Anderson-Negele SL Dual-Diaphragm Level Sensor

The Anderson-Negele SL is an inventory-grade hydrostatic level transmitter delivering precise, stable, hygienic liquid-level measurement for food, beverage, dairy, and pharmaceutical applications. A patented dual-diaphragm design — with the atmospheric reference measured through an un-cloggable diaphragm — eliminates drift caused by condensation and guarantees superior accuracy with long-term stability.

The SL handles both conductive and non-conductive fluids, provides reliable inventory control plus overflow and run-dry protection, and meets the highest 3-A hygienic standards. One-touch calibration, quick-disconnect receptacles, and optional HART communication make setup fast, maintenance low, and integration into modern automation environments seamless.
