一、装置的设计原理根据CJ128-2007《热量表》行业标准、JJG225-2001《热能表检定规程》和CJ/T188-2004《户用计量仪表数据传输技术条件》相关标准和检定规程中对温度传感器耐久性试验的要求,将配对温度传感器缓慢(1min至3min)插入已达上限温度的热量表温度传感器面耐久性试验装置(以下简称“试验装置”)中,并在该温度下保持足够的时间,然后(一般5min)再将温度传感器缓慢(1min至3min)插入已达下限温度的试验装置中,并在该温度下保持足够的时间,最后缓慢
First, the device design principles According to CJ128-2007 “heat meter” industry standards, JJG225-2001 “heat meter verification procedures” and CJ / T188-2004 “household measuring instruments data transmission technology,” the relevant standards and test procedures for temperature Sensor durability test requirements, the mating temperature sensor slowly (1min to 3min) has reached the ceiling temperature has reached the upper limit of the temperature sensor surface durability test device (hereinafter referred to as “test device”), and maintained at that temperature Sufficient time, then (usually 5min) and then the temperature sensor slowly (1min to 3min) inserted into the lower limit of the temperature of the test device, and maintain sufficient temperature at this time, and finally slow
