  • Controller Specification
    With an increasing range of temperature and process controllers on the market it can be hard to select the most appropriate controller for your application. This whitepaper will walk you through the different criteria to consider when choosing your controller, helping you identify where cost
  • Implementing a PID Controller Using a PIC18 MCU
    Continuous processes have been controlled by feedback loops since the late 1700's. In 1788, James Watt used a flyball governor on his steam engine to regulate its speed. The Taylor Instrument Company implemented the first fully functional Proportional, Integral and Derivative (PID) controller
  • Process Control Application Note
    Most industrial processes require that certain variables such as temperature, flow, level or pressure, remain at or near some reference value (setpoint). Closed-loop control is used to achieve this. The process controller looks at a signal representing the process value, compares it to the desired
  • MICRO: APC/AEC
    Semiconductor's facility in South Portland, ME. While initial indications pointed to a less-than-optimum recipe, closer analysis revealed that the tools suffered from a chronic temperature problem. To correct the faulty process variable, the fab installed the Dynamic Neural Controller from Ibex Process
  • HVAC Flowmeter Applications
    has a high degree of accuracy and repeatability. The batch controller uses a prediction algorithm that increases the accuracy of the batch process. These features guarantee a precise charge and help to eliminate any refrigerant waste.
  • Medical Device Link . Innovative Injection Molding Techniques for the Medical Industry Four molding techniques open up a variety of new approaches to the design of medical components.
    . In the conventional molding process, coolant such as water or oil is circulated through the mold continuously while mold temperature is regulated by a controller such as a thermolator or chiller. This type of temperature control maintains a reasonably consistent water-inlet temperature to the mold
  • Optimisation
    Optimisation of the causticising process Janne Tolonen (i), Ossi Tolonen (ii) and Jukka Puhakka (iii) Neles Automation, Field Controls Div, PO Box 177, FIN-87101 Kajaani, Finland Traditionally the causticising process has been controlled by using a lime/green liquor ratio-controller, dT-controller
  • Fieldbus Part 2
    controller cabinets in safe-area spaces, and only allow I/O subsystems in process spaces. IS remote I/O was installed in the process space to interface to low-power solenoid operators for valve actuators, valve-position limit switches, rupture-disk indicators and transfer-panel proximity switches. The remote
