Technical Information of Charge Ampliﬁer● Theory of Operation
The charge ampliﬁer converts the charge output from a piezoelectric accelerometer(vibration sensor) into a voltage signal and ampliﬁes it.
Since the current is obtained by diﬀerentiating the electrical charge with respect to time (I = dQ/dt), the charge ampliﬁer issuitable for conditioning a minute signal like the current ampliﬁer (I/V converter). Let Vout, Qs, Cs be the output voltage, output
charge from the accelerometer, accelerometer capacitance respectively, then, the simple equivalent circuit model amongcharge and voltage gives the following equation.

The cutoﬀ frequency FH of a high-pass ﬁlter can be deﬁned

・RL

Since the resistance RL controls the low frequency response of the circuit, it shall be generally large. For this reason, an
integration circuit using an operational ampliﬁer is absolutely essential so that electric capacitance connected to theaccelerometer does not have an inﬂuence on the charge sensitivity. The parallel connection of the accelerometer and cablecapacitance, diﬀerence in electric capacitance between accelerometers and electric properties of cable such as material,
structure, length worsen precision in the measurement.

In order to ensure reliable performance of the charge ampliﬁer the user must be familiar with the type and characteristics of an accelerometer for use with it and select the most suitable accelerometer for the application. Two types of accelerometer are available,“piezoelectric accelerometer”and“accelerometer with built-in electronics”.
※ As for the details of accelerometer, see“Application Note for Accelerometer”at pages 9 and10. Since the charge ampliﬁer isprecision equipment, please pay attention to the following points.
● Since a dirty connector or cable may have a bad eﬀect on measurement accuracy, please clean them.
● Please take care of handling the connector so that static electricity will not apply to it because there may be a possibility of being failure or damaged.
● It is impossible to disconnect the accelerometer with built-in electronics under the condition that the power is supplied through the charge ampliﬁer.
● In measuring the velocity and displacement please set the cutoﬀ frequency of the high-pass ﬁlter to 3 Hz to remove the ﬂuctuation of meter
indication in the low frequency range. The indicated value will become stable.
● Please check the sensitivity, measuring range, and settings of the ﬁlter before commencing the measurement.
● Please use the accelerometer whose mass is 1/50 of a measuring object. If the accelerometer is heavy, there is a possibility of changing
its dynamical characteristics. Depending on the conﬁguration its vibration level may reach 100 times of excitation level due to resonance.
As such is the case, please select the suitable accelerometer whose shock limit meets the requirement for your application. If failed to
select a proper accelerometer, the accelerometer may be damaged or charge ampliﬁer failure.

Application Note for Accelerometer● Introduction
Accelerometer
The accelerometer is used for measuring acceleration of an object. Gravity, vibration/motion, and shock can be measured as threeprominent types of kinematic measurable amount. The positional change of the mass caused by acceleration and low acceleration
can be measured with some accelerometers; therefore, static acceleration (response at 0 Hz) and gravity can be detected. Other
type of accelerometer has high frequency characteristics enabling to measure vibrations up to 20 kHz. They are generally referred
to as acceleration pickup, acceleration sensor, and accelerometer.

Accelerometer Type … The commonly used accelerometers are described as below.
1 Piezoelectric Type Accelerometer
The accelerometer having a piezoelectric element generates the charge being proportional to the acceleration to which theaccelerometer is subjected. The output charge will be converted into the voltage output with the charge ampliﬁer to measureacceleration. The output charge is very low in the order of picocoulomb, thereby being electrostatically aﬀected by bending or
twisting of a cable giving a false output signal. For this reason, the low noise cable is essentially used.
Features of Piezoelectric Accelerometer● High sensitivity・Small
to high acceleration)● Broadband (measurable from low to high frequency)● High mechanical strength

accelerometer with built-in electronics● Large measuring range (from very weak vibration● Superior environment immunity● Power supply is unnecessary except for● Wide temperature range (extreme cold, high temperature)

2 Accelerometer with Built-in Electronics
It says the piezoelectric accelerometer which has a built-in charge to voltage converter.

Features of Piezoelectric Accelerometer with Built-in Electronics● High sensitivity despite small size because of built-in charge to voltage converter● Other types of instrument cable than low noise cable are acceptablesmall● Built-in ﬁlter deﬁnes any frequency response● Sensitivity deterioration and noise due to cable length are● Immune to humidity because of low impedance

In order to measure vibrations accurately please mount the accelerometer with enough care. When it is not mounted and ﬁxed
properly, its high frequency response and dynamic range will be limited not to provide reliable measurement of vibrations. In
mounting and ﬁxing the accelerometer the mounting stiﬀness between accelerometer and vibrating body shall be increased.

◆ Fastening with Bolt
The mounting method with the bolt is the best solution. If thismethod is acceptable to your application, we recommend it to
all the applications. The mounting surface shall be ﬂattened

then, please securely fasten the accelerometer with the bolt.

Mounting Surface

Mounting Surface＜Mounting with Bolt ①＞
If the accelerometer is the center stud

with the ﬁxing bolt.

＜Mounting with Bolt ②＞
If the accelerometer has a tappedhole at its bottom, please provide atapped hole in the mounting surface
to ﬁx it with the ﬁxing bolt.

If the mounting surface is not quite smooth, the highfrequency response may be improved by applying a thin layerof silicon grease to the surface.

◆ Sticking Accelerometer with Adhesive Cement
If drilling a tapped hole for directly mounting the accelerometer to vibrating
body is not available, we recommend ﬁxing with an epoxy-based or

If the accelerometer is a center stud mounting type, it can bemounted after provided a tapped hole in the mounting surface byelectrically insulating it with the dedicated insulated mounting stud.

◆ Electrical Insulation
The accelerometer shall be isolated from a measuring object when the noise comes to be mixed in due to the diﬀerence in electric potential between
measuring object and instrument or due to ground loop formed by direct mounting of the accelerometer. To mount the accelerometer by isolating fromthe measuring object the insulated mounting stud (option) or screw/washer shall be employed. Joining with an adhesive through ceramic or epoxy
insulator is also acceptable. Direct mounting method using an adhesive may break down the electric insulation due to thickness of bonding layer orsurrounding moisture. In trying to isolate and mount the accelerometer, please use the dedicated insulated mounting stud or joint it through theinsulator.

◆ Fixing with Wax
When the same accelerometer should be used at many measuring points, wax makes it easier to attach and remove that. Its operating temperature
range, however, should be limited to lower than 40℃ or app. because the stiﬀness of wax decreases at higher temperature. It is limited to the application
using a light accelerometer or measuring relative low acceleration.

◆ Mounting with Magnet Holder
If the mounting surface of the measuring object is ferromagnetic material, the accelerometer can be mounted with a magnet holder. Its mounting
stiﬀness depends on the condition of the mounting surface, total mass of the accelerometer and magnet holder, and magnetic force.

＜Connection Treatment of Low-noise Cable＞
When accelerometer cable bends or becomes deformed mechanically, the noise signal due to static electricity is generated
because the output impedance of the piezoelectric accelerometer is very high. When the coaxial cable is mechanicallyFigure 1shieldcore

insulator

distorted or twisted, small separations between the shield and insulator layer will occur as shown in Figure-1 and a-known as the so-called triboelectric eﬀect. To reduce this eﬀect as much as possible the surface of an insulator in a special

capacitor will be formed locally. This part becomes electrically charged through friction. If the charge ampliﬁer receives this+low-noise cable is processed with a conductive ﬁlm (carbon layer). As this is the case, the capacitor cannot be formed in
the low-noise cable even if the insulator moves away from the shield conductor to drastically reduce the charge due to thetriboelectric eﬀect. The low-noise cable is most widely used with piezoelectric accelerometers. Commonly used instrument
coaxial cables are not suitable for this application. Even if the low-noise cable is used, it shall be clamped as ﬁrmly as
possible to the vibrating specimen so that it may not be subjected to any mechanical force or may not whip. The accelerometer with built-in electronics does not always have to use the low-noise cable because its output impedance is low.

＜Instructions on Handling Accelerometers＞
In particular, if failed to follow the ground rules in the below, the accelerometer would be failure or damaged. Please handle it with enough care.
※Do not use it beyond its operating temperature range. ※Do not use the general-purpose accelerometer in water, oil, and other liquid. However, a waterproof type is also available. Pleasecontact us. ※When it is dropped or struck it will be subjected to higher acceleration than its shock limit. Take extra care not so as to apply the excessive shock force to it. ※Firmly ﬁx theaccelerometer not so as to be loosened. And tighten the connector not so as to be loosened. ※Do not apply the acceleration of more than its rated vibration limit. Even low acceleration whose
frequency is close to the resonance frequency of the accelerometer may cause it to be failure or damaged. Take extra care. ※Take care not to intrude moisture, oil content, adhesive, solvent
into the inside of a connector. ※Clamp the cable to the measuring object because it may generate noise or break when excessive force or vibration is applied to the cable. ※The sensitive axisof the accelerometer is uniaxial except for triaxial type. And the mounting or joining surface of the accelerometer cannot be changed, therefore, mount it to take the sensitive direction. ※When
the accelerometer is mounted using an alpha-cyanoacrylate (instant) adhesive, use a solvent such as acetone solution or special depleting agent to disconnect it. ※Do not use theaccelerometer with built-in electronics beyond its rated voltage range. ※Contact us or our representative in advance if your application shall be performed in unusual environments.

12700 Series Piezoelectric Type Accelerometers
The piezoelectric accelerometer is used in combination with the charge ampliﬁer. The 700
Series Accelerometers employ the shear mode construction for the piezoelectric sensing
element, the shear mode which provides a stable output against environments of rapid temperature change. This stable characteristic is suitable for a wide range of application, in particular, for measuring the vibration mode of small and lightweight material, and low accelerationof a building.
