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 functionality. The modern design makes the temperature
measurement even easier and oers 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 oers 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 Assistent“ 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 oers complete immunity to RFI,
EMI and microwave radiation, making it ideal
for environments where the use of conventional temperature measuring instruments is
excluded due to extreme conditions.
It is compatible with all our ber optic temperature sensors and is ideal for any applications in
the laboratory and in industry.

The outer jacket of the ber optic temperature
sensors is made out of teon, at the sensor tip a
GaAscrystal (gallium arsenide) is attached. The
probe sensor is completely non-conductive.
Optocon’s ber optic sensors oer 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 source 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 specications.

GETTING STARTED
1. Plug the provided optical ber temperature
sensors to the ST-socket on the
backside of the instrument. Please make sure
that the sensor marked as K1 is connected to
ST-socket number 1. Sensor marked with K2
must be connected to ST-socket number 2 etc.
2. Connect the provided RS-232 interface cable
to the thermometer and a free serial port of the
PC or Notebook.
3. To power the thermometer please use the
provided power supply.
4. After powering and switching the thermome-
ter on, Iour company logo and temperature values will be displayed for the dierent channels.
5. Now the thermometer is ready for measure-
ment.
If no sensor is connected, the display will show
„ Sensor?“.
Caution! The ber optical thermometers
only function with Optocon ber optic temperature sensors. Please do not use temperature
sensors of other brands.
General installation guidelines
Please read the instructions for installing the
ber optic instrument carefully. Please note
especially the order of the instructions exactly.
Sensor handling
The sensor consists of a ST-plug at the end
and a gallium arsenide crystal at the tip of the
sensor. The crystal is sensitive and should not be
exposed to excessive mechanical stress.
Please Please note the information about the
bending radius of the sensor on page 17. A forcible bending of the sensor leads to breakage of
the ber. In this case the sensor is damaged and
Page 14

needs to be repaired / replaced.
Connection with PC:
Before establishing the rst connection, please
check whether the FOTEMP device is
connected to the power supply and the PC via
the RS-232 cable respectively.
Connection with sensors:
The temperature sensors are connected via the
ST-plugs to the BNC sockets at the back panel.
Please note to insert the plugs pushing slightly
against the spring pressure and to turn with a
clockwise rotation.
All ber optical temperature sensors of Optocon
AG can be connected.

SOFTWARE
Installation
The accompanying software “FoTempMKT”
establishes the connection to the FOTEMP
device, displays the measured temperatures
graphically and saves the temperature data into
a log le, if needed.
For installation simply copy the le „FOTEMPMKT.EXE“ to a local hard disk folder and start
the program.
Set up
Before establishing the rst connection, please
check whether the FOTEMP device is
connected to the power supply and the PC via
the RS232 cable respectively.
Furthermore the COM port and connection
settings should be set correctly (button
“Portsettings”), see page 22.
Press the“Connect“ button : the connected device should display a temperature value shortly.
If an error occurs during the measurement (e.g.
no sensor connected) the display will show
“Sensor?” and the LED will ash red light.

ONE POINT CALIBRATION
If a slight deviation between real and displayed
temperature is encountered, it is
possible to eliminate the temperature dierence by doing a one point calibration at a well
known temperature.
For doing so please click the right mouse
button on the temperature panel which shall
be adjusted. A context menu will appear. Please
select “one point calibration” and enter the real
temperature value and click “OK”.
The device should now display the correct
temperature.
One point calibration can be made undone at
any time selecting „reset calibration“
from the content menu.

CONNECTING FOTEMP DEVICE WITH PC VIA USB RS232 CABLE
The driver for the converter must be properly
installed according to request. Use the included
CD:
1) Insert converter in the USB port
2) Windows 7 and 8 most of converters used
their own drivers
3) For Windows XP on request insert the CD and
select the source „CD“ in the driver manager
4) The driver installation must end with the
message that the installation was successful
and the new hardware is ready to use
5) For control you can look up in Settings /
Control Panel / System / Hardware / Device
Manager / Ports (COM & LPT).
There the converter must be as „USB Serial
Port“, „USB Serial Converter“ etc. registered and
do not equipped with error marker (yellow
question mark).
6) Here you can also read the „COM Number“,
which is necessary for future communication
with the software.
Manual parameter settings for serial interfaces
The serial port parameters must be set manually if you use some special converter types. In
that case you have to open the Device Manager
under Ports (COM & LPT) for seeing the characteristics of the converter display (double- click
the converter-entry). In the „Port Settings“ must
be set for communication with FOTEMP devices
following values:
Baud rate: 57600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

ANALOG OUTPUT / LED
The device has an alanog output corresponding
to each temperature channel. They are located
beneath each ST socket as BNC socket.
The limits are set to 0°C and 300°C.
For temperatures outside of this range analog
output is set to the maximum value.
The temperatures are mapped to values
between 0-10V or 4-20mA. If no temperature
sensor is connected, the maximum value is
applied.
The maximum values for the analog output
can be also set via the accompanying software
„FOTEMP-MKT“. For doing so, please make a
right mouse click and choose „Set Analog Out“,
for each channel.
LED
The LED indicates the status of each channel. In
case of damage, sensor either defective or nonexistence, the LED ashes red.
In normal operation, sensor is available, measurements are carried out, it ashes green.
