Luxtron Fiber Optic Thermometer
4-Channel Fluoroptic® Fiber Optic Temperature OEM Module

Luxtron fiber optic thermometer designed for use with Luxtron range of Fluoroptic® STB and STF fiber optic temperature probes. The m924 OEM Module is one board that contains four fiber optic temperature sensing channels, RS232 ASCII and RS485 Modbus digital output, and 5 to 24 VDC power input connection. The m924 board conditions the measurement signal from Fluoroptic® probes and reports a calibrated temperature to the OEM control system. The custom non-metallic probe sensors are safe in the harsh environments and connect to the m924 board via robust fiber optics.
