ST AT-FLG Flanged Differential Pressure Transmitter

ST AT FLANGED DIFFERENTIAL PRESSURE
TRANSMITTER

ST AT Flange Type of Differential Pressure Transmitter

Advanced Transmitter is a microprocessor-based smart transmitter that features high performance and excellent stability. Capable of measuring gas, liquid, vapor, and liquid levels, it transmits 4 to 20 mA DC analog and digital signals according to the measured differential pressure.

It can also execute two-way communications between the Smart Communicator or HART® 375 communicator, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment.
