What are the typical features of universal type thermometer and use requirements

Universal type thermometer is used for measuring liquid, steam, gas in low temperature environment temperature, the main components by a use two or more pieces of metal laminate composed of multilayer metal together. Can real-time measuring temperature instrument, in order to improve the temperature measuring sensitivity, is usually metal on the thermometer from the design principle and structure of a waterproof, corrosion resistance, vibration resistance, intuitive, easy reading, no mercury pollution, strong and durable, etc. Universal type thermometer mainly has the advantages of quickly and accurately measure the speed, stable performance, adjustable Angle, higher overall small convenient measurement. Generally used in low temperature thermometer, thermocouple used in high temperature. If the temperature has been more than 500 ℃, could affect the measurement result, can appear even cannot come out measurements. So in type selection of universal time, temperature must be according to the need to detect temperature of the surrounding environment and timing requirements, such as the dial diameter, precision grade, insert depth, type and temperature range measured medium, etc. In addition, also attaches great importance to the performance and maintenance workload and other factors. In addition, it is important to note that in the transport, installation, use of universal type thermometer and a series of process should avoid collision sheath maerial of temperature, in order to ensure the precision of measurement, sheath maerial of insertion of the measured medium length should be not less than two-thirds of the length of the sheath maerial, banned twist instrument shell when installation, application of hexagonal wrench to adjust back.
