ENGIE: chip integration certified under live plant conditions
Industrial gas environments punish sensors. Interferents poison sensing layers, humidity shifts baselines, and laboratory calibration rarely survives contact with a real facility. This co-development addressed all three directly.
Custom anti-poison membrane
A membrane was formulated specifically for ENGIE's gas environment — blocking the interferents that would otherwise compromise accuracy, while keeping full sensitivity to the target analyte. Membrane tailoring is how selectivity is preserved without sacrificing the low detection limit that makes early warning possible.
Chip integrated into existing hardware
The chemiresistor chip — Battery Sense's core intellectual property — was designed to work directly inside ENGIE's existing product. There was no rip-and-replace: integration was built around their form factor and electrical interface, which is the same path OEMs take when embedding the sensor into battery modules and home storage products.
Calibrated and certified on site
Calibration ran against real process gases drawn from the facility rather than synthetic references, and final certification was conducted at the plant under live operating conditions, with detection demonstrated at an extremely low 15 ppm.
| Workstream | Approach | Outcome |
|---|---|---|
| Membrane | Custom anti-poison formulation for site-specific interferents | Selectivity preserved at full sensitivity |
| Integration | Chip designed into existing ENGIE device and interface | No rip-and-replace hardware change |
| Calibration | Real process gases from the facility | Field-representative accuracy |
| Certification | Conducted at the plant under live conditions | Detection demonstrated at 15 ppm |
