Principle of operation
of Vibrating wire interface ZET 7082
The measuring part of vibrating wire interface ZET 7082 has one channel to connect a stringed transducer connection. Together with a sensor, they form a digital sensor to measure various parameters.
The vibrating wire strain gauge converts a physical value to the electric signal while vibrating wire interface ZET 7082 digitizes this signal and outputs the measured variable value in a digital form. Measurement results are transmitted via the RS-485 interface using the Modbus protocol. In combination with other sensors, ZETSENSOR series sensors form measuring lines to monitor engineering systems.
The sensors are fixed on a measurement object, in a sealed box or electric cabinet. The interface modules for data transmission are installed in a sealed box or a ZETLAB electrical cabinet.
The advantages of ZETSENSOR modules are easy installation and uninstallation, the indication of power supply and signal transmission which, in its turn, facilitates diagnostics of the system on a site.
