Accelerometer
Kit with digital display and vibration sensor for predictive maintenance / Digital display 96 x 48 mm multi-signal with 4 digits
This Accelerometer is a simple construction device for vibration control in machines and installations. This device detects vibrations caused by balance mismatches, defective adjustments, loose parts, defects in rollers or gears. When the threshold set in the device is reached or exceeded, an alarm is sent or the machine is turned off. Constant control allows early detection of possible machine defects. This in turn allows you to plan in advance the maintenance work, which avoids stopping the machines or the installation, thus avoiding economic losses. The device is used in virtually any industry and machine control sector.
