Power supply connection
The supply circuit must be protected by a suitable protective device
Local regulations for electrical installation and safety must be
observed.

5.5 Sensor connection in general

If the temperature sensor is exposed to a corrosive or caustic environment, it must be
protected by suitable measures. The sensor must be positioned so that it shows the
actual process temperature:
1. in a liquid medium: in the area with the most movement
2. in air: in the area with the highest air circulation
If the sensors are inserted in pipes at some distance from the hea-
ting vessel, this leads to a thermal "transport" delay (gradient) and
thus to poor control behaviour.
