Data
 
   
 
The pressure transmitters of the 33X series use digital compensation with a mathematical model to achieve exceptional accuracy of 0,05 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. Additional measurements and selections can optionally be used to achieve a precision (and also, if calibrated in an accredited test laboratory, an accuracy) of 0,01 %FS. In addition to the digital RS485 interface, the X-line transmitters have a rangeable, analog current or voltage output.
 
Features 
  • Maximum accuracy/precision down to 0,01 %FS
  • RS485 interface can be combined with analog interface
  • Analog interface rangeable by RS485 interface (turn-down)
  • Modbus RTU protocol for process values and configuration
  • Highest long-term stability
