The PX2780 high accuracy barometric pressure transducers are designed for applications in industry and science where accuracy, fast dynamic response and long term stability are important. The sensor and electronics are packaged in a rugged stainless steel and polyester case. A removable 5-pin terminal strip makes fast and secure connections. A high accuracy ceramic sensor is coupled with a digital compensation circuit using a custom ASIC to assure consistent accuracy and reliability over a broad range of environmental conditions. There is also a sleep mode where the unit only draws 1 micro amp that allows almost instant turn on/ reading for remote applications
