Eugster Abstract. Seismic detector systems take advantage of the fact that all tools used by burglars in their attempt to gain access into a vault create sound waves propagating through the wall usually constructed of steel, reinforced concrete or equivalent material. The system uses a radar‐based displacement sensor for the measurement of seismic displacements. The radar system performed well, but had two significant issues for a practical mine detection system; the antenna for this radar had to be placed within a few centimeters from the surface to get the required spatial resolution, and the scanning This detectability for earthquakes far below noise level is rarely seen with regular seismic arrays and conventional detection methods (Li et al. 2018).

It meets the requirements of the construction standard BS7629-1 as certified by BASEC and also the ‘enhanced’ fire resistance standard BS8434-2, certified by LPCB.

In hard rock, water- and air-filled cavities or abruptly changing weak zones in the rock represent a potential source of danger. These problems can be detected at an early stage by Herrenknecht‘s exploration system ISP (Integrated Seismic Prediction).

They are designed to meet fire and safety requirements of the NEC, CEC, UL, CSA and EN. The quality system at the manufacturing facility in Rocky Mount, NC, is ISO-9001 certified. Draka ‘seal of approval’ partners meet our requirements for quality and durability. Se hela listan på sensoguard.com Seismic Detection Systems provide sensor-level decision making that allows indepentdent sensor processing for pinpoint accuracy. Its adaptive intelligent algorithms continuously learn the behaviour of the environment, leading to fewer false alarms and highest detection probability.

Based on the same sensitive seismic technology used for earthquake detection, the system recognizes threats in its vicinity. Our underground detectors are manufactured in compliance to strictest military standards, rendering them completely functional year-round, even under extreme weather conditions.

[1] An array of radars is developed as a standoff sensor for use in seismic/elastic mine detection systems. The array consists of N radar sensors which operate independently to sense the displacement of the surface of Earth due to elastic waves propagating in Earth. Each of the sensors consists of a lens-focused, conical, corrugated, horn antenna and a
