PURPOSE AND OPERATING PRINCIPLES

of Telemetering system ZET 7172

ZET 7172 telemetering system is used to provide wireless access to the instrument line segment using radio channel.

Telemetering system includes two modules: ZET 7172-M and ZET 7172-S.
ZET 7172-S module is mounted proximal to measuring modules and functions as a data transmitter, converting the CAN interface into radio-channel. In turn, ZET 7172-M module receives data over the radiochannel and transduces it into CAN interface for further translation of measured information to PC, where it is further processed and analyzed. It functions as a receiver, installed proximal to interface converter.

Measured information is transferred only one way from ZET 7172-S transmitter to ZET 7172-M receiver, but service information is transmitted in both ways, which allows adjusting measuring modules proximal to ZET 7172-S transmitter.

ZET 7172-S module has an integrated linear accelerometer. This option is convenient when testing rotating constructions, as it permits to minimize the content of instrument system and provide wireless data transmission.

Module ZET 7172-S is mounted on the rotating element in such a way so that Z axis of the integrated transducer ZET 7152-N would be transverse to the rotation axis and Y axis would be aligned with the curve of the shaft. As the shaft is rotating, the transducer calculates the linear speed by Y axis. The number of rotations is calculated by means of ZETLAB Software programs.
