installation, even in
tight-fitting pipe systems.

Non-Contact Industrial Pyrometer
The new thermoMETER CTRatio pyrometer from Micro-Epsilon
(Raleigh, NC) provides accurate results with non-contact temperature measurements in harsh industrial environments. Unlike conventional pyrometers, it delivers constant measurement results
even when surrounded by dust, smoke, and vapors, as well as with
contaminated lenses, or when the object is moving within the
measuring field.
It is based on the ratio measuring principle, which enables reliable measurements in
harsh metal processing environments. Even if only 5% of the measurement object is within
the measurement spot, the CTRatio provides reliable measurement results. Due to the high
spectral sensitivity in the range from 1.45 to 1.75 m, measurements are possible from +250
°C. New calibration methods extend the temperature measuring range to +3000 °C. With a
response time of just 1 ms, even high-speed processes can be monitored reliably.
A green sighting laser that works at a wavelength of 520 nm helps alignment of the
pyrometer and offers significantly better visibility on red-hot glowing, metallic surfaces.
