2-wire oxygen sensor

current output4-20 mAlong-life

Description
This sensor, very robust and with low long-term drift, enables both presence detection and precise measurement of oxygen (O₂) concentration. It is designed for air quality monitoring and personnel protection.

Applications and main functions

• O₂ transmitter for ambient air monitoring in nitrogen tank storage areas
• Measurement of oxygen concentration in % vol
• Compliant with the ATEX directive and current toxicological standards
• Compatible with Nano SPY U and LoRa SPY U data loggers

Safety
The transmitter ensures compliant and secure monitoring of the atmosphere in areas exposed to nitrogen-related risks thanks to its ATEX compatibility.
