Boiler thermometer should be how to choose is correct?

Instrument production thermometer often exported to foreign countries, especially some European and American countries, from the perspective of a regular supply product exports the most a thermometer is boiler thermometer, but recently had a customer ask, to use the thermometer there are many kinds of boiler, how should be the right choice? Instrument to introduce below: boiler thermometer are normally installed in the 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. The commonly used hot water boiler is the industrial glass mercury thermometer thermometer, bimetallic thermometer and pressure type thermometer. 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. Above is commonly used on boiler thermometer, in addition, there are also many different boiler thermometer specifications, appearance can be customized according to the specific installation of boiler different boiler with a thermometer.
