Acceleration
Transducers
Using a foil, sputter or semiconductor strain gage as the
sensing element, KYOWA acceleration transducers convert
the acceleration of a running vehicle or the vibration of a car
body or machinery into minute voltage to enable accurate
measurement of acceleration or vibration with a measuring
instrument. Each model is compact and lightweight, and
ensures superior static and dynamic characteristics.
Various rated capacities cover a wide scope of applications.
In addition, triaxial models are available for simultaneous
detection of accelerations in three directions: X, Y and Z.
• Compact and lightweight design results in minimal
effects on the vibration mode of the measuring object
to which the transducer is mounted.
• Wide frequency response range enables faithful detection of impact-initiated acceleration.
• Fatigue life is 10 million times or more.
• Triaxial models deliver minimal interference between
axes.
Strain gage
Installation and Removal
Temperature Effects
Install the acceleration transducer aligning the sensitive axis
with the acceleration measuring direction. The sensitive axis
(+←→ –) is labelled on the transducer. The polarity of transducer output is positive if the transducer is installed with the
“+” directed to the center of the earth (the gravitational acceleration).
To ensure flat frequency response characteristics, some models of acceleration transducers have oil sealed inside. The viscosity of the oil is adjusted to make the frequency response
flat at 23°C. Changes in viscosity due to temperature changes
affect the frequency response and phase characteristics.
Though a silicone oil of which the viscosity hardly changes is
adopted, the frequency response characteristics of the transducer are affected by temperatures as shown in the figure below. Thus, for accurate measurement in a frequency zone exceeding one-tenth the stated frequency response range, the
temperature of the transducer should be kept around 23°C.

Principle of Acceleration Transducers
102
As the basic configuration shows below, acceleration initiates
inertia force to the weight and deforms the leaf spring. The
strain gage adhered to the leaf spring detects the displacement of the leaf spring as a strain quantity proportional to the
acceleration. The strain gage signal is amplified to enable acceleration measurement. An advantageous feature of this configuration is to enable the transducer to respond to static
acceleration at DC.

Generally, the magnitude of acceleration is difficult to grasp
by human perception. If the transducer is dropped on the floor,
it may easily sense acceleration exceeding 9807 m/s2 (1000 G)
depending on the material of the floor. If a small-capacity acceleration transducer receives an acceleration 10 times larger
than the rated capacity, the initial voltage unbalance changes
outstandingly, thereby making the transducer unusable due to
disconnection of the gage, etc. Thus, the acceleration transducer must be handled carefully.

Depending on the model or application, the transducer is
mounted to the measuring object using CC-33A adhesive, bolts
or the mount base. For correct operation, mount the transducer according to the instruction manual. When removing,
take sufficient care not to damage the transducer by applying
excessive impact or force.
Acceleration output ratio vs. frequency differs depending on
mounting methods as follows:

Acceleration Transducers
AS-GA/AS-GB
Using a strain gage as the sensing element, AS-GA
and AS-GB series acceleration transducers are
designed to measure small levels of acceleration. The
miniature lightweight design makes them widely used
for measurement of vibrations in small structures or
scale models as well as in the field of human
engineering.
AS-GA models come with a hermetic terminal, and
AS-GB models, with the cable integrated. For both
series, convenient mount base options are available
to facilitate installation.
● Small and lightweight design results in
minimal impact on the vibration mode of
the object under measurement.
● Easy installation and removal using

Different from conventional strain gage acceleration
transducers, the ASQ series have a servomechanism
which ensures precise measurement of low levels of
vibration with high sensitivity. A dedicated signal
conditioner, the VAQ, is available for stable and reliable
acceleration measurement. ASQ transducers can be
used for measurement of vibrations generated by
running vehicles, earthquakes or wind in structures or
the ground as well as for measurement of general
vibrations occurring at low frequencies.
● Can measure acceleration in a frequency
range of DC to 100 Hz (DC to 300 Hz
available on request).
● Highly accurate measurement and high
rated output are ensured despite the
small, lightweight design.
● A pin to cancel 9.807 m/s2 (1 G) is provided.
● The ASQ-CA series transducers are
equipped with a connector for easy cable
connection and removal. The ASQ-CB

Principle of servo acceleration transducer
Label
Sensitive Transducer fixing part
axis
2-4.5 drilled hole
ø8, depth of counterbore 16
When acceleration is applied to the basic structure shown below,
the weight is displaced from the neutral position. The displacement
sensor detects the displacement quantity and sends via the
servoamplifier the signal to the drive coil which is fixed to the
weight support. When the signal current flows to the drive coil
placed in a magnetic field generated by the permanent magnet, the
electromagnetic force of the coil returns the weight to the original
position. Since the current is proportional to the applied acceleration, a proportional voltage to the acceleration is output from both
ends of the resistor inserted in the current loop.

Operational Precautions on ASM Series Transducers
Rubber cap
● Use the ASM series acceleration transducers with only an excitaton voltage of 2
VDC.
: Center of seismic mass
● Use screws to install these acceleration transducers. If installed using an adhe-
5.4
sive, they may receive an impact when removed, thereby causing damages.

● To fix these acceleration transducers to measuring objects, use the screws de-
9807 m/s2
scribed in the respective instruction manuals.
● When fixing these acceleration transducers with screws, slightly apply silicone oil
2–M1.6 round cross-recessed head machine screw
or grease to the contact surface. The transducers will closely be contacted with
and firmly fixed to the measuring objects.
*Export controlled products: Strategic commodities to which the Foreign Exchange and Foreign Trade Control Act applies. The necessary
legal procedures should therefore be taken with the Government of Japan if these products are to be taken abroad.
