EM-82-50B is a MEMS-based acceleration sensor designed for vibration measurement and monitoring applications requiring a high acceleration range. MEMS technology provides good long-term stability, shock resistance and a linear frequency response.
The sensor has a nominal sensitivity of 40 mV/g and a 2.5 V output offset. Its aluminium housing and moulded sensor construction provide IP67 protection for use in demanding industrial environments.
The acceleration signal is provided as an analogue voltage centred around a nominal 2.5 V offset. The specified output swing is ±1.4 V, resulting in an output range of approximately 1.1–3.9 V.
The nominal sensitivity is 40 mV/g, corresponding to approximately 4.07 mV per m/s². The buffered output helps maintain signal quality and interference tolerance when using the supplied 6 m cable.
The sensor has a specified frequency response of 5–500 Hz within ±3 dB. Within the narrower range of 10–400 Hz, the specified amplitude variation is ±5%.
The sensor body is manufactured from aluminium, and the sensing element is moulded into the housing. The enclosure is rated to IP67.
