Low-noise accelerometer calculates static and dynamic signals
Measurement Specialties released the 4610A, a versatile sensor with integral temperature compensation for both static and dynamic measurements. This ultra low-noise DC accelerometer measures shock and vibration levels up to 2,000 g’s via an integrated gas damped MEMS element with mechanical overload stops. It is particularly 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 new 4610A is offered in ranges from ±2 g to ±100 g with a flat frequency response to 1,500 Hz. The sensor incorporates an ultra low-noise amplification circuit for a ±2 VDC full-scale output with a dynamic range of 97 dB. 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 8 VDC to 30 VDC, with an excitation current of <12 mA.Housed in an anodized aluminum 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.
