OVERVIEW
AT9000 Advanced Transmitter is a micropro-
cessor-based smart transmitter that features high
performance and excellent stability. Capable of
measuring gas, liquid, and vapor, and liquid lev-
els, it transmits 4 to 20 mA DC analog and digi-
tal signals according to the measured differential
pressure.
It can also execute two-way communications
between the communicator, thus facilitating self-
diagnosis, range resetting, and automatic zero
adjustment.
