PCB Piezotronics introduces new smaller triax mems sensor for
road load data acquisition applications
PCB Piezotronics,
a world leader in vibration, acoustic, pressure, force and torque
sensors, has introduced a new triaxial Micro Electro Mechanical
Systems (MEMS) sensor for use in road load data (RLD) applications
that is significantly smaller than the previous generation device.
The new series 3713B accelerometer measures just 20.3mm cubed
and offers DC response for measuring low frequency vibration
and motion over full scale ranges from ±2 to ±200g.
At 62% smaller and 78% lighter than the previous model, the new
3713B is ideal for use in road load tests to measure the transient
and steady state inputs of a vehicle as it traverses a road surface
in the anticipated region of use or a replicated drive profile
on a test track. Road load measurements take into account all
projected vehicle and driving parameters such as mass, inertia,
air and rolling resistance, road characteristics, engine load
and vehicle speed.
The new series 3713B accelerometer features gas-damped silicon
MEMS sensing elements for uniform, repeatable performance with
protection against high frequency overload. Electrically, the
sensor offers a single-ended or differential output signal with
power, signal and ground leads for each channel. Supply voltage
regulation permits operation from +6 to +30V DC and the low-noise,
low-impedance output signal may be transmitted over long cables
without degradation.
The new series 3713B triaxial MEMS accelerometer complements
PCB Piezotronics' wide range of sensors for use in RLD applications
including single- and three-axis force sensors, wheel force transducers
and conventional ICP® accelerometers, alongside strain sensors,
load cells and signal conditioners.
RLD is one of the best sources of fundamental information necessary
for analysis of the design, reliability and structural integrity
of vehicle components. The sensors must be accurate but, most
importantly, they must be robust and reliable to survive the
shock, heat, humidity and contamination associated with various
measurement locations on vehicles and the adverse conditions
of the road profile.
PCB Piezotronics sensors deliver reliable and accurate results
in these demanding environments, meeting and exceeding the requirements
of RLD acquisition applications.
All standard PCB sensors and products are supplied with a two-year
warranty and the company also offers to all customers, at no
charge, 24-hour emergency telephone support. This service makes
product and application support available to customers and end-users,
day or night, seven days per week.
