Los datos de flujo de gas calculados por una RTU pueden ser enviados a un transmisor utilizando la comunicación bidireccional del FOUNDATION fieldbus.

Operators must receive diagnostic information before a line block leads to a malfunction. Yokogawa provides predictive diagnostics based on trend analysis of the blocking factor, which improves maintenance efficiency and reduces maintenance costs.

La configuración del transmisor de nivel puede tomar mucho tiempo. Los transmisores DPharp tiene la función de un software avanzado eliminando esta tarea que toma tiempo. Con talleres de mantenimiento cada vez más pequeños, la búsqueda de equipos que nos permiten hacer más con menos se convierte en una prioridad.

Los controladores autónomos de nodo de control de campo STARDOM (FCN) permiten que las funciones maestras y esclavas Modbus se ejecuten simultáneamente. 

Para aprovechar al máximo las ventajas del GPRS, las RTUs inteligentes STARDOM FCN/FCJ de Yokogawa y el paquete de FAST/TOOLS SCADA tienen varias funciones que reducen el número de paquetes que se deben enviar. Esto reduce dramáticamente los honorarios de la comunicación.

PID is an acronym for proportional band, integral and derivative. This control action allows a measurement (process variable) to be controlled at a desired set point by continuously adjusting a control output. These control parameters act on the error or deviation between set point and process variable.

Yokogawa first introduced its renowned SUPER CONTROL™ in industrial controllers over a decade ago. This is a fuzzy logic alogrithm that eliminates overshoot from the desired set point and mimics the control expertise of the most experienced operator.

La Medición del Flujo de combustible diésel es una aplicación relativamente básica del medidor de flujo. Sin embargo, la medición del consumo neto del combustible en un generador diésel de 2.2 megavatios es particularmente complejo. El motor diésel requiere una línea de suministro de combustible (combustible del depósito al motor) y una línea de retorno de combustible (combustible del motor al tanque).

Recientemente, varios analistas del ARC Advisory Group y miembros de la gerencia tuvieron la oportunidad de sentarse con el nuevo Presidente de Yokogawa y COO, Sr. Takashi Nishijima, y varios otros altos ejecutivos de Yokogawa para discutir la presencia mundial de la compañía en la industria del gas y el petróleo.

This white paper provides an overview of how Yokogawa believes its customers can best prepare for and position themselves to benefit from IIoT-enabled technology and solutions and digitalization in general to emerge as the successful connected industrial enterprises of the future.

Yokogawa’s industrial automation (IA) product and service offerings, industry domain knowledge, and VigilantPlant approach – which emphasizes safe, secure, and uninterrupted operations -- provide a solid foundation for an Industrial Internet of Things that specifically addresses the requirements of process automation, particularly for the OT side of the equation.　To be able to provide an equally solid foundation for the IT side, Yokogawa is partnering with Cisco Systems and other industry leaders.

Vortex flow meters utilize a fluid phenomenon in which frequencies of Karman vortex streets released from a shedder bar inserted in a flow are proportional to flow velocities.

One solution packaged for production control systems today is a system comprising a PLC and SCADA (Supervisory Control and Data Acquisition) software that runs on a PC. An advantage of these systems is that they can be configured at considerably lower cost than systems that use dedicated devices as they use commercially available PCs.

Wireless technology has a long history, and it began around the time that James C. Maxwell theoretically predicted and then proved the existence of electromagnetic waves in the 1860s, and when Heinrich R. Hertz experimentally confirmed the actual existence of the electromagnetic wave in 1888.

Vortex flow meters have been appreciated by users as volume flow meters, which can, in principle, be applied to any flow measurement of liquid, gas, or steam. Volume flow measurement is enough for substances with small variations in density such as liquid. 

In 1988, Yokogawa launched the ADMAG series of magnetic flow meters with increased resistance to fluid noise and zero stability, employing dual frequency excitation which was developed based on its long-cultivated technology for flow measurement. Since then, the ADMAG family has augmented its application range with such models as explosion-proof and integral types, and a capacitance type.

Since the release of the DPharp EJ series in 1991 and the DPharp EJA series in 1994, nearly 1.2 million of these transmitters have been operating all over the world. Recently, we have also developed the EJX series of even more compact, lightweight and advanced transmitters with multi- sensing capabilities built using silicon resonant sensor technology.

Sample systems are a crucial component of and have a significant impact on the performance of a process gas chromatograph analyzer. When working on sample systems, you must have a constant awareness of time delays. This fundamentals webinar will take the mystery out of lag times.
