Rotary Paddle Level Switch

Rotary paddle level switch SITRANS LPS200 offers rugged construction, advanced safety technology and paddle options for precise, reliable level detection.

SITRANS LT500 is an advanced level, flow, and pump controller that works with radar and ultrasonic transmitters and any 2-wire 4–20 mA device, offering multiple options.

The SITRANS LPS200 rotary paddle level switch delivers reliable point level detection for bulk solids in harsh industrial environments. Its rugged design, advanced safety options and wide range of paddles, extensions and process connections help ensure dependable performance across extreme temperatures, varying material densities and demanding applications.

Accurately detects bulk solids in challenging environments, including high temperatures, dust, buildup and varying material densities. Designed for long‑term performance with minimal unplanned downtime.

A friction clutch protects the motor from damage, while automatic motor shutoff during alarms reduces wear. Five points ingress protection further extends service life in abrasive or dirty processes.

Multiple paddle styles, rigid or cable extensions, and rotatable enclosures allow easy adaptation to diverse installations, material types and mounting orientations without complex customization.

–25 to 600°C (–13 to 1112°F), higher temperatures upon request

Starting at 15 g/l (0.9 lb/ft3) with optional vane

Compact, rigid extended, cable extended, angle extended

Functional safety (SIL 2), device suitable for use in accordance with IEC 61508 and IEC 61511; fail-safe configuration; high-temperature model; extension kit (cable or rigid); universal power supply

Optional SIL2-certified configurations, pulse-sense rotation monitoring, and fail‑safe operation provide enhanced protection for personnel and equipment. These features help detect rotation failures early and support compliance in safety‑critical bulk solids applications.

Built to withstand temperatures above 600 °C and demanding solid materials, SITRANS LPS200 offers robust construction and five points of ingress protection. It performs reliably in silos, bins and hoppers with heavy buildup or abrasive media.

Field‑mountable electronics, a rotatable enclosure and easily replaceable paddles simplify installation and servicing. Hinged vane options and compact process connections support low‑density materials and space‑constrained installations.

Designed for demanding bulk solids applications, the SITRANS LPS200 rotary paddle switch delivers reliable point level detection, SIL2 safety options and rugged performance to support safer, more resilient cement plant operations.

The SITRANS LPS200 enables reliable high‑ and low‑level detection for fine powders and bulk solids, delivering long‑term performance, reduced maintenance and dependable automation in continuous processing applications.

The SITRANS LPS200 is engineered for demanding environments with dust, buildup, vibration and extreme temperatures. A friction clutch protects the motor from damage, five points of ingress protection enhance durability, and motor shutoff during alarm conditions reduces wear and maintenance. SIL2 safety options are also available for critical applications.

The SITRANS LPS200 is widely used in cement, power generation, grain and milling, food processing, chemicals, and mining. It supports materials such as clinker, flour, sawdust, carbon black, ash, and other bulk solids — making it a versatile solution for both light powders and heavy, abrasive materials.

A properly engineered level measurement system should also include a level switch for alarm or backup purposes. Typically used for high-level overfill prevention and/or low-level dry-run protection, these safeguards help ensure safe operation and process reliability.

Supplementary components are designed to work in conjunction with most types of instrumentation to enhance functionality, such as by enabling remote displays and remote monitoring solutions. They help expand system visibility and accessibility.
