Disposal
Inoperable instruments must be disposed of in compliance with local regulations for electronic
materials.
4. Introduction
The InsuLogix® T FoTemp 1 channel-optical fiber thermometer is used for measuring
temperature in an environment with High electromagnetic interference, or with the presence of
high power microwave fields. It can also be used in places where measurement with an electric
temperature probe is not possible.
With the InsuLogix® T Fotemp1 handheld you are able to operate a comfortable and safe
temperature measurement, even in difficult situations, with an overwhelming aggregated system
accuracy of ± 0.2°c.
Fotemp1 handheld is a compact, user-friendly, and easy to operate instrument for many fields of
application, e.g.:
•medical engineering such as nuclear spin tomography
•high frequency heating processes
•microwave power heating processes
•electric motors
•generators and transformers
•aeronautical engineering
•chemistry and petro chemistry
The outer jacket of the fiber optic temperature sensors is made out of Teflon, at the sensor tip a
GaAs crystal (Gallium Arsenide) is attached. The probe sensor is completely non-conductive.
Weidmann’s fiber optic sensors offer 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. The measurement results can be
easily monitored via the analog outputs and “FoTemp-Assistant” software. Over the entire life of
the system calibration is not required to remain within the specifications.

6. Calibration
To ensure an accurate temperature measurement in critical areas, we offer a comprehensive
calibration service for our fiber optic temperature measurement instruments. Through our
modern labs and our qualified staff we can guarantee you a very accurate and fast calibration.
Within a few days you get your unit back and can start your fiber optic measurement projects.
For each calibrated measurement instrument by us, a full certificate of test results is supplied.
Your fiber optical thermometer comes factory calibrated.
An annual re-calibration is not necessary, except for internal company regulations. All
calibrations are performed at our factory. For each calibrated measurement instrument by us, a
full certificate of test results is supplied.
Your account manager is available Monday to Friday 8:30 to 17:00 personally by phone
[phone]. In addition, you are welcome to send an email message to tell us your
concern. We will get in touch with you as soon as possible.

7. Getting started
1. Plug the provided optical fiber temperature sensors to the ST-connector on the upper of the
instrument, where the ON/OFF switch in located.
2. Connect the provided RS-232 interface cable to the thermometer and a free serial port of the
pc or notebook.
3. Use the provided power supply to power up the system.
4. After powering and switching the thermometer on, temperature values will be displayed if
sensor‘s level is above 20% signal strength
5. The thermometer is ready for measurement.
Caution! The fiber optical thermometer only functions with Weidmann fiber optic temperature
sensors. Please do not use temperature sensors of other brands.
Please read the instructions for installing the fiber optic instrument carefully.
Sensor handling
The sensor consists of a ST-connector 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 16. A
forcible bending of the sensor leads to breakage of the fiber. In this case the sensor is damaged
and needs to be repaired / replaced.
Connection with PC
Before establishing the first connection, please check whether the InsuLogix T device is
connected to the power supply and the pc via the rs-232 cable respectively.
Connecting the probes
The temperature sensors are connected via the ST-connectors 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 fiber optical temperature probes can be connected.
Important: All channels and probes not in use must be protected with supplied dust caps.

To ensure accurate measurements and long life of the fiber optic sensors and instruments, it is
necessary to clean them regularly. More information about cleaning can be found in a later
chapter.
Testing the temperature probe
To test the functionality of the sensor, you can place the sensor into a test liquid, of which the
temperature is known (e.g. boiling water). The sensor will respond with the given temperature
within a few seconds.
If no temperature is displayed please re-install the software and check if the sensor has contact
to the measuring object
