Cooling water connection

At ambient temperatures of more than 40°C the pyrometer must be operated with the

associated cooling! The two connections for the connection of a cooling circuit are located

under the instrument (see

Fig. 77).

The following should be taken into account when connecting a cooling circuit:

 Flow rate at least 1 l/min

 Pressure: maximum 6 bar

 Coolant temperature 10 °C to 35 °C

Cold tap water is usually sufficient for cooling. It should not be so strongly cooled that

condensation develops on the instrument. Take into account the environmental conditions

(air temperature and humidity) with respect to the cooling.
