  • Page 12: Introduction

    Introduction The FOT Lab Kit is a fiber optic thermometry system that allows users to measure temperature where conventional sensors fail. ® Luxtron’s unique technology, called Fluoroptic Thermometry (FOT), offers probes that are totally immune to electromagnetic interference (EMI) and of entirely non-metallic construction. These...

    Figure 1-1 FOT Lab Kit Instrument The FOT Lab Kit Instrument uses an RS-232 serial interface for command input and data output. The unit communicates at 9,600 bps using an 8-N-1 data format. In addition, it includes a 0-10 volt analog output for each measurement channel.

  • Page 14: System Overview

    (optional) Fluoroptic Sensor Luxtron Fluoroptic Probe Instrument The FOT Lab Kit Instrument is a four channel system that includes 0 to 10V analog outputs for each channel as well as an RS-232 interface. Probes Luxtron offers standard fiber optic probes for use with the FOT Lab Kit.
  • Page 15 Introduction such as thermocouples, RTDs and thermistors. Call a LUXTRON applications engineer to discuss development of a custom probe for your specific OEM application. To see examples of custom probes, visit LUXTRON’s website at www.luxtron.com. Accessories The most common accessory is a fiber optic extension. The extension allows flexible mounting or locating of the instrument with respect to the point of measurement.

  • Page 16: Fluoroptic Technology Overview

    Pulses of light transmitted down the fiber optic probe cause the sensor to be excited and fluoresce. The DSP-based electronics of the FOT Lab Kit Instrument detect and calculate the decay time of this fluorescence after each pulse. This decay time varies precisely with the temperature of the sensor, providing the basis for accurate temperature measurement.
