ABB P 266CSH CST 266JSH JST

Overview 266CSH/CST

The multivariable transmitters in the 266CSH are used for differential pressure flow measurements. Apart from pressure- and / or temperature-dependent changes to the density of the fluid, the parameters such as the discharge coefficient, thermal expansion of pipelines and primary device and the Reynolds number are also corrected. It can also be used for DP level measurement if density compensation is necessary due to process temperature changes. This could make any level measurement much more reliable.In addition to high precision, the multivariable 266 also offers the advantage that only a single device needs to be used for the measuring point instead of several transmitters and a flow calculator.

Data 266CSH/CST

  • Base accuracy: ± 0.075 %
  • Reduced process penetrations save money and reduce the risk of leakage
  • High static working pressure option (41 MPa, 6000 psi) for power plants, pipelines or oil and gas production
  • True draft range (down to 0.05 kPa, 0.2i nH2O) transmitter
  • Local operation with LCD with TTG (Through The Glass) technology without the need of opening the housing
  • Detection of plugged impulse lines
  • Integrated totalizers and in addition a binary output as pulse or frequency output for activating external totalizers
  • Exchangeable electronics with automatic configuration capability

Overview 266JSH/JST

Reliably providing the most accurate measurement of DP, SP, temperature, and diagnostics every single second

The 266 Modbus® multivariable provides precise and reliable measurement of differential pressure, static pressure, temperature (from an external RTD) and diagnostic information once every second, to flow computers and RTUs. Individual device Modbus® addresses can easily be configured using the optional keypad/display or using the XMV Interface application in ABB’s Totalflow flow computers or RTUs. This application creates a “plug and play” interface to the multivariable sensor and indicates any active alarms that may be present in easily understood text. The combination of ABB’s Totalflow flow computer or RTU and one or more ABB 266 Modbus® multivariables makes an ideal solution when multi-tube measurement is required and/ or when the transmitters must be located in a Class I, Division 1 hazardous location.
