Rostec's RosEl Delivers First Batch of Vulkan Magnetic Contact Sensors

RosEl Holding Company (RosEl), a subsidiary of Rostec, has delivered the first batch of Vulkan magnetic contact sensors to customers. The product is designed for high-pressure steam pipeline applications and can be used in automation and signaling systems, including those at nuclear power plants.

According to reports, Vulkan sensors are installed inside steam pipeline valves and are primarily used to monitor and control the valve closing process. The device can operate at temperatures up to 350 degrees Celsius, withstand mechanical shock acceleration of 150g, and achieve seismic category 1 rating, maintaining operational capability under strong earthquake conditions.

The sensor features a stainless steel housing and has a design service life of up to 12 years. Its core reed switch requires no external power supply, is smaller than traditional Hall effect sensors, offers high reliability, and has a design actuation count of up to 5 billion cycles.

RosEl stated that the adoption of its R&D achievements by Russian enterprises reflects the value of the relevant products in strategic industries. Vulkan sensors have been adopted by a major Russian pipeline valve manufacturer for use in the natural gas, oil, and nuclear energy industries, and can also serve the electric power and railway engineering sectors.

Reed switches are a widely used class of basic components applicable in fields such as household appliances, automotive, medical, telecommunications, and security systems. In end-use equipment, these components typically serve as contact assemblies for various types of switches.
