Instrument exports Europe and the United States is more of a thermometer is boiler thermometer, what is it? We'll take a look today. This thermometer is usually installed on the boiler hot water boiler system on exports, manifold and Siamese, and installed on the total return water main. Is mainly used to test the water temperature and return water temperature, convenient operation personnel according to temperature condition of boiler operation, the control requirements of water supply. Glass mercury thermometer can be installed in both horizontal and vertical pipe runs, when installed in vertical pipe runs, can with the tube center into 30 Angle & deg; ,45度; 90度; Wait for a variety of installation location, installed in horizontal pipe runs for vertical installation, bulb parts should be at the center of the pipe, surface should be easy to observation direction installation time. If it is a double metal thermometer, mainly through the nut or flange installation on equipment or pipeline, through the test tube directly detect the medium temperature. If it is a pressure type thermometer, mainly by the heat pack, capillary and the spring pressure gauge. Capillary set within the metal hose, thermal package installed in the interface of tested medium, hot water boiler is generally installed in the hot water outlet, metal hose shall not be close to hot surface area to avoid affect its accuracy, hose bend less as far as possible, and redundant hose rolled into the case, according to temperature stress dial may be placed on a lower position for easy reading. Pressure type thermometer is suitable for measuring the temperature of the medium over a long distance, installed in the hot water boiler exit. The commonly used hot water boiler is the industrial glass mercury thermometer thermometer, bimetallic thermometer and pressure type thermometer. Is made no mention of industrial glass mercury thermometer and share standard type glass mercury thermometer and rod type glass mercury thermometer, used for hot water boiler system, the first rod type used to test the liquid or gas temperature, internal standard type is in the glass tube filled with a certain amount of mercury, and then into a vacuum, when inserted were test medium temperature package heat expansion of mercury, the mercury glass tube liquid level increases, or the temperature drops and the liquid level down, and mark it in a metal sheath tube temperature scale, according to internal standard to measure the medium temperature type glass mercury thermometer. There are also many boiler thermometer specifications and according to the specific installation of the boiler we customize different boiler with a thermometer.
