Booth 509
June 24-26, 2025 | Santa Clara Convention Center | Santa Clara, California
At Sensors Converge 2025, we’ll be showcasing our latest MEMS-based anemometer sensors designed for airspeed monitoring in HVAC and airflow applications, alongside solutions for refrigerant leak detection and vacuum sensing
PAV5000 Series MEMS Anemometer Sensor
Fully calibrated and temperature-compensated for easy integration into portable anemometers and fixed in-duct air velocity monitors, the cost-effective PAV5000 series sensor provides accurate air speed measurement in a robust, probe-style package. While traditional thermistor-based anemometer sensors connect to the circuit via a thin thread, the PAV5000’s sensing element consists of a solid silicon chip flush-mounted onto a PCB, making it robust against damage caused by vibration, dropping, or collisions.

PGS6032-R and PGS6454-R MEMS A2L Refrigerant Leak Sensors
The PGS6032-R and PGS6454-R sensors have been recognized by UL Solutions. This distinction verifies that the devices meet the safety and performance requirements for refrigerant detection systems outlined in Annex LL of UL 60335-2-40:2022, fourth edition, which apply to household and similar electrical appliances, including heat pumps, air conditioners, and dehumidifiers. The PGS6000 series sensors accurately detect A2L refrigerant concentration in the air by measuring the change in thermal conductivity of the gas mixture inside the cabinet. This technology increases safety and efficiency by enabling early detection of leaks, while providing long-term reliability of 15 years or more in harsh environments.

PVC6800 Series MEMS Pirani Gauges
PVC6800 series Pirani gauges deliver high accuracy and long-term stability for ATM to medium vacuum applications. By incorporating the sensing element and digital electronics within an individually calibrated probe, Posifa’s vacuum gauges eliminate the need for calibration of replacement probes, minimizing the total cost of ownership. The devices can be customized to emulate output voltages from other manufacturers’ gauges, allowing for easy plug-and-play replacements without the need for software or hardware changes.

MEMS Pirani Vacuum Transducers
PVC4000-C series and fully calibrated PVC5800 series Pirani vacuum transducers are ideal for digital vacuum gauges and leak detection in vacuum-insulated panels. Designed for cost-effective OEM integration, the devices consist of a surface-mount MEMS Pirani sensor and microcontroller-based measuring electronics — all packaged in an ultra-compact PCB assembly featuring a connector-terminated wire harness.
