201-100-SLD

Single-Channel Seal-Leak Detector

UL listed when used in combination

with OT08PC socket only.

Description

The model 201-100-SLD is an 8-pin plug-in style seal-leak

detector to sense seal failures on submersible pumps. A

microcontroller-based relay that monitors the shaft seal of

a submersible pump motor. A resistive probe is installed in

the seal cavity. If water leaks into the pump, the resistance

measured by the probe decreases. When the resistance drops

below the sensitivity setpoint, the unit will trip and the relay

contacts will change state. The unit will automatically reset

when a fault is cleared.
