Gauge Pressure Transmitters
AT9000 Advanced Transmitter Gauge Pressure Transmitters (GTX**G series) are used to measure the pressure of gases, liquids, and steam, as well as to measure tank pressure and fluid levels. They achieve high accuracy of ±0.04 % and long-term reliability (zero drift of only ±0.1 % over 10 years), greatly reducing calibration work after installation. With their very wide measurement range (GTX60G: 35 to 3500 kPa, a rangeability of 1:100), they help to cut costs by reducing the number of devices needed.
