Installation and initial operation
Preparation
The pyrometer position and the respectively adjustable parameters are determined from the application.
Concerning the pyrometer position, please take care of ambient temperature, atmospherical conditions and
potential occurrence of electromagnetic interferences. Furthermore, factor the cable conduit for the used
connecting cables of the pyrometer into your planning.
Ambient temperature
The ambient temperatures must not exceed the allowed operation temperature for the pyrometer: 0 °C to 70
°C. Fiber optic cables (optical head side) and optical head can be used in ambient temperatures up to 250
°C. Higher ambient temperatures can lead to falsifications of measured values or to damages of the device.
Atmospherical conditions
Smoke, dust, steam or other air contamination as well as contaminated optics are a problem for non-contact
temperature measurement. As the Pyrometer cannot receive the full infrared energy for an exact
measurement, measuring errors will be the result. An air purge unit (see chapter Accessories, on page 31)
can be helpful to avoid contamination of the lens. The required air volume is 60 to 100 l/min (4 to 6 m
3
/h) with
a pressure between 0.2 to 1.0 bar. Only oil-free and dust-free compressed air should be used.
Electromagnetic interferences
Any interferences beyond may affect proper functionality of the pyrometer!
To protect the device from electromagnetic interferences the following methods are recommended:

The device should be mounted as far as possible from potential sources of interferences, e.g.
machine parts with electrical motors, which may produce interference peaks.

Use shielded cables for all connections. Please select a cable from our accessories list, chapter
Accessories, on page 31.
Installation of the pyrometer
Location requirements
It is recommended to use the available fixed or adjustable mounting angles for mounting of the device.
Please refer chapter Accessories, on page 31.
Operating personal requirements
Qualified operating personnel should do the installation. Please follow the instruction in this manual when
installing the pyrometer.
Advice: We only recommend qualified personnel to operate the pyrometer. The Proxitron GmbH will not
cover damages caused by improper installation of non-qualified operating personnel.
Mechanical installation
The housing can be mounted via 2 screws (M4) with toothed lock washer (DIN 6797). If the mounting is
made on a grounded surface the pyrometer grounding is compounded; otherwise the grounding has to be
led additionally.
Please note : The grounding has to be made basically at the pyrometer housing. The shield connector of the
cable must not be used for grounding!
If there is a risk of a potential difference between optical head and pyrometer, the optical head and the fiber
optic cable have to be led isolated or an appropriate potential equalization has to be made. The fiber optics
cable itself must not be loaded with equalizing current.
