Temperature and Pressure Monitoring at Chemical Plants

Las necesidades de las empresas petroquímicas son muy diversas. Para salir adelante en el mercado altamente competitivo de hoy, los productores se esfuerzan por mejorar la calidad y la productividad. Yokogawa ofrece soluciones a su medida para estas necesidades con base en su larga y amplia experiencia en este campo.

Las plantas químicas dependen de procesos de producción continua y por lotes, cada una de los cuales impone diferentes exigencias para un sistema de control. Un proceso continuo exige un sistema de control robusto y estable que no falle y provoque el cierre de una línea de producción, mientras que en un proceso por lotes el énfasis se centra en tener un sistema de control que permita una gran flexibilidad para realizar ajustes a fórmulas, procedimientos y otros elementos. Ambos tipos de sistemas necesitan ser administrados en el historial de calidad del producto disponible, así como tener la capacidad de ejecutar operaciones no rutinarias. Con el respaldo de su extenso portafolio de productos, un equipo de experimentados ingenieros en sistemas y una red global de ventas y servicio, Yokogawa ofrece una solución para cada proceso productivo.

The high performance wireless differential pressure transmitter EJX110B features a single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

Wireless diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure and pressure transmitters, they are connected to the transmitter using capillaries filled with fill fluid.

The high performance wireless flange mounted differential pressure transmitter EJX210B features a single crystal silicon resonant sensor and is suitable to measure levels of densities of solidifying or precipitating liquids.

The high performance wireless pressure transmitter EJX310B features a single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

The high performance wireless guage pressure transmitter EJX430B features a single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.

Wireless diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the differential pressure and pressure transmitters, they are connected to the transmitter using capillaries filled with fill fluid.

The high performance wireless absolute and gauge pressure transmitters EJX510B and EJX530B feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure.

The high performance wireless absolute and gauge pressure transmitters EJX510B and EJX530B feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure.

YFGW410 Field Wireless Management Station has system manager/security manager/gateway function based on ISA100.11a, and combining this with Field Wireless Access Point(YFGW510) and/or Field Wireless Media Converter(YFGW610) composes the field wireless system.

YFGW520 Field Wireless Access Poin has backbone router function based on ISA, and combining this with Field Wireless Management Station (YFGW410) and/or Field Wireless Media Converter (YFGW610) composes the field wireless system.

YFGW710 Field Wireless Integrated Gateway comply to the wireless communications standard ISA100.11a for industrial automation of International Society of Automation (ISA), and relays ISA100 Device data to the system via integrated backbone router. Single unit of YFGW710 has integrated functions of backbone router, system manager, security manage, and gateway.

The high performance temperature transmitter YTA510 accepts Thermocouple, RTD, ohms or DC mill volt inputs. The transmitters transmit not only process variables but also the setting parameters using wireless signal. The transmitters run on internal batteries, and the installation cost can be decreased since hard-wiring is not required. The communication is based on ISA100.11a protocol specifications.
