Designation
of digital accelerometers ZET 7152-N Pro
Digital accelerometer ZET 7152-N Pro is intended for vibrational acceleration recording in the scope of stationary systems used for control of the industrial machinery vibration. This digital accelerometer is perfectly suitable for permanent installation and long-term monitoring in the real-time mode.
The accelerometers are mounted on the controlled object and thus form the measurement lines. Compact dimensions of the transducers allow to implement vibration monitoring in hard-to-reach areas.
The system based on these digital transducers is scalable, which means that it can be expanded by means of adding additional transducers to the measurement line.
Connection schemes
of digital accelerometers ZET 7152-N Pro
It is especially convenient to use the digital transducers for deployment of distributed measurement networks. The difference from the traditional centralized measurement networks is that there is no need to use “wye”-type connection, which allows to considerably reduce the overall length of the measurement networks. Since the data is transmitted in digital form, there are less requirements to the data channel, and it is also possible to use relatively inexpensive cables.
In the course of the measurement network deployment, transducers ZET 7152-N Pro are to be connected sequentially, and the resulting measurement line is connected to the PC with the use of interface converters: ZET 7174 (CAN ↔ USB), ZET 7176 (CAN ↔ Ethernet или Wi-Fi), or ZET 7177 (CAN ↔ GSM).
