Monitran MTN/1830 Low Profile IEPE Accelerometer

Manufacturer: Monitran
Category: Accelerometers and Vibration Sensors, Amplified, SENSORS

The Monitran MTN/1830 is a general-purpose, low-profile, side-exit, constant-current accelerometer with isolated AC output. It has a nominal sensitivity of 100 mV/g ±10% at 80 Hz and a frequency response of 2 Hz to 9 kHz ±5% (−3 dB at 0.8 Hz), with a supply current of 0.5 mA to 8 mA and a nominal bias voltage of 12 V DC.

It is manufactured entirely from stainless steel and IP67 rated, with an integral ETFE cable featuring stainless steel overbraiding (5 m standard, 100 m maximum). The product information indicates a ¼" mounting bolt, M6 or M8 in the presentation text, and M6 x 25 mm or M8 x 25 mm in the technical data sheet. Guemisa is an official distributor of Monitran in Spain.
