Schreiber SM64 Series Redundant Angular LVDT
- Manufacturer: Schreiber Messtechnik
- Category: Displacement, LVDT, Angled LVDT, SENSORS
He angular LVDT The redundant Schreiber SM64 series represents the safety-critical standard in rotary measurement for extreme conditions. This device, technically classified as a dual-system inductive transducer, integrates two electrically isolated measuring channels in a massive 7 kg stainless steel housing. This architecture ensures a signal stability and EMI immunity absolute, allowing a 1:1 compatibility / drop-in replacement in naval rudder control systems, port cranes and port machinery where the failure of a sensor would paralyze the logistics operation.
Designed to withstand immersion and harsh saline environments with protection IP68, This angle transducer eliminates mechanical wear by lacking internal physical contact, ensuring an accuracy of 0.5% for millions of cycles. The SM64 is the ideal rotary position sensor for industrial installations requiring direct PLC redundancy, combining the ease of finding an "angular LVDT" with the robustness of heavy-duty, naval-grade armored German equipment. See here for the dimension diagram for mounting on an 80.0 mm flange.
