  • Detail

Kionix launched three-axis acceleration sensors that can process sensor signals and filter noise. These two products are three-axis acceleration sensors that are very suitable for machine health monitoring such as motor vibration analysis of industrial equipment. Equipped with the unique advanced data path (hereinafter referred to as "ADP"), it can flexibly process the sensor signal processing and noise LDI and dl-la filtering previously carried out on the microcontroller end at the acceleration sensor end. Because

in recent years, because many factories are trying to save manpower and improve efficiency, the predictive maintenance concept that can detect abnormalities before industrial equipment fails is becoming more and more popular. At the same time, machine health monitoring has also attracted more and more attention. As a component for condition detection, the importance of sensors has increased year by year. In the past, Kionix mainly developed small acceleration sensors for mobile devices. In the future, it will meet a wider range of social needs by expanding the product lineup for industrial devices

these two products are triaxial acceleration sensors that are very suitable for machine health monitoring such as motor vibration analysis of industrial equipment. Equipped with the unique advanced data path (hereinafter referred to as "ADP"), it can flexibly process the sensor signal processing and noise filtering previously carried out on the microcontroller at the acceleration sensor end, so it helps to reduce the burden of the controller, reduce the power consumption of the application and improve the performance of the application. In addition, for industrial equipment, high acceleration vibration detection with induction frequency band up to 8500hz and acceleration up to ± 64g can be realized, and the working temperature range can also be increased to 105 ℃. Moreover, the current consumed by the sensor monomer is less than half that of Kionix's previous products (only 0.67 a in low-power mode). In addition, it is also equipped with wake up function and back to sleep function, which helps to further reduce power consumption and supports the sensing of battery driven devices such as wearable devices

it is understood that this product has been applied to the integrity, predictive maintenance and condition/vibration monitoring of industrial equipment equipped with motors (machine health monitoring); Wearable devices; Logistics tracking combined with GPS; Automobile smart key, etc

this product has the following characteristics:

1. Realize low-power consumption of components and applications at the same time.

compared with previous products of Kionix, the current consumption of these two products is less than half (only 0.67 a in low-power mode). In addition, it is newly equipped with the wake up function that automatically starts from the sleep mode during acceleration detection, and the back to sleep function that enables the wear comparator of micro control and simulation test to switch to the energy-saving mode when acceleration detection is not carried out within a certain period of time, which can further reduce the power consumption of the micro controller. In this way, not only the power consumption of the acceleration sensor is lower, but also the static power consumption of the microcontroller can be reduced, so that the overall work efficiency of the application is higher, which is conducive to the long-term operation of battery driven applications such as wearable devices and car smart keys

2. Equipped with the unique ADP (advanced data pass) function, it helps to reduce the burden of the controller.

adp is an original new function of Kionix that replaces the filtering function of the microcontroller. Specifically, it is composed of a number of customizable frequency filters built into the sensor, which reach the domestic leading and international advanced level in several fields, such as large-size monocrystalline silicon wafer, ultra-high purity metal sputtering target, optical film, new cobalt materials, rare earth permanent magnet materials, high-purity electronic and chemical materials, so as to eliminate unnecessary noise interference signals and extract only the required signals. In addition, since each filter can be switched on/off, the basic point of application is sensitivity. The frequency analysis and noise filtering functions previously carried out at the microcontroller end, including FFT analysis of sensor signals, will be able to be carried out at the acceleration sensor end, so it can flexibly transmit the required data, reduce the burden of the controller, reduce the power consumption of the application and improve the performance of the application

3. It is very suitable for machine health monitoring of industrial equipment

kx can detect the frequency band as high as 4200Hz, the acceleration (g) range is as wide as ± 2G ~ ± 16g, and the high-end product KX can detect the frequency band as high as 8500hz, the acceleration (g) range is as wide as ± 8g ~ ± 64g. In addition, compared with the previous products with a maximum working temperature of 85 ℃, these two products can also work normally in an environment as high as 105 ℃. The product lineup not only supports high-temperature work, but also supports a wide range of frequency and acceleration detection, so it is very suitable for machine health monitoring purposes such as motor vibration analysis of industrial equipment

this series of products has been put into mass production on a scale of 100000 pieces per month since September 2019 (the sample price is 1500 yen/piece, excluding tax). In the future, Kionix will further expand the lineup of high-precision and low-power sensor products and contribute to the development of IOT in society
