Opsens OTG-i220 fiber optic temperature sensor

Brand: Opsens

Origin: Canada

OTG-i220 是 Opsens Solutions 半导体 GaAs 晶体光纤温度传感器，外径仅 0.22mm，专为 IGBT/SiC 功率模块封装内部的结温（junction temperature）直接测量设计——可穿过灌胶（gel filled）模块把传感头贴到芯片表面。基于 GaAs 半导体带隙吸收原理：宽带光经解调仪入射到 GaAs 晶体，吸收边沿随温度漂移，实现全介质（全电隔离）真值温度测量。常规款 OTG-i220-2R 为双传感点（2R）伸缩（telescopic）结构，是功率电子应用最常用型号；EMI/RFI 完全免疫、无漂移、测量分辨率 ±0.01℃，响应时间毫秒级，与任意 Opsens 解调仪即插即用、免标定免 GF 系数。
