Torque Tube, Displacement Type Level Transmitter (SDT-420)

Introduction:

• The SEOJIN INSTECH model SDT-420 Displacement Level Transmitter is one of the most advanced level instruments based on displacer device.
  The buoyancy principle has been well known for many decades as its high reliability and stability.
  The SDT-420 operates under extremely harsh environment of 200kgf/cm2 of pressure and 450°C.
  Also interface measurement between two different liquids is possible.
  The buoyancy principle of Archimedes is applied into its operation. The SDT-420 can be configured parameter values and monitored the measured values by using PC ( SIEMENS PDM S/W) or HART Communicator in Control Center where located far distance from site. It is also possible to be adjustment, operation, and control easily by using conventional remote keypad on site.

Features:

• Possible to communicate with HART or SIEMENS PDM.
  
• Measurement range : 300~5,000mm.
  
• Process temperature : Wetted parts -40 ~ 450°C
  
• Process pressure : 200 f/cm2
  
• Output signal : 2-Wire type 4~20mA, HART, LCD.
  
• Range of specific gravity : 0.5~1.5.
  
• Allowable error : ±0.5% of the Full Scale
  
• Possible to actuate general functions by means of using remote keypad on site.
  
• Installation the continuity of process and self-diagnosis function.
  
• Displaying with the units of %, mm, inch, mA, °C and other physical units on site.
  
• Possible to compensate on site by inputting the conventional values of density, temperature, and of measurement distant of process, without acquiring the real value in site.
• Designed to ASME B31.1
  
• Weather proof
  
• Explosion-proof & Frame-proof
  
• Weld procedures approved to KEPIC MQ and ASME IX
  
• Material certification to ASTM, ASME, JIS, KS Standards
