Posifa Technologies, Inc. products

Posifa Technologies announces its new PAV1000 series of air velocity sensors for data center thermal management and HVAC applications such as filter monitoring. Measuring air velocity at 7 m/s (PAV1005V) and 15 m/s (PAV1015V), the devices offer extremely fast response times of 125 ms typical in a compact, robust package. 

The PAV3000 series of air velocity sensors features a digital I²C output and a surface-mount footprint for thermal management and filter monitoring in even the most space-constrained locations.

PMF2000 features Posifa’s third-generation thermal flow die, benefiting from the latest innovations in microfabrication. The sensor die uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow, delivering excellent signal-to-noise, and repeatability. The “solid state” thermal isolation structure on the sensor die eliminates the need for surface cavity or fragile membrane used in competing technologies, making the sensor resistant to clogging and pressure shock. The PMF2000 series includes the analog output PMF2000V and the digital I²C output PMF2000D. The supported max flow rate ranges from 200 sccm to 10 SLM. The sensors are temperature compensated over the temperature range of 0 to 50 °C. The linearized output provides maximum flexibility and ease-of-use.

Posifa Technologies introduces the new PGS1000 series of MEMS thermal conductivity hydrogen sensors, designed for stable, cost-effective safety monitoring in environments where hydrogen is used and stored.

The PGS4100 series of hydrogen accurately detects hydrogen concentration in the air by measuring the change in thermal conductivity of the gas mixture. Used within battery management system (BMS) compartments, this technology enables faster reaction times for triggering battery failure alarms in electric vehicles (EVs), ensuring compliance with safety standards.
