Alarm device and alarm device of water level and water temperature

摘要

Topic Offer of alarm device and alarm device of water level and water temperature.SolutionsThe alarm device of water level and water temperature, the water temperature sensor, the level switch, has alarm display unit and operation unit, aforementioned operation unit, the water temperature sensor, is jointed to the level switch and alarm display unit. The level switch, as the 1st electrode dot and it is jointed to the 2nd electrode dot, when the 1st electrode dot and short circuit is generated in the 2nd electrode dot, outputs the trigger signal to operation unit. Operation unit as the trigger after being done, the water temperature signal is received from the water temperature sensor with the trigger signal, in order to give out the light color which differs, Drive alarm display unit on the basis of the temperature scale which corresponds to the temperature of the water temperature signal. As for the aforementioned alarm device, furthermore, to transmit to the remote mainframe or the communication device it is possible the signal of water temperature and electrical quantity.
