Dwyer Instruments has released the new Series LDT Leak/Over-Temperature Detection Relay.

The Series LDT Leak/Over-Temperature Detection Relay is used to monitor the shaft seal and the stator temp of a submersible pump to detect a leak or over-temperature before pump failure.

A leak is detected by sensing the status of a float or conductivity switch installed in the seal cavity. When this resistance drops below the set sensitivity, the output relay energises and the LED indicator illuminates.

When the seal failure condition clears, the relay automatically resets. A normally closed temperature switch mounted on the stator detects over-temperature. The temperature safety feature incorporates a bi-stable relay that retains its position during power loss and latches on until the remote reset button is pressed.

The LDT has adjustable leak sensitivity from 1 k to 35 k ohm. Installation is made simple with a surface mount configuration.

The Series LDT Leak/Over-Temperature Detection Relay is available from Dwyer Instruments.
