Differential Pressure Transmitters (Model JTD9_ _ _) can measure flow rate, pressure, and fluid levels of gases, liquids, and steam, as well as transmitting 4–20 mA DC analog signals in proportion to the measured pressure.
By means of two-way communication between Model JTD9_ _ _ and a Model CFS100 or HART® communicator, operations such as self-diagnosis, range resetting, and zero adjustment can be easily accomplished.
