Luxtron M-900 Fiber Optic Temperature Converter


Fiber Optic Temperature Sensing for Medical and Semiconductor OEMs Between -100 to 330ºC

The Luxtron M900 series FluorOptic® Thermometry (FOT) solutions comprise fiber-optic temperature sensors designed to provide precise and repeatable in-situ temperature measurements for control of processes involving RF, EMI, magnetic fields, and high voltages. OEM solutions m920 for semiconductor fab applications and m924 for medical MRI and implantable device testing, comprise an electronics assembly module and probes purchased separately. The m924 utility is a board well suited to fiber-optic transformer winding hotspot and temperature monitoring. All model options offer communication via ASCII (RS232) and Modbus (RS485) with the model range offering a choice between module and board form factors, and two and four channels. All systems feature built-in calibration tables for Advanced Energy’s probes to achieve accuracies as high as ±0.1 °C.
