EM-82-35 is a high-range MEMS acceleration sensor designed for vibration and impact measurement in industrial machinery and monitoring systems. It provides an analog voltage proportional to the measured acceleration.
The sensor has a nominal sensitivity of 40 mV/g and a measuring range of up to ±35 g. Its aluminum housing, wide operating-temperature range and IP67 protection make it suitable for demanding industrial installations.
The EM-82-35 uses a MEMS sensing element to measure dynamic acceleration. MEMS technology provides good long-term repeatability, shock resistance and temperature stability in a compact construction.
The nominal sensitivity is 40 mV/g, corresponding to approximately 4.07 mV per m/s².
At zero acceleration, the nominal output voltage is 2.5 V. Positive and negative acceleration cause the output voltage to move above or below this offset level.
The available output swing is approximately ±1.4 V, giving a nominal output range from 1.1 to 3.9 V. With a sensitivity of 40 mV/g, this corresponds to a full measuring range of approximately ±35 g.
The EM-82-35 is designed for dynamic vibration and acceleration measurements within the following frequency ranges:
The 10–400 Hz range provides the flatter amplitude response, while the wider range extends usable measurement capability from 5 to 500 Hz.
The sensor is specified for continuous operation from −20 to +105 °C.
The sensing element is installed in an aluminum housing and encapsulated for protection against environmental conditions and mechanical stress. The enclosure is rated IP67 and includes a 6 m connection cable.
