Ono ONOSOKKI structure and principle of the acceleration sensor:? When the effect of the single crystal or crystal of barium titanate by the force, which will produce a surface charge, i.e. the so-called piezoelectric effect. Can produce material piezoelectric effect, which we call the pressure? Dielectric material or a piezoelectric element. ? Piezoelectric acceleration sensor using a piezoelectric element as the vibrator of the reed as the mechanical energy into electrical energy, the vibration acceleration is proportional to the electrical signal out. ? According to different piezoelectric elements, piezoelectric accelerometer force approach can be divided into compact and shear it is basically two categories, which were constructed as shown above. ? Configured compression type piezoelectric sensor is a piezoelectric element sandwiched between the weight and the sensor base, the piezoelectric element is pressurized to generate a charge. The shear structure is perpendicular to the base pillar, the piezoelectric element sandwiched between the pillar and the weights, weight of gravity shear piezoelectric element generates an electric charge. Previous acceleration sensor, using compression more, but in recent strain and ambient temperature is less affected by changes in the base shear mode piezoelectric sensors gradually tend to spread. The company in addition to a small portion of the piezoelectric sensor is compact, the rest are mostly cut type. Ono detector inputs in terms of vibration measurements, product and more complete series. Products include vibration signals captured from the beginning of the acceleration sensor to measure the natural frequency and modal analysis impact hammer; from high-sensitivity vibration testing of a laser Doppler vibrometer probe began, to a variety of vibration data parsing analyzers, everything, not only to meet the various needs of users, in addition to provide customers with vibration measurement and analysis of the entire system, and to provide the vibration measurements, including how to resolve technical advice. NP-7310 accelerometer description:? NP-7310 built-in preamplifier that can simultaneously detect three-dimensional acceleration sensor vibration. ?

Speed ??meter in accordance with the principle and work in different ways, can be divided into several types of centrifugal tachometer, magnetic tachometer, electric tachometer, magnetic tachometer, tachometer and flash electronic tachometer. ?? A centrifugal tachometer? Centrifugal tachometer is a balance and tension to the principle of centrifugal force to measure the motor speed. Measurement accuracy is low centrifugal tachometer, usually in 1-2, but is easy to install, easy to use. Advantages centrifugal tachometer to measure intuitive, easy reading, stable operation, good reliability, the disadvantage is that the structure of the complex. ?? 2,2, magnetic tachometer? Magnetic tachometer is a rotating magnetic field to measure the motor speed to the principle of a class tachometer. When measuring magnetic tachometer speed, according to the size of the speed of the rotational force generated with gossamer force balance, to indicate speed value. Magnetic tachometer simple structure, easy to use, and more for motorcycles and cars and other equipment. ?? 3,3, electric tachometer? Electric tachometer is a measure of the way, is a small AC motor speed, keeping consistent with the measured shaft speed, and the speed of the magnetic head and a small AC coaxial rotation again, so magnetic speed head speed indicated is measured shaft speed. Electric tachometer suitable places to install, good shock resistance, and more for speed measurement equipment such as diesel engines and ship. ?? 4,4, magnetic tachometer? Magnetic tachometer is the use of a magnetoresistive element to complete a tachometer speed measurement. Works magnetic tachometer is reluctance impedance value varies with the strength of the magnetic field, when the gear shaft close to the measured magnetic tachometer, with gear tooth addendum Valley will make changes in the magnetic field, so that the magnetic electric tachometer by measuring the change in resistance can be measured response speed of the shaft. ? 5, 5, flash tachometer? Flash tachometer is based on the principle of persistence of vision of a tachometer device. Flash tachometer function is more abundant than ordinary tachometer, except reciprocating speed can be measured, but also for reciprocating still observing objects, machinery and equipment movement, one of the essential instruments working condition observations. ?? 6,6, electronic tachometer?
