Measurement Specialties recently introduced the 4610A, a versatile sensor with integral temperature compensation for both static and dynamic measurements.

The 4610A is a rugged, ultra-low-noise DC accelerometer that measures shock and vibration levels up to 2,000g's via an integrated gas damped MEMS element with mechanical overload stops. It is useful for detecting low frequency, low amplitude vibration in a variety of applications, including structural monitoring, road vehicle testing, transportation and machine control.

Operating over a wide temperature range of -55°C to 125°C, the device is offered in ranges from ±2g to ±100g with a flat frequency response to 1,500Hz. The sensor incorporates an ultra-low-noise amplification circuit for a ±2 V DC full-scale output with a dynamic range of 97dB.

The accelerometer features a signal-conditioned, DC-coupled output and can be configured in single-ended mode or in differential mode for higher performance applications, where good common mode rejection is desirable. Excitation voltage ranges from 8VDC to 30VDC, with an excitation current of less than 12mA.

Housed in an anodized aluminium package, the 4610A is suitable for use in rugged environments. The unit is epoxy sealed to IP62 specifications and the flexible cable assembly is constructed of a TPE-jacketed cable with an integral braided shield and PFA-insulated leads. A triaxial configuration is offered in the model 4630A package.

Further information regarding the 4610A accelerometer can be found here.
