摘要： A communication isolator configured to perform network communication with a first control system and a second control system includes a first communication device configured to receive a first communication signal corresponding to a first signal with respect to an output from the first control system, obtain first data by decoding the first communication signal, and generate a second signal corresponding to the first data by using a pre-stored look-up table, and a second communication device configured to receive the second signal from the first communication device, convert the second signal into second data by using the look-up table, encode the second data into a second communication signal, and transmit the second communication signal to the second control system.

摘要： A water-level measuring device using a gear ratio includes: a water pool filled with a liquid; a plot receiving buoyancy by being floated over a water surface of the liquid filled in the water pool; a cable connected to the plot and extending to the outside of the water pool; a first gear connected with the cable; a second gear connected with the first gear; a weight pendulum connected with the second gear and moving in up and down directions, wherein when a water level of the water pool descends, the weight pendulum ascends due to a weight of the plot, and when the water level of the water pool ascends, the weight pendulum descends due to the buoyancy of the plot.
