Yamatake Corporation offer a 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 a high level of performance. AT9000 model GTX pressure transmitters are available from AMS Instrumentation and Calibration .
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, which are 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.
A new type of Piezo resistive pressure sensor is developed by Yamatake Corporation to achieve long-term stability for which the zero drift is ±0.1% for ten years. Yamatake Corporation also achieved 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.
