Thermopile is usually a blackened thermal detector .
热堆一般是个涂黑了的热探测器。
The surface high temperature measurement technology based on mems thermopile sensor .
基于mems热电堆的表面高温测试技术研究。
This instrument is factory calibrated to a nist ( national institute of standards and technology ) traceable thermopile and should require no field adjustment .
这仪器是由工厂校准的可追踪热电堆，符合nist要求，出厂后不需要再做调整。
These thermocouples are connected electrically , forming an array of multiple thermocouples ( thermopile ) . They are then sandwiched between two thin ceramic wafers .
