Dwyer Proximity PLS2 Rotary Paddle Level Switch for Dry Solids
Rotary paddle point level switch for powders or dry solids in silos, hoppers, or storage vessels. Insertion length 5.9" to 78.7". NEMA 4/IP66 aluminum electronics enclosure. SPDT microswitch output. For process temperatures to 176° F (80°C) and process pressures to 11.6 PSIG. For media with bulk densities as low as 6 Lb/Ft3 (96 Kg/m3). CE, FM approvals.
Dwyer Proximity's PLS2 is an electromechanical level switch with a rotating paddle measuring vane. It is designed for use in dry powder or bulk solids in mining, food and beverage applications, silos, and hoppers. The PLS2 is unaffected by the dielectric constant of the sensed material, so it can be used in place of capacitance level switches for applications where the dielectric constant is too low, where there are multiple materials in one vessel, and when material moisture content can change.
- Single or double-sided spring paddle
- Optional shaft extensions from 8.5" to 78.7"
