The FTL325N is a vibronic point level detection switch designed for liquid tanks, including those in hazardous explosion areas. It functions as a switching unit suitable for overfill prevention, pump protection, and overflow detection. The device is mounted on a DIN rail with a housing width of approximately 22.5mm and features multiple channels—typically up to three—each equipped with SPDT and SPST contacts for level and alarm signaling. It operates within a voltage range of approximately 20-30VAC or 20-60VDC, depending on the configuration. The FTL325N complies with safety standards for hazardous locations, such as Zone 0 or Zone 20, and is designed for reliable operation in demanding environments.
