Yamatake launches the complete range of the new model pressure transmitter, AT9000 Advanced Transmitter Model GTX


- Delivers safety instrumentation of plants and the world's highest performance level -

Yamatake Corporation announced today that it has started the shipping the complete range of the new-model pressure transmitter, the AT9000 Advanced Transmitter model GTX (hereinafter the "AT9000 model GTX?), which is designed to improve the safety of plant operations and achieve the world's highest level of performance. The Company has positioned the AT9000 model GTX as a global strategic product, and will start the sale of this product in overseas markets prior to its release in the domestic market.

Yamatake launched the sale of the world's first smart pressure transmitter in 1983. This smart transmitter, which significantly reduced maintenance work and achieved long-term operational stability, has sold over one million units worldwide, and has gained widespread popularity among customers.

In recent years, safety instrumented systems designed in accordance with IEC61511 are being used mainly by petroleum, petrochemical and chemical plants as a means of improving the safety of operations. These safety instrumented systems require pressure transmitters designed based on IEC61508. The IEC61508 standard imposes strict requirements concerning various aspects of a product, including its concept design, such as whether or not the product is designed to ensure safety instrumentation, or whether its failure rate is sufficiently low. The AT9000 model GTX satisfies all these requirements, providing a means of improving safety instrumentation, which will grow in importance in the future.

The AT9000 model GTX makes it possible to achieve the highest level of performance in the world to meet various requirements for ensuring the safety and stability of plant operations. We adopted a new type of Piezo resistive pressure sensor developed by Yamatake in order to achieve long-term stability which the zero drift is ±0.1% for ten years. We have also succeeded in achieving a high level of accuracy (±0.04%) to contribute to stable plant operation. The new model, which is capable of high-speed response with a response time of less than 100 ms, can be used for various applications that were previously incompatible with transmitters equipped with micro-computers. requirements, providing a means of improving safety instrumentation, which will grow in importance in the future.
