Description

Stratos Pro A201 COND Conductivity Transmitter | Analog Sensors | Ex Zone 0/1 | HART | 2x 4 ... 20 mA Outputs

2-wire analyzer for conductivity measurement

  • Explosion protection: Zone 1 / Class 1 Division 1 (with sensor in Zone)
  • Digital communication: HART 
  • Two current outputs
  • 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. 
 
Zone 1 Explosion Protection
Stratos Pro is designed for operation in Zone 1 / Class 1 Division 1 hazardous areas (with the sensor in Zone 0). Operation in hazardous areas from –20 °C to +65 °C is possible. The devices are designed for gas and dust explosion protection (G/D) and can naturally also be used outdoors (type 4 enclosure, UV resistant).

We look forward to hearing from you!

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.
