Description

The Seal Leak and High-Temperature Detector DFS-12 detects seal failure in submersible pumps equipped with these sensors. When water enters the seal, it mixes with the oil, and this moisture can be detected by the insulation level. If the leak is not detected in time, the moisture can cause insulation failure in the pump and burn it.

The DFS-12 also detects excessive heating of the pump through the temperature sensor and disconnects the pump to protect it from burning.

When the DFS-12 detects a problem, it opens an internal contact and turns off the pump. An indicator LED corresponding to the fault lights up. Reset can be adjusted to be manual or automatic. It has a fault memory that keeps the fault LED flashing until the memory is manually cleared.

Optional Equipment

• Adapter plate for DIN rail mounting
