3 Excitation/ Vibration/ Analog signal processing system NP/GK Series An accelerometer is a sensor that converts mechanical vibrations into electrical signals that are proportional to the vibratory acceleration. There are several different types of NP Series accelerometers available, such as an ultra-compact type that weighs a mere.2 g, a tri-axial type for simultaneous measurement of acceleration in the X, Y, Z directions, a waterproof type, a high-sensitive type. Select the type that best meets your application needs. These purpose-designed sensors are capable of high-sensitive detecting mechanical vibration. All the NP Series are Piezoelectric Accelerometers. Helpful Purchasing Guidelines How to choose a charge output accelerometer an accelerometer with built-in preamplifier Depending on the measurement application, the suitable sensor will be different. Refer to the guidelines below provided to help you make the correct choice; a charge output accelerometer or one with built-in preamplifier. Charge output accelerometer This type of accelerometer is used for the measurement of vibration from collision, drop, other similar impact vibrations, for vibration measurement at high temperatures. Charge output accelerometer Charge amplifier (converts charge output to voltage output) Accelerometer with built-in preamplifier This type of accelerometer is used for the measurement of general mechanical vibrations (diagnostic tests on plant equipment so forth). Accelerometer with built-in preamplifier A constant current is supplied Constant current supply amplifier Output of charge Voltage signal for voltage output. / BNC Voltage signal conversion adapter 1. The NP Series accelerometers are seismic* vibration detectors, therefore do not require a reference point for measurement. Measurement is performed simply by mounting the accelerometer to the measured object. 2. Compared to other vibration sensors, the NP Series accelerometers are compact lightweight, thereby facilitating mounting to a test object. Their small size makes them easy to hle.. The wide dynamic range enables the measurement of even ultrasmall acceleration levels. 4. The NP Series accelerometers are mechanically robust, are therefore ideal for measuring a large acceleration for measuring shock acceleration.. In general, the high resonance frequency the wide range of measurement frequency enable measurement with minimal distortion, even of waveforms containing wideb frequency components. 6. Various types of accelerometers with the performance capabilities are available to suit applications environmental conditions. k M C *: A vibration system where M is the mass, k is the spring constant, C is the viscosity resistance. Device NP-2 Series Amplifier High performance against external shock impact force. Can be used at high temperatures. Low-noise cable used. Care must be taken with fixing method of the cable (noise countermeasure). The cable length can be extended up to approx. m. Care must be taken, however, with countermeasure against noise interference. Sensitivity settings are required for each sensor. Care must be taken with the storage location (temperature, humidity, etc.). Comparatively expensive. Device NP-//7 Series Amplifier Drive current supplied to the sensor design, high sensitivity. Comparatively high noise-withst capability. Comparatively little affected by noise influence due to shaking of the cable or the like. The cable length can be extended up to approx. m. Extremely easy to hle. Ready to use as soon as the power is turned on., lightweight design. Piezoelectric Element Piezoelectric Elements Piezoelectric Accelerometers When force is applied to a single crystal or to barium titanate, an electric charge is generated on its surface. This is called the piezoelectric effect. Materials which exhibit the piezoelectric effect are called piezoelectric materials (piezoelectric elements). Piezoelectric Accelerometer A piezoelectric accelerometer is a sensor that utilizes a piezoelectric element as a seismic spring also as an electromechanical transducer at the same time. Electrical signals are output in direct proportion to the vibratory acceleration. Figure 1: Piezoelectric Accelerometer (a) Compressed type Robust against impact force Inertial mass () Piezoelectric element Base Post Piezoelectric element Inertial mass () Base (b) Minimally affected by pyroelectric noise base strain High sensitivity The influence on the frequency characteristics due to mounting methods There are several different methods of mounting the accelerometer on the measured object: screw mount, magnet base, adhesive, so forth. Depending on the mounting method selected, however, the frequency characteristics may be adversely affected. The figure below shows examples of the frequency characteristics for the various methods used to mount an accelerometer on the measured object.

Figure 1 shows the respective construction for each of the two types. With the compressed type (a), the piezoelectric element is swiched between the sensor base the inertial mass. With the shear type (b), the piezoelectric element is fixed in place between a post that is placed vertically on the base the inertial mass. The compressed type was conventionally used in the past, but recently the shear type, which is minimally affected by base strain sudden variations in temperature, has become more widespread. Force Force An electric charge is generated when either a compressing force or a pulling force is applied to the piezoelectric element in the axial direction. Force Force An electric charge is generated when force is applied to the piezoelectric element in the shear directions. What is mass effect? The mass effect is that the natural frequency of the object to be measured is influenced changed due to the mass of the sensor itself attached for measurement. Measured object m M fe=fe 1 - M M+m M: Mass of the measured object m: Mass of the sensor fe : Resonant frequency fe : Resonant frequency deviation Mass effect refers to the sensor mass ability to affect an object's natural frequency. Because natural frequency depends on mass, an object to which sensor is attached will have a lower natural frequency than that of the object itself. If a sensor mass is too large, the sensor will decrease the object s natural frequency, thus resulting in measurement error. It is recommended that the sensor mass is under one-fiftieth or hundredth of the object's mass. Note that mass is not the mass of the whole object but the mass of the part to which the sensor will be attached. The part may be unexpectedly light weight. 4

4 NP-2 Series Charge Output Accelerometers TEDS function What is TEDS? TEDS, an abbreviation for Transducer Electronic Data Sheet, is an information description format for sensor-specific information. TEDS facilitates your measurement process! TEDS is very helpful not only for the multi-channel, but also single-channel measurement. TEDS prevents occurring serious human error at the time of setup such as sensitivity setup. Ultra-compact lightweight NP-26 lightweight NP-21 high-temperature proof NP-27 general-purpose usage NP-29 NP-2 usage NP-212 Manufacturer ID : =ONO SOKKI Model number : 7N2 Serial number : 1246 Writable in USER area Measurement location ID: 21 Benefits of TEDS It reduces initial setting time of the sensor sensitivity by manual data entry. TEDS sensor features automatic setting which minimizes human errors such as miss-entry, giving sensor s information including sensitivity axial direction. As it is not required to manage data-sheet individually for each sensor, the work is simplified. Alternative solutions to make the existing sensor applicable to TEDS The NP-1N2 adapter makes an accelerometer with built-in preamplifier applicable to TEDS. You can use the existing sensor as TEDS applicable sensor only by adding sensor s information such as sensitivity to this adapter. TEDS function is available just by NP- series Accelerometer *The sensor is delivered after matching with NP-1N2 adapter. CE Marking What is CE marking? Sensitivity :.2 mv/ (m/s 2 ) Axial direction : Z Output polarity : Positive : 11.1g Calibration date : 216//1 Calibration frequency : 19.2 Hz Calibration temperature : 2. ºC NP-1N2 TEDS Adapter using NP-1N2 adapter between the accelerometer TEDS equipments. This adapter easily enables an accelerometer with built-in preamplifier to be TEDS applicable sensor. By using this adapter, there is no need to embed TEDS tip in the sensor itself. You can use the sensor as TEDS applicable one while keeping the features of each sensor such as ultra compact lightweight. NP-1N2 TEDS adapter Conventional procedure for measurement 1) Make the correspondent table of measurement points sensor sensitivities while mounting sensors. 2) Tag the both side of cables with careful attention not to make a wrong connection. ) Lay the cables check the disconnection. 4) Connect sensors to amplifiers in order while checking the each tag. ) Setup the sensitivity of amplifier or analyzer. 6) Start measurement. Preparation for measurement using TEDS applicable sensors 1) Lay the cables. 2) Read TEDS information to complete the checking disconnection setting the sensitivity. ) Start measurement. Connect to TEDS applicable amplifier or analyzer. Do you figure out each connection of measurement point sensor? Is the sensitivity setup correct? The CE marking on a product indicates that the target product satisfies the requirements on each directive prescribing the health safety protection of users consumers of products, which is based on the New Approach Directive (European Common Law) established by the European Commission. To conform to CE marking ensures distribution selling freely in the European Union, can be said that it is a proof of trust. At multipoint measurement, TEDS greatly helps to reduce the setup time. Also it is effective at single point measurement.
