Absolute Pressure Transmitters

CEHART

AT9000 SuperAce Absolute Pressure Transmitters (JTA series) are used to measure the absolute pressure of gases, liquids, and steam, as well as for monitoring tank pressure. Thanks to their very wide measurement range (JTA940S: 35 to 3500 kPa, a rangeability of 1:100), they help to cut costs by reducing the amount of equipment required.
