A multifunctional signal isolation converter () is arranged in a safe area (), and is applied to an electronic apparatus () arranged in a dangerous area (). The multifunctional signal isolation converter () includes a microprocessor () and a power supply unit (). The microprocessor () determines whether internal functions of the multifunctional signal isolation converter () are normal or not to obtain a first judgment value. The electronic apparatus () sends an input signal () to the microprocessor (). The microprocessor () determines whether functions of the electronic apparatus () are normal or not to obtain a second judgment value according to the input signal (). The microprocessor () controls whether the power supply unit () supplies a driving power () to the electronic apparatus () or not according to the first judgment value and the second judgment value.

A conveying apparatus () includes a dynamic axis (), an idler axis (), a conveying belt (), a work-energy conversion wireless monitoring apparatus () and at least an on-site wireless controller (). The on-site wireless controller () is used to sense an operation status of the conveying apparatus () to generate a sense data () and to wirelessly send the sense data () to the work-energy conversion wireless monitoring apparatus (). The work-energy conversion wireless monitoring apparatus () includes an electric generator (), a battery (), a rotating speed measuring sensor (), a microprocessor () and a transmission antenna (). The electric generator () is coupled to and connected to the idler axis (). The electric generator () is driven with a rotating motion of the idler axis () to generate an electricity power. The battery () is electrically connected to the electric generator ().

Conveying apparatus

A level transducer has a power supply module, a tuning fork module, a sensing-phase corrector and a controller. The tuning fork module has a tuning fork, at least one piezoelectric driving element, and at least one piezoelectric sensing element. The at least one piezoelectric driving element and the at least one piezoelectric sensing element are stacked on each other, and are mounted on the tuning fork. The power supply module is electrically connected and outputs a voltage to the at least one piezoelectric driving element to deform the at least one piezoelectric driving element. The at least one piezoelectric sensing element is extruded and outputs a voltage signal. The sensing-phase corrector obtains the voltage signal and outputs a clock signal to feedback control the voltage on the at least one piezoelectric driving element to optimize a deformation frequency of each piezoelectric element.
