INTRODUCTION
The ber optic thermometer FOTEMP1 is ideal
for the use in EMI, RFI, microwave and high
voltage environments. It combines innovative
design with user-friendly functionality. The new
ber-optic thermometer FOTEMP1 combines
innovative design with user-friendly functiona-
lity. The modern design makes the temperature
measurement even easier and oers complete
immunity to RFI, EMI, NMR and microwave
radiation.
The FOTEMP1 has an innovative appearance:
It has a larger screen and a modern keyboard
which makes the data acquisition and control of
the device even easier. The user-friendly display
supports high-precision measurements, while
the color LCD display oers excellent readout
of the measurement values even in low light
conditions. The menu
supports two languages,
German and English.
With its compact design,
it ts perfectly into any
environments. Various
interfaces, analog and relay
outputs make the device very
versatile. The extensive software„Fotemp Assis-
tent“ allows a detailed evaluation via PC with
direct export of data to an Excel spreadsheet.
The FOTEMP1 has a measuring range from
-200°C to +300°C. It measures with the usual
Optocon accuracy of ± 0.2°C. The ber optic
thermometer oers complete immunity to RFI,
EMI and microwave radiation, making it ideal
for environments where the use of conventi-
onal temperature measuring instruments is
excluded due to extreme conditions.
It is compatible with all our ber optic tempera-
ture sensors and is ideal for any applications in
the laboratory and in industry.

USER MANUALFOTEMP1 7
The outer jacket of the ber optic temperature
sensors is made out of teon, at the sensor tip a
GaAscrystal (gallium arsenide) is attached. The
probe sensor is completely non-conductive.
Optocon’s ber optic sensors oer complete
immunity to RF and microwave radiation with
high temperature operating capability, intrinsic
safety, and non-invasive use. The probes are
also designed to withstand harsh and corrosive
environments.
Starting at a light wave length of 850nm GaAs
becomes optical translucent. Since the position
of the band gap is temperature dependent, it
shifts about 0.4nm/Kelvin.
The measurement device contains a light sour-
ce and a device for the spectral detection of the
band gap. This guaranties fast, repeatable and
reproducible measurements.
Via the analog outputs and thanks to its
accompanying software“FOTEMP-Assistant”,
measurement results can be easily controlled
and monitored.
Over the entire life of the system calibration is
not required to remain within the specications.
