MEMS Medium High Range Shock Sensor

JSSM9S0 High-G Shock Accelerometer 

Capture Extreme Impact Events with Precision

The JSSM9S0 High-G Shock Sensor is a leading-edge product for impact testing that combines toughness and accuracy in capturing the highest g shocks. This state-of-the-art MEMS Shock Accelerometer offers a wide measurement range of up to ±10,000g and a bandwidth of 10 kHz, making it perfect for use where regular sensors cannot work due to the severity of the vibrations. The durable Titanium Alloy Accelerometer casing made of premium TC4 titanium achieves a rare combination of extreme strength and ultralow weight.

Equipped with sophisticated MEMS variable capacitance technology at its core, this rugged 10000g Accelerometer offers < 0.02 linearity < ±2% FSO) and a high level of operational stability under the most extreme environmental stress conditions. Monolithic titanium housing and 3D-packaged sensor elements perfectly complement each other in providing the features associated with the highest standard of performance. Thus, this Impact Testing Sensor is the best equipment for ballistic testing, explosive impact monitoring, and high-G mechanical shock experiments.

Ultra-wide measurement range: ±1,000g to ±10,000g

Wide frequency response: 10 Hz to 10 kHz
Unrivalled shock survival: 20,000g on any axis
Low noise density: 10 mg/√Hz
High temperature operation: -40°C to +125°C
Compact lightweight design: 13g

The High-G Shock Sensor is tailor-made for applications in defense systems, car crash tests, and before & after industrial machinery monitoring situations, where it is always crucial to catch very short-lasting, high-magnitude shock wave peaks. The MEMS Shock Accelerometer assures quantitative verification of explosive gases, pyrotechnic shocks, and mechanical impacts that would render a normal device unusable. A Titanium Alloy Accelerometer concept considerably improves the features of anti-corrosion and mechanical strength of the sensor.

The JSSM9S0 is an all-in-one 10000g Accelerometer which provides multiple range configurations to meet the test requirements of any experiment. Furthermore, AC coupling removes the low-frequency drift and retains the high-frequency shock signals. So it is the most suitable Impact Testing Sensor for the transient event capture. 20,000g shock survival rating gives an extensive safety margin and ensures sensor security in extreme conditions.

Due to the extraordinary capacity of the range, sturdy titanium casing, and the advanced MEMS tech packed in a single unit, the JSSM9S0 counts among the best High-G Shock Sensor products on the market. Keep your measurements continuous and reliable with this top-of-the-line MEMS Shock Accelerometer that is designed to work under the greatest acceleration levels. Allowing user control of three different input amplification ranges and frequency responses, it is a remarkably flexible ‍‌‍‍‌‍‌‍‍‌device.

1.‍‌‍‍‌‍‌‍‍‌ Q: What makes this a true shock sensor instead of a general vibration sensor? 

A: Its combination of a very high measurement range (up to ±10,000g) and wide bandwidth (up to 50 kHz) is especially targeted at recording extremely short and high-amplitude shock pulses, which ordinary vibration sensors are not able to measure properly.
2. Q: Why is titanium alloy (TC4) used for the housing?

 A: TC4 titanium offers a great compromise between a high strength-to-weight ratio and outstanding corrosion resistance, which helps the sensor to be physically strong in harsh military and industrial environments, yet lightweight.

5. Q: The frequency response starts at 10 Hz (AC-coupled). Why is this acceptable for a shock sensor?

 A: True mechanical shocks do not have much energy at very low frequencies (<10 Hz). The AC-coupling (which acts as a high-pass filter) is capable of efficiently getting rid of low-frequency drift and tilt components, thus providing a perfectly clean and stable baseline for the recording of the high-frequency shock transient ‍‌‍‍‌‍‌‍‍‌only.
