Instantel Minimate Plus ground vibration monitor Minimate Ground Vibration Monitor Specifications: The Micromate is the newest ground vibration monitor and possesses an intuitive touchscreen, much larger memory, and better battery life. However, it includes a more robust keypad and internal thermal printer. The Blastmate has the same features as the Minimate. Essentially, the Minimate was the gold standard for ground vibration monitoring for the last 20 years. When requested, these ground vibration monitors can attach a microphone to measure the potential for the damage from air overpressure (e.g an air blast from an explosion).Īll of the ground vibration monitors are similar and are interchangeable for most common appications. Often, mine operators or construction crews measure the peak particle velocity in inches per second to monitor if damage may occur to surrounding structures. This geophone measures the peak particle velocity or the maximum speed of ground vibration as it oscillates about a point of equilibrium caused by seismic energy. Instantel ground vibration monitors such as the Minimate, Micromate, and Blastmate are seismographs that have a triaxial geophone, which consists of one vertical and two horizontal components.
