Solid-state sensor protects machinery from shocks

The AGLD Series Ground Fault Sensors (photo) keep machinery and operators safe from accidental shocks. They are designed to monitor large machines, to detect moisture ingress in water-delivery and treatment systems, and to ensure safety in heating processes. They feature a one-piece, solid-core design. The output relay will change state at any point between 5 and 100 mA, or between 80 and 950 mA, depending on the model. These sensors have a large LED display, which shows the precise trip point clearly in any light condition. A delay can be set to allow downstream protection to activate before the sensor, keeping the main circuit protection hot and equipment energized while smaller faults are cleared, says the manufacturer. Electromechanical relay output provides both normally open and normally closed contacts. These sensors are said to be compatible with most automation and control systems. — NK Technologies, San Jose, Calif.
