Triaxial accelerometers from PCB Piezotronics offer solutions
in wide range of vibration applications
PCB Piezotronics,
a world leader in vibration, acoustic, pressure, force and torque
sensors, offers a comprehensive range of triaxial accelerometers
to provide measurement solutions for a broad range of multi-axis
vibration applications. The company's extensive range of products
all offer high reliability and precision backed with the company's
guarantee of Total Customer Satisfaction (TCS) with many models
maintained in stock for quick delivery.
Model 356A45 is a new design of triaxial accelerometer, offering
frequency response of 10kHz on all three axes compared to competitive
products that typically offer upper frequency response from 5
to 8kHz but frequently have different responses on one of the
three axes. Model 356A45 accelerometers also feature 100mV/g
sensitivity with measurement range of ±50g pk and are
housed in a titanium package measuring just 10.2 x 10.2 x 10.2mm.
This model is also Transducer Electronics Data Sheet (TEDS) compliant.
PCB® also offers the non-TEDS model 356A24 with an even wider
frequency range of 12kHz on all three axes.
Even smaller than the above is the model HT356B01, a tiny 6mm
cube weighing just 1.0 grams. Offering sensitivity of 5mV/g and
measurement range of ±1000g pk over the frequency range
2 to 8000Hz (y or z axis) and 2 to 5000Hz (x axis), this ceramic
shear mode ICP® accelerometer is designed for use in high
temperature applications operating up to 180°C.
For applications where accelerometers are used in a fast changing
temperature environment such as under vehicles on track testing,
the effect of temperature change will affect the sensitivity
of the sensor. With standard triax models, the temperature coefficient
is around 0.14% per °C but PCB® also offers the 339A32
with a temperature coefficient of =0.02% per °C making it
very stable where transient temperatures are encountered.
Model 356B18 is an ultra-sensitive triax that is popular with
consultants for monitoring vibration in buildings and structures.
It features sensitivity of 1000mV/g so even a 0.2g vibration
would provide an output of 200mV. This unit can also resolve
signals down to 0.0005g.
For shock applications, PCB Piezotronics offers the model 350B50
based on a piezo crystal with ICP power. It features a measurement
range of 10,000g and can survive shocks of up to 25,000g. There
is also model 3503A1060KG, a triaxial MEMS shock accelerometer
featuring a 60,000g range on all three axes.
PCB Piezotronics' wide range of triaxial accelerometers is backed
by the company's guarantee of Total Customer Satisfaction (TCS)
and supported with a field-proven precision-engineered range
of mounting accessories including adhesive mounting bases, mounting
magnets, tools and triaxial mounting adaptors to ensure best
practice for a quality accelerometer installation and avoidance
of time consuming errors. Many of the most popular accelerometers
and accessories in the range are available from stock for delivery
within five working days.
