P1A family features a highly modular compact geometry. This modularity and extensive range of options offered
by the P1A family make the advantages of Ceramic Capacitive technology in low-pressure sensing now
available to the broadest spectrum of industrial applications. Besides the multiple standard configurations
available, customized adaptations can also be considered.
Kavlico’s P1A Ceramic Capacitive Pressure Sensor incorporates the latest generation sensing elements
with state-of-the-art ASICs. Designed to withstand harsh environments, it features superior EMI protection,
outstanding shock and vibration performance, impressive longevity and lifetime performance and high quality. It
is tested to parameters that match or exceed those of competing products on the market.
