Absolute pressure transmitters measure system pressure against a reference vacuum rather than ambient pressure. Also known as pressure transducers, these instruments have a threaded process connection that secures them to an industrial process; their electrical connections transmit or send output signals to a control panel or monitoring system. They’re built with 316 stainless steel wetted parts for broad liquid and gas compatibility, and their NEMA 4X housings help protect them from harsh and outdoor environments. They’re commonly used in research and laboratory applications, food packaging applications, irrigation, pump control, and booster stations in liquid and gas pipelines.
