Product Overview
Combined Insulation Resistance and Seal Oil Monitoring Device Sari 2 Grundfos 96061602 Sari2
The Grundfos SARI 2 is a combined monitoring device for motor insulation resistance and seal oil water content. The motor insulation resistance is measured between one of the mains phases and ground when the pump is stopped and disconnected from the mains supply. Low insulation resistance indicates moisture inside the motor. which could lead to the motor burning out and expensive repair work.
In the case of a pump equipped with a Grundfos OCT 1 oil condition transmitter. the SARI 2 also continuously monitors the water content in the seal oil chamber. As the primary shaft seal wears in time and water leaks into the oil chamber. the OCT 1 probe indicates the water content in the seal oil. This information is routed to the SARI 2 monitoring device. which raises an alarm
