Solar Thermal Systems

Our earth get much light energy from sun, now the solar engineer converting technology are very popular in the world, to alternative gas, oil and electrically powered heating system, beside its an constituent components for an ice storage heating system, the solar plant work out light to heat, it's great solution to save our earth, for testing the system temperature and water pressure XY-PG210 are good solution to show them in one plate at same time, it output 4-20mA single for furfure  analysis and control, If we need shut down the solar circuit pump and avoid storage vessel was damaged because of overheating, the XY-PS628E Digital Pressure Switch can shut down it by its dual relay output.
