Description

Stratos Pro A231N Multiparameter Transmitter | Memosens/Analog Sensors | Foundation Fieldbus

2-wire analyzer (Foundation Fieldbus)

  • Digital communication: FOUNDATION-Fieldbus
  • Intuitive operation with color-coded user guidance
  • IP 66/67, NEMA 4X protection
  • Automatic sensor identification
  • Sensor diagnostic with wear indication, remaining lifetime, CIP/SIP counter and adaptive calibration timer
  • High-contrast widescreen display with colored backlighting
  • Protective pane made of safety glass
  • One analog input (4 ... 20 mA) e.g. for external pressure compensation
  • Two parameter sets
  • Two digital inputs: 
    • External HOLD activation
    • External switching between parameter set
  • Logbook (200 entries)
Outstanding properties
A number of outstanding technological properties make the Stratos Pro series the new benchmark for 2-wire analyzers. Colored screen backlighting has been implemented for the first time in this device class, with the lowest possible power consumption.
 
Wide Range of Functions
2 digital inputs are provided, as well as an analog input plus a second current output for another measured value. 

We look forward to hearing from you!

Used in Process or Applications

Cooling Tower Monitoring
In a wide range of industrial sectors, cooling towers are used to dissipate process heat from cooling circuits. Mineral deposits and corrosion reduce their efficiency and lead to premature wear on plant parts.
