Product Overview
The System Sensor WFD20EXP is an explosion-proof waterflow detector for 2" pipe applications. Housed in a NEMA 4-rated cast aluminum enclosure, it operates indoors or outdoors from 32°F to 160°F. Two SPDT (Form C) synchronized switches in a durable terminal block provide reliable signaling. The spring mechanism is isolated from the explosion environment, and a sealed retard mechanism prevents contamination, ensuring consistent operation.
