Capacitive MEMS, Single Axis Accelerometer

Type 8315A … is a high sensitivity, low noise, single axis ac-

celerometer family which measures acceleration and/or low-

frequency vibration in the primary sensing axis. The acceler-

ometer features include:

• Measuring ranges: ±2 g, ±10 g, ±30 g, ±50 g,

±100 g, ±200 g

• Frequency response: 0 ... 1000 Hz (5 %) (except ±2 g)

• Bipolar ±4 V, single ended 2.5 V ±2 V and ±8 V

differential accelerometer output options

• Operating temperature –65 … 250 °F

• Low noise

• Excellent thermal stability

• 1 x 0.85 in. footprint

• Wide supply voltage range, 6 … 50 VDC

• 6000 gpk shock rated

• Conforming to CE

Description

The 8315A … Capacitive Accelerometer family utilizes a sili-

con Micro-Electro-Mechanical System (MEMS) variable ca-

pacitance sensing element. The sensing element of 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 demodu-

lation 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 a volt-

age which is proportional to the applied acceleration.

There are 3 housing/electrical interface options (AC, TA, TB)

which determine the available output signal formats. The ac-

celerometer 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 tem-

perature range is +185 °F and the available output signal for-

mats are bipolar 0±4 V, single ended 2.5±2 V and differential

0±8 V. The sensing element and electronics are contained in

this lightweight housing with an environmental seal and inte-

gral ground isolation.

The TA and TB options offer a welded titanium housing with

either an industry standard 4-pin, ¼-28 connector or integral

jacketed cable. The maximum temperature range

is +250 °F and the available output signal formats are bi-

polar 0±4 V (with temperature output) , single ended 2.5

±2 V (with temperature output) and differential 0±8 V. Tem-

perature output is provided if external compensation of the

output signal is desired. The sensing element and electron-

ics are contained in a lightweight, welded titanium housing

for a fully hermetic design with integral ground isolation. For

adhesive mounting, the hard anodized plate, at the bottom of

the sensor provides ground isolation. For screw mounting, the

sensors are supplied with integral isolation inserts in the screw

holes to ensure a ground isolated mount in combination with

the hard anodized plate on the bottom of the sensor.

Application

The 8315A … is an instrument grade, single axis accelerom-

eter. As such, the 8315A … is well suited for a wide variety of

R&D and OEM applications requiring precision measurements

and packaging designed for demanding application and han-

dling 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 often evaluates system parameters

such as vehicle ride, dynamics and structural analysis to as-

sess performance parameters, reliability and durability. Civil

engineering structures such as bridges often are evaluated for

structural response to assess the integrity of the bridge to en-

sure safety. Seismic ground and structural testing is often per-

formed to measure the effect of earthquakes and other natural

phenomena. Other R&D studies include human motion stud-

ies, robotics and platform motion control systems for example.

Mounting

Reliable and accurate measurements require that the mount-

ing surface be clean and flat. The accelerometer can be directly

attached to the test structure with the supplied screws for a

ground isolated mount or with adhesive. Several optional ac-

cessories are offered to mount the 8315A … The 8464K01

is an adhesive mounting base with 2, 4-40 threaded holes to

mount the sensor with the supplied screws. The 8464K02 is

similar to the 8464K01 except is has a threaded 10-32 hole to

provide a ground isolated stud mount. The 8464K03 is similar

to the 8464K01 except it provides magnetic mounting for the

sensor. The 8522 is a triaxial mounting cube which is used to

provide a biaxial or triaxial solution for the 8315A family of

sensors. The instruction manual for the 8315A … provides

detailed information regarding mounting surface preparation.
