LUXTRON Fiber Optic Temperature Sensors

4-Channel Fluoroptic® Fiber Optic Temperature OEM Module

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.

MRI, RF, R&D and OEM Applications

Suitable for medical magnetic resonance imaging (MRI) and radio frequency (RF) original equipment manufacturers (OEM), implantable medical device testing, and research and development Labs. It has +/-0.05 °C accuracy, up to a 50 Hz sampling rate/channel, and -100 to 330 °C temperature range.
