An accelerometer is a sensor that detects acceleration or vibration by attaching or coming into contact with the body of machinery or equipment that is vibrating. TYPE 7803A , NI USB-9234, NI 9234, NI USB-9162, NI USB-9234

ACO Co., Ltd. offers a variety of accelerometers, including the TYPE 7302, which weighs only 1/5 of a 1 Yen coin (0.2g), and others with a temperature range of -50oC to +160oC, meeting a wide range of needs. different needs by customers. With the integrated preamplifier type accelerometer, an expensive separate amplifier is not required and can be expanded using a low noise connection cable, thus reducing measurement costs.

Piezoeletric Type Acceleration Pickup Built-in Preamplifier Type Acceleration Pickup

CASE STUDY

In general, acceleration pickup has a main axis with which the acceleration sensitivity becomes its maximum. It is called “Sensing Axis” and align this axis with the desired measurement direction. Normally the sensing axis is close to perpendicular to the mounting base surface of the pickup.
With the pickup fixed to the vibration table and if it is vibrated in the direction of sensing axis, the pickup will provide output rating. Next, if the pickup is mounted on the vibration table with inclination angle θ for the sensing axis and vibrated, the output (SVθ) will be rated output multiplied by cosθ, Output sensing for the axis will be SVθ*cosθ. If the θ is brought to 90 degrees, the output is supposed to become zero however, because of the existence of the Transverse Sensitivity (ie Sensitivity in any given direction perpendicular to the sensing axis), there will be some output. In the case of pickups offered by ACO, the lateral axis sensitivity is less than 5%.

Triple axis pickup is very useful since it can measure the vibration in 3 axis simultaneously. It is a convenient sensor to obtain composition of acceleration in 3 axes, or to measure and evaluate human body exposure to the vibration of machinery.
New product, 3 axis 10 mm X 10 mm, was developed in response to the need to use the pickup at measurement site where only small mounting space is available. It contains preamplifier yet it
