AT9000 Advanced Transmitters are smart differential pressure and pressure transmitters equipped with microprocessors for high performance and reliability. They can measure flow rate, pressure, and fluid levels of gases, liquids, and steam, as well as transmitting 4–20 mA DC analogue or digital signals in proportion to the measured pressure. By means of two-way communication between the AT9000 and a CommStaff or HART® communicator, operations such as self-diagnosis, range setting, and zero adjustment can be easily accomplished.
