目前,从事热工计量的人员对如何合理确定测温仪表,如:电子电位差计、动圈仪表和工业用热电偶等的检定周期(指使用单位内部规定的检定周期,下同)重视不够,往往造成因测温仪表的故障而报废产品,或者因检定周期选择不当致使人力和财力浪费。在此,介绍测温仪表检定周期合理确定的主要原则和方法。首先,应对被检定仪表的稳定性和可靠性进行考察,只有在该仪表的两项性能指标均好的情况下再按下述方法合理确定检定周期。
At present, the staff engaged in thermal measurement of how to properly determine the temperature measuring instruments, such as: electronic potentiometer, moving coil instrument and industrial thermocouple test cycle (refer to the internal use of the unit test cycle, the same below) not enough attention , Often resulting in failure due to temperature measurement instruments and scrapped products, or due to the improper selection of test cycles resulted in human and financial waste. Here, introduce the main principles and methods of temperature measurement instrumentation cycle is reasonable. First of all, the stability and reliability of the inspected instrument should be investigated. Only when the two performance indexes of the instrument are good, the test period can be reasonably determined as follows.
