Accelerometer with onboard signal conditioning is designed for very low frequency measurements in instrumentation, test, aerospace and automotive applications.

Measurement Specialties' new Model 4610 accelerometer with onboard signal conditioning is designed for very low frequency measurements in instrumentation, test, aerospace and automotive applications.

Offering integral temperature compensation with a hermetically sealed sensor assembly, this accelerometer is available in ranges from +/-2 to +/-500g with a bandwidth from DC to 1500Hz.

The Model 4630 offers the same high performance sensing technology in a triaxial package with independent circuits and low transverse sensitivity.

Applications for the 4610 and 4630 accelerometers include low frequency uses such as flight testing, vibration/shock monitoring, motion analysis, transportation (such as trains), road vehicle testing, machine control and modal analysis.

The Models 4610 and 4630 use Measurement Specialties' second-generation MEMS technology that ensures exceptional long term stability and wide dynamic range.

Fully shielded electrically, the rugged, screw-mounted anodised aluminium packaging was specifically designed for severe vibration environments where accurate, reliable measurements of shock and vibration motion are required.

The accelerometers operate from a 8-32V DC power supply with minimal power consumption and provides an optional 2.5V reference voltage.

Models 4610 and 4630 have an operating temperature range of -40 to +115C and offer a standard thermal zero and sensitivity shift of +/-0.019%FSO/C maximum from (tighter options available on request).

Either with the standard integral cable or connector options, measurement professionals will find Models 4610 and 4630 ideal for both static and dynamic applications.

The underlying MEMS technology and the innovative design for this sensor stems from Measurement Specialties' research and vibration design facilities in Fremont and Aliso Viejo California.
