Industrial SAL1810000EA01DU Admittance Point Level Sensor

AFINE SAL1810000EA01DU Admittance Point Level Sensor is a RF admittance point level switch designed to detect the presence or absence of process material at a fixed location in a vessel. It features a 1" NPT process connection and a rugged enclosure rated Type 4X, suitable for harsh indoor or washdown environments. The SAL1810000EA01DU is part of AFINE’s SAL Series of RF admittance sensors, which monitor the electromagnetic admittance between the active probe and the grounded vessel wall. When material fills the probe region, the admittance changes and a defined switch point is reached, signaling material presence or absence to the control system. The sensor includes a guard section that is energized with the same RF signal as the active probe to improve immunity to material build-up along the vessel wall, increasing reliability with sticky or cohesive materials. Typical applications include monitoring powders, granules, pellets, and slurries, as well as liquids, in storage tanks, hoppers, and processing vessels where a single-point level decision is required for control, overfill protection, or dry-run protection. Installation follows standard practices for RF admittance devices, with electrical connections made to compatible control circuits and proper grounding. The 4X enclosure rating and 1" NPT connection denote compatibility with common industrial installations, while the model designation SAL1810000EA01DU identifies the exact AFINE part for ordering and replacement within the SAL Series family.
