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
The pyrometer should be mounted, where it is not unnecessarily exposed to smoke, heat or
steam. Contamination of the lens leads to a lower display of the measuring value. Therefore,
make sure, that the lens is always clean. The field of view of the pyrometer must remain free.
Any interference by objects can cause measurement errors.
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, an air purge must be installed to protect the pyrometer from contamination.
• The permissible operating temperature is 0 - 65 °C. At temperatures above 65 °C, a cooling
jacket 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. The pyrometer should be preferably installed at 90° to the measured object. The angle
should not be less than 45° from the vertical. The spot must be completely filled by the
measured object.
