Oil Lubricated Vacuum Pumps U 4.70-630Overload protection by temperature control
Control unit
Sensor PT 100
optimum sensor position in the pumphousing
is near the outletpump outlet
pump intake
to contactor
Advantages of housing temperature control
Safe detection of all kinds of overheating due to :
Lack of oil Clogged oil cooler Clogged oil separator Defective fan or contacting rotor High ambient temperatures
Oil Lubricated Vacuum Pumps U 4.70-630Overload protection by temperature control
Temperature sensor Pt 100
Advantages of Becker control unit
> two temperature limits are available
> first limit is intended for warning of operator to check the condition of the machine
> second limit is used to cut off the machine in order to prevend overload
