PRODUCT DESCRIPTION

DISPLACEMENT TYPE LEVEL TRANSMITTER [SDT-420]
Product descriptions
 • For the safe and efficient operation of various high temperature and high pressure steam drums, boilers and reactors used in Firepower Plants, Glass & Cement Plants, Petrochemical Plants and Steel & Paper manufacturing Plants, close monitoring and controlling of the interface level between water and vapor is very important. As these steam drums are working under extremely high temperature and pressure conditions, the instruments related to measuring and controlling the level must be defect-free. Otherwise, minor defects may bring serious damages to the other equipments or financial losses.
 • However the industry had relied on the instruments like Sight Glass or Float Type Level switches and had experienced many troubles so the demand for the alternative instruments had increased. To respond to this market demand, Seojin committed to the development of Displacement Type Level Transmitter based on its experiences and know-how, and finally has succeeded in launching this model to the market. Our Displacement Type Level Transmitter can assure the reliable operation even under the harsh circumstance like 200㎏f/㎠ and 450℃. 
 • This Displacement Type Level Transmitter is designed for measuring not only the level of on liquid but also the interface level between two different liquids. Its operation is based on the buoyancy principles of Archimedes and it supports remote monitoring by the configuration with PC (With SIEMENS PDM Software) or Universal Hand Held Terminal (HART Field Communicator). This instrument also supports the conventional way of operation and control so the users can operate and control it using keypads at the field.
