PVC1000 Series Pirani Vacuum Sensor

PVC1000 Series Pirani Vacuum Sensor

The PVC1000 Series of MEMS Pirani Vacuum Sensors offer a breakthrough vacuum measurement solution that enhances miniaturization while delivering ultra-low power consumption, long lifetime, minimal field maintenance, and low cost. Based on the principal that the thermal conductivity of gases is proportional to pressure in the low vacuum range, the Posifa sensors measure minute changes in resistance to a heated element resulting from heat transfer to the surrounding gas.
