Many processes change their characteristics with the application of heat. See terms — opens in a new window or tab. International postage paid to Pitney Bowes Inc. As a Reseller of high tech equipment, we professionally packaged for safe delivery.

Credit cards processed by These are some of the factors that may make one controller more suitable than another for a particular system to be eutotherm. The results of the evaluation are shown in FIG. See other items More An item that has been used previously.

Please send reseller form to: The longer the ITC, the more slowly the power level of the controlled heater is shifted. Derivative Action is the most beneficial control action in causing a controlled system to recover from small perturbations.

Reduce the PB until the control loop oscillates and measure the period of oscillation, T. The EAROM stores all the information necessary to define the controller and includes the data for transducers, linearization, output and alarm definitions and calibration constants. International shipping and import charges paid to Pitney Bowes Eurother. Seller assumes all responsibility for this listing.

That is the primary advantage of self-tuned controller. This item will be shipped through the Global Shipping Program and includes international tracking. Self-tuning controller — Eurotherm Corporation The program returns to the self-tuning algorithm in step No. Description Postage and payments. Add to watch list Remove from watch list.

The self-tuning controller as set forth in claim 33, wherein said means for controlling returning the self-tuning controller to a predetermined control routine; and re-entering the self-tuning programmed control at least subsequent to any one of the incrementation of said integral counter, storing X minthe storing of X maxsaid controlling means controlling said self-tuning controller in a normal three term control mode, and the enablement of said adaptive control mode.

With the use of a microprocessor such a control parameter is now adjustable. Customer support Technical helpdesk. This item will be sent through the Global Shipping Programme and includes international tracking. Skip to main content. It is in good physical condition but it has not been tested. For example, some controllers may provide excellent overshoot inhibition as an inherent characteristic, or perhaps superior response to setpoint changes.

A method for self-tuning as set forth in claimfurther comprising: Additionally, such control systems generally require that the operator respond to a number of questions prior to, or during, tuning.

A method of self-tuning a controller as set forth in claim 14, further comprising returning the program to a predetermined routine for controlling the controller and re-entering the self-tuning programmed control at least subsequent to at least one of the steps of incrementing said integral time counter, the recording of X minthe recording of X maxcontrolling the controller with normal three term control, and enabling said adaptive control mode.
