3.5 Oil Temperature Sensor Pt 100
The temperature of the oil is influenced by the load on the pump, the ambient
temperature and the cleanness of the oil cooler.
The temperature of the oil may be measured by the system controller using
the standard temperature sensor Pt 100 and the SP-Guard. The Pt 100
measures the temperature of the oil downstream of the oil cooler.
The oil temperature must not exceed 70 °C.
At an oil temperature of 60 °C, the SP-Guard indicates a warning message.
This message can be used for checks on a regular basis.
At an oil temperature of 70 °C, an error message is output.
If the temperature of the oil deviates during normal loads and ambient con-
ditions from the process dependent standard values, the oil cooler should
be checked to see if it has accumulated any dirt.
