460-15-100-SLD工業(yè)自動化與控制的控制器-液體液位規(guī)格書PDF中文資料

Description

The 460-15-100-SLD is a seal-leak detector to sense seal failures

on submersible pumps. A microcontroller-based relay 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. Output relay logic

can be reversed by removing an external jumper. The unit will

automatically reset when a fault is cleared.

Features & Benefits

FEATURES BENEFITS

Unique probe

protection logic

Probes are protected from scale build up through

pulsed DC signal between the probes

Invertible relay logic Allows flexibility to be used in pump-up and

pump-down applications

LED status indicators Provides visual indication of the relay status

2 relay contacts Control independent loads on different circuits
