System Description: the fluorescent optical fiber temperature measurement system consists of four parts: fluorescent temperature demodulator (dt-501f), optical fiber sensor probe (dt-s100), fluorescent optical fiber temperature measurement host (dt-501m) and system management software. Among them: the optical fiber sensor probe (dt-s100) converts the temperature information of the detection position into the optical signal; the fluorescent optical fiber temperature demodulator (dt-501f) receives the optical signal with the temperature information sent by the optical fiber sensor probe in real time, demodulates it into the temperature value, and realizes the temperature measurement of the detected part; the fluorescent optical fiber temperature measurement host (dt-501m) connects multiple fluorescence through the RS485 bus way The optical fiber temperature demodulator collects the temperature information, over temperature alarm information and system status information, and transmits them to the system management software through Ethernet; the system management software controls and displays the relevant temperature and data changes.
System features:
l Real time online monitoring: real time detection of temperature data, multi-channel and detection;
l Contact measurement: contact temperature detection, high temperature measurement accuracy, short response time;
l Set threshold: alarm threshold, linkage setting, each channel can set the threshold separately;
