O2-G2 Oxygen Sensor (O2 Sensor) Description
Alphasense Oxygen sensors use capillary flow control.
Unlike partial pressure oxygen sensors, they have good pressure and
temperature dependence, making them the best choice in safety
applications.
Standard galavanic sensors use lead for greatest reliability but
fixed lifetime.
O2-G2 Oxygen Sensor size:
Miniature, proven long-term performance. The sensors are designed
for the next generation of portable gas detectors. Part of the
Alphasense ‘D‘ family.
O2-G2 Oxygen Sensor (O2 Sensor) Key Features & Benefits:
Small Footprint
Reduced Height
Low Weight
Good Connectivity: Uses industry standard, low cost, Molex sockets for direct board
insertion.
Reduced Costs: High quality design with a significant reduction in the cost per
measured gas, allied to reduced manufacturing costs are passed on
to OEMs
