Plants generally need to what kind of thermometer?

In what is now the rapid development of society, it can be said that each domain can use thermometer, this is the necessity of industrial development. Especially industrial thermometer, such as in power plant, can say, temperature measurement is a top priority. Because: first, to provide operational personnel, accurately and in a timely manner to provide for the automatic control signal, and ensure safe and economic operation, heating equipment to achieve automatic control, save manpower and material resources. Second, is to monitor metal ( High temperature heating surface, the generator core, line sha-lu, etc. ) Temperature and temperature difference, prevent the creep of metal overheating, loss of mechanical strength, prevent generator, transformer insulation damage bars, etc. , so, in this case, the position of thermometer in the power plant is the leader of the flock. Is the most commonly used in power plants with contact bimetallic thermometer, it not only has instructions, still have available for the part of signal 帯, junction box is thermocouple thermal electrode and wire connection device, seal and protect the hot electrode in addition. Also is used in power plants, bimetallic thermometer, it will be made according to the need to set type axial and radial type, universal type, in order to adapt to the needs of practical production, bimetallic thermometer has different installation fixed form: movable external thread pipe joint, movable threaded pipe joints, fixed nipple, card sets of nipple, flange joint and a fixed flange, etc.
