Relay detects leaks and over-temperature conditions.July 17, 2008 -
Series LDT monitors shaft seal and stator temp of submersible pump to help prevent failure. When leak is detected, output relay energizes, and LED indicator illuminates. Relay automatically resets when seal failure condition clears. NC temperature switch, mounted on stator, detects over-temperature, and bi-stable relay retains its position during power loss and latches on until remote reset button is pressed. Leak sensitivity is adjustable from 1 k to 35 kW.

NEW! Series LDT Leak/Over-Temperature Detection Relay
Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, has just released the NEW SERIES LDT LEAK/OVER-TEMPERATURE DETECTION RELAY.
The Series LDT 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 energizes 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.
