• The MEMS capacitive single axis accelerometer family provides a highly accurate measurement of low-frequency events from DC up to 2000Hz.
• Its ground isolated base, thermal stability, rugged design, and low noise make the K-Beam 8316A MEMS capacitive single axis accelerometer ideal for automotive durability testing and road load data, bridge structural testing and monitoring as well as railway rolling stock testing and monitoring.
• Available in g ranges from 2g up to 200g, with a wide analog output and cable configurations, the 8316A sensor family should suit most of your configuration needs.
• A MEMS capacitive triaxial accelerometer, type 8396A… is also available in our portfolio.

Description

• The Type 8316A… capacitive accelerometer family utilizes a silicon Micro-Electro Mechanical System (MEMS) variable capacitance sensing element. Each axis consists of a very small inertial mass and a flexure element cantilever positioned between two plates. As the mass deflects under acceleration, the capacitance between these plates changes. AC excitation and synchronous amplitude demodulation circuitry contained in the accelerometer’s internal signal conditioner provides an analog output signal proportional to the applied acceleration. This output signal is scaled as voltage and is proportional to the applied acceleration.
• There are three housing/electrical interface options (AC, TA, TB), which determine the available output signal formats. The accelerometer is powered by a single regulated supply between 6 and 50 VDC. The AC option is a hard anodized aluminum housing with an epoxy seal and an integral PVC cable. The maximum temperature range is 85°C [185°F].
• The available output signal formats are bipolar 0±4 V, single-ended 2.5±2 V, and differential 0±4 V or 0±8 V. The sensing element and electronics are contained in this lightweight housing with an environmental seal and integral ground isolation

Application

• Type 8316A… is an instrument-grade, single-axis accelerometer. It is well-suited for a wide variety of R&D and OEM applications requiring precision measurements and packaging designed for demanding application and handling needs.
• In particular, the sensor design is optimized for low frequency applications common to Aviation/Aerospace, Automotive, Civil Engineering Structures, Seismic and other R&D studies. In particular, Aviation/Aerospace ground and flight testing often evaluates dynamics and structural vibration to assess performance parameters, reliability and integrity. Automotive laboratory and road testing evaluates system parameters such as vehicle ride, dynamics and structural analysis to assess performance parameters, reliability and durability. Civil engineering structures such as bridges are often evaluated for structural response to assess the integrity of the bridge to ensure safety. Seismic ground and structural testing are performed to measure the effects of earthquakes and other natural phenomena. The differential output versions are being used for railway comfort or conditional maintenance monitoring applications where halogen-free cables are requested as well. Other examples of R&D studies include human motion, robotics and platform motion control systems.
