The AT9000 advanced transmitter from Yamatake is a microprocessor-based smart transmitter that features high performance and good stability. Capable of measuring gas, liquid, vapour and liquid levels, it transmits 4-20 mA DC analog and digital signals according to the measured differential pressure.

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

The composite semiconductor sensors realise high accuracy up to 0.04% FS and a response within 100 m. Long-term stability is up to 0.1% of URL per decade.

A wide measuring range is available from a single model. This feature is highly effective for taking measurement over a wide range and reducing the need for inventory. Models GTX30D, 31D and 32D have a range of 0.5 to 100 kPa.

A wide range of models is available to meet user requirements. They include draft range differential pressure, standard differential pressure, high differential pressure, standard differential pressure/high static pressure and high differential pressure/high static pressure models

A variety of corrosion-resistant materials for wetted parts are also available.

Two-way communication using digital output facilitates self-diagnosis, range resetting, automatic zero adjustment and other operations. HART protocol communication is available as an option.

A full range of approvals is available from FM, ATEX, IECeX and NEPSI, such as Explosion Proof, Intrinsic Safety and Dustproof. IECeX approval is to Ex ia, Ex nL, Ex iaD, Ex tD. Other approvals include SIL2.
