New Products
9 DoF Inertial Measurement Unit
Silicon Sensing Systems Ltd (Plymouth,
UK) is launching a new 9 degrees of freedom
(DoF) inertial measurement unit
(IMU) that extends the performance of its
predecessor, the DMU30, while delivering a
reduction in volume, weight, and power consumption. At 50 × 50 × 50
mm, and weighing 200 g, the DMU41 represents a 54% reduction in
volume and a 42% reduction in weight over the DMU30. In addition,
it has a power consumption 50% lower than DMU30's typical usage.
DMU41 is an all-silicon MEMS IMU, which combines excellent
angle random walk and bias stability with exceptional low noise characteristics.
The unit contains three inductive and three piezoelectric
resonating ring gyroscopes with six capacitive accelerometers, along
with 3 magnetometers. Data can be provided at variable output rates
up to 2kHz. Outputs can combine angular rate, acceleration, delta
angle, and delta velocity, temperature, and built-in test results.

High-Precision, Low-Profile
Medical Sensors
TDK Corporation (Tokyo, Japan) presents a
new range of highly accurate differential pressure
sensors (part number B58621V), designed
as printed circuit boards. The sensors are designed for measurement
ranges of 16 mbar full-scale (FS), 100 mbar FS and 7 bar FS, with absolute
accuracy of up to ±1 percent FS at temperatures from -20 ºC to +70 ºC.
Their footprint of 24 mm × 26 mm accommodates pressure ports
and inlets (allowing for simple screw fitting and easy maintenance) as
well as two plug connectors for easy implementation of daisy chain systems.
The integrated SPI (Serial Peripheral Interface) enables easy integration
into various digital applications. The sensors are EN ISO 13485certified
for use in medical devices. Precise pressure loss measurements
in the flow lines allow flow rates to be accurately calculated in ventilator
equipment, and they are particularly well suited for mobile ventilators
due to their extremely low profile of only 6 mm. The sensors are also
suitable for monitoring filters and gas admixtures.

Signal Conditioner for Digital or
Analog Communications
The NewTek Sensor Solutions (Penn-sauken,
NJ) NTC-6000 Qwik-Calo
Graphene-based Hall Effect Sensor
for Mapping of Battery Cells
The graphene GHS01AT Hall Effect sensor
from Paragraf (Cambridge, UK) is optimized
for use in relatively low field environments and
normal ambient temperatures. It brings magnetic
field measurement resolution towards that of more complex
magnetic sensors; yet with the small size and ease of use of a Hall sensor,
it can address monitoring tasks for which conventional technologies
cannot provide an effective solution.
It will be of value in battery cell analysis when investigating the validity
of different battery cell chemistry derivatives and form factors
under development. It can provide detailed real-time current density
(local cell internal resistance) mapping - with any variations at different
locations in the cell being detected during repeated charge/discharge
cycles. If hotspots arise, the local mapping of internal cell resistance
in these areas could provide insights into the physical processes
occurring in the lead-up to their formation.

Transportation Data Logger With
GPS, Shock, and Climate
Recording
Saelig Company, Inc. (Fairport, NY) has
introduced the MSR 175plus Data Logger,
which contains two 3-axis-acceleration sensors (±15 g/±200 g), a temperature
sensor (-20 to +65 ºC), a humidity sensor (0 to 100% rel.
humidity), air pressure sensing (0 to 2000 mbar), and an ambient light
sensor (0 to 65,000 lux). The tamper-proof data logger records potentially
damaging shock events as well as the associated ambient conditions
with the exact geographical position via its GPS/GNSS receiver.
The two 3-axis-acceleration sensors measure at a rate of up to 6400
times per second. In addition, the robust mini data logger measures
and stores temperature curves, humidity, air pressure, and light. It will
store 2 million data values and even with active GPS tracking, the
removable, rechargeable 2400 mAh LiPo-battery enables recording for
up to 8 weeks, and at least one year without GPS tracking.

LVDT Signal
Conditioner completes the measurement system
for AC-operated LVDTs by providing the excitation and digital output
required by many of today's laboratory, industrial automation, and process
control applications. Without internal electronics, AC-LVDTs can operate
in extreme environments but require the NTC-6000 Signal Conditioner to
convert position feedback into readable output for use by computers,
PLCs, data acquisition systems, and data loggers.
The conditioner offers a variety of selectable excitation frequencies,
analog output types (0 - 10V, 0 - 5V, 0.5 - 4.5V, +5V, +10V, 4 - 20mA) as well
as digital communications to a host computer via an RS-485 output. The RS485
port also supports the hot swapability of sensors by saving set-up parameters,
and automatic excitation synchronization for multiple unit systems.
Features include front panel null indicators and pushbuttons to set
zero and full-scale output positions along with automatic excitation
synchronization for multiple unit systems.

Cov
In-Vehicle Prototyping System
dSPACE (Wixom, MI) offers its
MicroAutoBox III in-vehicle prototyping system
with a high number of channels and an
extended range of bus and network interfaces.
With the addition of the new DS1521 I/O board variant, the system
is particularly suitable for communication-intensive developments
that take into account the centralization of the E/E architecture,
among other things.
Typical applications include intelligent gateways, running supervisory
controllers to control other ECUs in real time via buses and networks,
and designing central control units with service-based Ethernet
communication. To ideally address these applications, the DS1521 Bus
and Network Board provides eight CAN FD channels, three automotive
Ethernet ports (100/1000BASE-T1), two FlexRay connectors (A/B),
three LIN channels, and additional UART, digital, and analog interfaces.
For particularly communication-intensive applications, the
MicroAutoBox III can also be equipped with two DS1521 boards, which
results in doubling the number of interfaces.
