Fixed number of year of the bimetallic thermometer inspection and process

As everybody knows, bimetallic thermometer, pressure gauge, such as instrument, in the country's relevant legal provisions are need to inspection, the general chemical enterprises are commonly used for a period of test time of the bimetallic thermometer how long? First you need to know in one chemical enterprise, general inspection process: responsible for the measurement of the relevant departments, the system construction period need to classify all within an enterprise to use measuring instruments; General enterprises are divided into three categories: a kind of measuring instruments, the state compulsory verification of measuring instruments, enterprise traceability standard measuring instruments, measuring instruments used in trade settlement, safety, environmental protection of the measuring instruments, involves the security key measuring point of the measuring instruments, the specific risks such as toxic, flammable warning device, such as high temperature and high pressure equipment testing point measuring instruments, measuring instruments must be divided into level outside the mandatory inspection, no special requirements of component verification period is 1 year commonly, on the pressure gauge, bimetallic thermometer for half a year; 2 kinds of measuring instruments, general and manufacturability of all measuring instruments, including temperature, flow stress level enterprise standard, and so on, this kind of measuring instruments calibration cycle is usually for one year or two years; Three types of measuring instruments, the enterprise in the use of the key parts of the measuring instruments, some only need to do the first inspection, after some cycles can drag. Division of measuring instruments must be at the highest level of judges, meeting minutes and evaluation conclusion, please state institutions and technical supervision department or security department related personnel to attend, will make your judges has more legal benefits. According to the chemical standards, the second class the following measuring instruments calibration cycle can be adjusted according to the actual situation of production, issued general adjustment efforts in time and state of the time difference in the gage verification directory cannot too big, such as the verification cycle can be adjusted for a chemical enterprises overhaul cycle, or if you don't often use, not easy to damage the components can be changed from one year to two years. If it is a security check, the above said a kind of measuring instruments calibration interval parameter and calibration certificate, are inspected content; Second is generally enterprises themselves for the record, parameter records, and then by the technical supervision inspection. In accordance with the above requirements, bimetallic thermometer using the enterprise, to be in the specified process conditions, once every half a year to check the calibration, to ensure the normal use, of course, can be adjusted according to actual condition for a year or two years.
