Accelerometer

Many vibration sensing techniques of MSI's piezoelectric technology

A natural product of the application of the device is the accelerometer.

The accelerometer design based on piezoelectric ceramic is very traditional

Porcelain and piezoelectric polymer materials. Selection of basic materials

The choice can be made for the product for a specific purpose. Table 6

The main points of the MSI accelerometer series are listed.

Specifications?

Like a very traditional sensor, these accelerometers can be configured for compression design or beam design. The accelerometer designed by compression usually has a higher resonant frequency and provides a wider useful frequency band. Therefore, their sensitivity is often lower. The internal view of the MSI's ACH01~XX compression design accelerometer is shown in Figure 59.

On the other hand, the accelerometers designed by the beam type are often available.

Lower resonant frequency and useful frequency band, but higher

Sensitivity. The beam type design accelerometer also has another

A very interesting feature: only one MSI is used.

"Origami" beam patented technology ("Origami")

It's a single sense of Japanese, which means the origami process.

The multiaxial acceleration is induced by the orientation of the unit. belt

ACH~04~08~05 beam of Origami induction unit

The internal view of the design accelerometer is shown in Figure 60.


In order to reduce the cost of the system and simplify the use, all MSI accelerometers include some integrated electronic sensor interfaces. ACH~01 accelerometer product series and ACH~04~08~05 multi axis accelerometer using a simple JFET impedance buffer. For these sensors, the JFET bias and signal processing are completed outside the device. The rest of the ACH~04~08 multi axis accelerometer series of products using special ASIC (application specific integrated circuit) to provide impedance matching, gain and signal processing. The system gain, output type (analog or digital quantity) and output shaft can be programmed (by EEPROM on chip), so that sensors can be configured for specific purposes simply. In order to minimize the power consumption, it also includes a SLEEP mode.


ACH~01 products are usually used in applications with wide band, high sensitivity, low noise and low cost. ??????:???????????????????????????????????????????


ACH~04~08 series of products, the performance of wide, and can be used for many purposes, such as computer hard disk vibration induction, speaker feedback and control system, household appliances, fault monitoring, virtual reality systems, automotive systems, medical human movement monitoring system, material handling and transportation damage monitoring system, GPS system, vibration switch and earthquake circuit breaker. The use of ACH-04-08 is ideal for OEM applications of multi axis measurement of acceleration or vibration.


The precision electronics company continues to develop and improve its accelerometer product series. For these products or to order our other products, please contact the precision electronics company in detail.
