Seismic Monitoring Station NowTech NT RSS902 EEWS

The measuring tool

The measuring device
stand alone

The NowTech NT RSS902 EEWS monitoring station is a measurement instrument that can be installed standalone in any type of structure or infrastructure, even in free-field environments.

By measuring the ground acceleration generated by seismic waves at the location where the monitoring station is installed, it activates if the effect of even a relatively distant earthquake produces, in the structure, effects equivalent to an event equal to or greater than 4° on the Richter scale (threshold chosen by the Client and based on the building’s construction characteristics).

The unique feature of this system is that the alert is generated upon the onset of the seismic event by measuring acceleration and persistence, thus in advance of the arrival of the most dangerous seismic waves, without waiting for a signal from the server to which the instrument is connected for functional checks and to consult the recorded values.

STRENGTHS

An Early Warning System
seismic in companies
which allows you to limit:

  • Indirect damage caused by the earthquake;

  • The risk of bursting;

  • The timing of restarting production;

  • Workers’ exposure to danger;

  • Environmental impact;

  • Employer responsibility.

It is a damage mitigation garrison that provides valuable seconds for securing property (through appropriately designed actuator devices also for automatic tripping on solenoid valves of facilities, for example) and allows people to reach a less dangerous location within the building.
It is possible to connect the device to the facilities or services, and the wiring can also be carried out by company contracted by the customer.
The instrument in the EEWS version is equipped with 3 outputs so that it can be connected to as many facilities. For additional utilities it will be necessary to be equipped with NT EQG DISPAT_4CH EEWS actuator devices supplied by us upon request.

Our monitoring stations

We boast of decades of experience, without any false positives

In more than 10 years of use, for more than 4.5 million hours of cumulative monitoring over the entire Italian territory, the instrument has never generated false alarms thanks to the special, patented construction system that allows the instrument to be unaffected by extreme anthropogenic or atmospheric elements; the NT RSS902 EEWS Detection Station, measures only ground accelerations and angle variations on the 3 Cartesian axes in the part of the structure where the instrument has been installed.
With the installation of the instrument, the effects of an earthquake on the structure can also be verified and evaluated by providing information about the state of damage (monitoring of the structure’s response to seismic waves) to those responsible for safety. Thus, a time saving.
The NT RSS902 EEWS Seismic/Structural Detector is connected to the proprietary Sentinel server for constant monitoring of its functionality and for user consultation of continuously recorded data.

The installation of NT RSS902 EEWS is particularly simple

The NT RSS902 EEWS detector, which is shown in the following figures resting on the red-colored bracket, is installed in the structural parts of the works by the use of threaded bars of 5mm thickness and varying lengths between 15 and 25cm; the length of the bars depends on the state of the structure and the cement composition.

The nuts and washers seen in the figure allow for easy calibration of the “levelling” of the bracket once the chemical anchor used has hardened.
