Rosemount1 configuration

Configure Your Rosemount 2535 Vibrating Rod Solids Level Switch

Single vibrating rod solids point-level switch for fine-grained, powdery, and "caking" media in storage and process vessels. Simple rod design resists caking better than tuning forks (2521) for sticky materials. Suitable for hazardous and dusty environments. Maintenance-free, no field calibration required.

2535 Solids Level Switch (Vibrating Rod)

Vibrating-rod (single-tine) point-level switch for fine grains and powders — alternative to the tuning-fork 2511/2521 for media that bridge between fork tines. The single-rod geometry is harder to bridge, more reliable in clumpy or sticky powders. Operates up to 150°C. SST construction, suitable for hazardous and dusty environments. Best for fine powders prone to bridging, light solids, and any storage vessel where fork-style switches have given trouble.
