The pyrometer must be protected against high voltage and strong electromagnetic fields.
Use a shielded cable. The shield must be connected with the connector housing.
Use a flyback diode when switching inductive loads.
Installation
1. Select a suitable location for the pyrometer. The following criteria must be observed:
• The lens and the field of view of the pyrometer must be free of dirt, smoke and steam.
Otherwise, the air purge PS 01/A must be installed to protect the pyrometer from contami-
nation.
• The permissible operating temperature is 0 - 65 ° C. At a temperature above 65 ° C, the
cooling jacket PK 01/B AF1 must be used. As cooling medium, air or water are possible.
2. Check that the lens is clean. Assemble the pyrometer in the provided bracket and align the
pyrometer to the measuring object. If necessary, check the cooling medium and the maxi-
mum operating temperature.
3. Turn on the power supply of the pyrometer.
4. The pyrometer uses the intensity of infrared radiation for non-contact temperature measure-
ments. It is necessary to configure the pyrometer to the respective emissivity coefficient of
the measuring object to obtain exact measuring results (see manual PR, chapter 13).
The emissivity coefficient is set via the IO-Link interface:
