Otronics Seismic Sensor for Elevator Using During Earthquakes

If an earthquake occurs while the elevator is in motion, it is very important for the elevator to probe earthquakes’ wave (P-wave) and meanwhile sends the alarm, even there is only a second. Qtronics Seismic Sensors (QSS) can prevent the device from malfunction and avoid passengers being trapped other risks in such short time for 15 seismic earthquake.
1. QSS can send an alarm signal based on quick detection of preliminary tremor P-waves trough implementation of capacitance sensor to protect the elevator and passengers before the main tremor arrives.
2. Automatically records date, time, duration and peak acceleration in each seismic disturbance.
3. Meter mode allows real-tine monitoring of dinetic force (acceleration).
4. Alarm level set to meet ASCE 25-97 or user-defined thresholds.
5. Easy-to-read and Easy-to-program LCD interface

P-Wave is called the preliminary tremor and its transmission speed is 6 km/sec. By detecting the P-wave and sending the alarm by QSS, it is possible to protect the elevator and the passengers before the main tremor arrives.
S-wave is called the main tremor and its transmission speed is 3.5 km/sec which causes damage to the buildings.
