Service : Earthquake Recording Instrument (ERI)
Triaxial acceleration meter / Mobile version with NiMH battery / FFT analysis
IP 64 protection / Internal memory for up to 100,000 readings / SMS alert functionality The CE-VM40C EARTHQUAKE RECORDING INSTRUMENT (ERI) or Accelerograph was designed for vibration and shock metering on buildings, bridges, towers, and other artificial structures. The Accelerometer measures vibrations in accordance to DIN 4150-3, BS 7385 and SN 640312A standards.
With its internal memory for up to 100,000 readings, the CE-VM40C Accelerograph can determine the strength of a Seismic event and the effect of construction sites, traffic, or industrial processing on buildings over a long period of time. You can choose between time-based and event-based recording, as well as between recording of short-time and long-time vibrations. It is also possible to set threshold levels which trigger an alarm signal when exceeded. With the built-in GSM module (optional), the device can send you SMS notifications once the alarm is triggered.
