Absolute Pressure Transmitters
AT9000 Advanced Transmitter Absolute Pressure Transmitters (GTX**A series) are used to measure the absolute pressure of gases, liquids, and steam, as well as to monitor tank pressure. With their extremely wide measurement range (GTX60A: 35 to 3500 kPa, a rangeability of 1:100), they help to cut costs by reducing the number of spare units required.
