The aforementioned criteria have special application of the following types of loads: A method for self-tuning a controller as set forth in claim 1 further comprising monitoring the control response to perturbations and altering the PB setting if said at least one load characteristic does not reach setpoint within a eeurotherm time frame with respect to the time counted by said integral time counter with the controller demanding a particular type of control power at the time of a perturbation.
All equipment is sold AS-ISno warranty unless otherwise specified in description.
See all ekrotherm definitions – opens in a new window or tab. The Cohen and Coon PRCT evaluates the process near ambient and therefore could provide a misrepresentation of the process response at setpoint. Attain the required operating tmperatures as quickly as possible without any overshoot.
Delivery times may vary, especially during peak periods.
However, such techniques could be employed in designing a self-tuning controller in accordance with the concepts and principles of the present invention in those applications where such slow response was acceptable.

Back to home page. Thermocouple cold junction compensation is provided by a custom thick film circuit not shown. An external potentiometer can be connected to the Remote Analog Setpoint circuit to provide an external potentiometer setting of the maximum heat power level. International buyers and unusual domestic shipping please E-mail in advance for shipping eurothdrm handling charges.
Eurotherm Temperature Control, Process Control, Measurement and Data Recording
The power to the load is then turned on full. The self-tuning algorithm of the present invention will reasonably tune any load that has the following characeteristics:. However, the amount of power applied to the 801 upon start-up is not critical to the invention and any amount of power can be applied depending on the application to which the self-tuning control of the invention is applied. Another aspect of self-tuned controllers is that the control algorithm is eurothrrm tailored for a certain industry’s application and requirements, and therefore is limited in its range of control applications as it can only optimally control a specific type load.

Continuous operation of the scroll button selects the parameters in turn. Decades of experience in providing world-class process controlrecording and automation are supported by a continuous research and development programme to ensure our solutions meet the modern challenges faced across a wide range of industries. However, it is to be understood that the self-tuning controller of this invention can be adapted to any control theory approach using the techniques disclosed and described herein.

Many processes change their characteristics with the application of heat. The controller can enter a self-tuning mode by manual depression of the scroll button as follows. The description of the operation of the self-tuning algorithm continues with the program steps illustrated in FIG. The time for the load temperature to rise to eurothedm peak value and the amount of temperature rise are determined as such data is related to the P, I and D parameters of the self-tuning temperature control of the load.
Resume making your offer if the page doesn’t update immediately. Power to the load is turned on if the comparison in step No. The scroll button is depressed until the operator detects that “tn” appears on the front panel display.
Mount Pleasant, Michigan, United States. The drive signals for the FIP are output from the microprocessor through the display driver circuit. Non-volatile storage is a critical feature if the controlled system is in an environment where brown-outs or black-outs are common. Covers your purchase price and original shipping.
Eurotehrm that determination is positive the algorithm proceeds to step No. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. The method as set forth in claim 39, further comprising monitoring the control response to a perturbation; altering a power 180 setting of the load if said at least one load characteristic does not attain setpoint in a given time frame with respect to ITC with a given type power to the load.
This item will ship to United Statesbut the seller has not specified shipping options.
Once the load temperature has stopped rising and begins to fall at time t 3the PID tuning parameters may be calculated and inserted into the control algorithm. With an overdamped response, the PB is decreased by one table value or setting in the 8810 that heater power is being called for by the controller. The controller is adapted to be fitted with two alarms independently adjustable, either full scale, deviation or band types.
