Stratos Pro
2-wire transmitters providing comprehensive features
Stratos Pro offers pioneering solutions for analysis of pH, ORP, conductivity (conductive or inductive) and oxygen using 2-wire technology.
- Intuitive operation with color-coded user guidance
- For digital Memosens and analog sensors
- Extensive diagnostic functions with Memosens sensors
- IP 67/NEMA 4X protection
- Explosion protection: Zone 1 / Class 1 Division 1 (with sensor in Zone 0).
- Digital communication:
- PROFIBUS-PA
- FOUNDATION-Fieldbus
- HART
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. $$$sSLIDEOUT$$$
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).
