Figure 1.1 Overall view of ZET 7152-N-VER.3
ZET 7152-N-VER.3 is a complex multi-functional measuring complex, which includes:
1. ZET 7156 digital short-period seismometer
Digital short-period seismometer ZET 7156 is used for vibration velocity measurements of
high structures (bearing and enclosure structures) and underground structures (foundations, piles,
etc.). The seismograph consists of three identical sensing elements and a measuring module. The
sensing elements detect low-frequency mechanical oscillations by three mutually transverse axes
(X, Y and Z) and convert them into analog signal. The measuring module, in its turn, performs
digital processing of the analog signals and transfers digital data via CAN 2.0 interface.
2. Digital accelerometer ZET 7152-N
Digital accelerometer ZET 7152-N is used for measurements and conversion of acceleration
into a digital signal and further transfer of the data in digital format. The accelerometer consists of
a vibration sensor with integrated triaxial sensing element, which converts acceleration value into
a digital code by three mutually transverse axes X, Y and Z.
3. Off-line recorder ZET 7173
Off-line recorder ZET 7173 is used for recording the data obtained from digital sensors of
ZET 7152-N-VER.3. Data recording starts automatically as ZET 7152-N-VER.3 is switched on.
The data is saved to a microSD card as files in special format.
4. Synchronization module ZET 7175

Synchronization module ZET 7175 is used for synchronization of sensors time with global
time.
5. Interface converter ZET 7176
Interface converter ZET 7176 is used to connect the digital sensors of ZET 7152-N-VER.3
to PC via Ethernet interface as well as to configure digital sensors parameters.
6. Integrated battery
ZET 7152-N-VER.3 has an integrated battery allowing to record the registered signals to
non-volatile memory for further analysis by means of PC. ZET 7152-N-VER.3 data is transmitted
via Ethernet in real-time mode. Battery capacity enables measurements during 18 hours.
