5190系列温度调节器是Fisher公司最近投产的一种气动基地式温度指示调节器。该调节器结构新颖,测量元件采用热电偶或在0℃时具有100Ω到200Ω阻值的三线铂电阻元件。在表内采用了气动发电机作为直流供电,不再外接电源供电,从而巧妙地把气动——电测结合起来,解决了气动基地式仪表的测温问题。在原理上采用电子测温原理,然后转换成气压信号输出,直接控制执行机构。这比过去采用温度变送器、电一气转换再加上基地式的指示调节要简化很多。其主要技术指标: 1.给定指示精度±0.4％; 测量指示精度±0.75％; The 5190 Series Thermostat is a pneumatic base temperature indicator regulator recently introduced by Fisher. The regulator has a novel structure with a thermocouple or a three-wire platinum resistance element with a resistance of 100 Ω to 200 Ω at 0 ° C. In the table using a pneumatic generator as a DC power supply, no external power supply, which cleverly combined pneumatic - electrical measurements to solve the problem of temperature measurement of the pneumatic base instrument. In principle, the principle of electronic temperature measurement, and then converted into pressure signal output, the direct control of the implementing agencies. This is much simpler than using temperature transmitters in the past, combined with electrical conversion and base-level adjustment. Its main technical indicators: 1. Given instructions accuracy of ± 0.4%; measurement accuracy ± 0.75% instructions;
