Application Note
Tank Level Control and Monitoring in Food Manufacturing Processes
Thumbnail
Overview:

With advances in process automation comes a greater need for level measurement and control. As pressure on at the bottom surface of a liquid is proportional to the height of the liquid's surface, you can measure pressure using a differential pressure transmitter to detect the level of the liquid, acquire the data on the UT75A Digital Indicating Controller, and use the measurements to control the tank level.

Overview:

Adding the CP calculation option to the advanced UT75A Digital Indicating Controller enables CP (Carbon Potential) control. CP calculation can be carried out with just one line of a UT75A ladder program.

업종:
Can a moving average calculation be performed on input?
(ns-faq-ut-2139-program)
Yes, with a ladder program. The model that supports this is the UT75A. You can use up to 3 moving average (MAV) calculations.
Is there a tool for changing parameters and custom calculations when upgrading from the UT750 to the UT75A?
(ns-faq-ut-2174-spec)
No, there is no conversion tool, but note that custom calculations can be replaced with ladder sequence programs. See (TI 05P01B41-03EN): “Conversion Table of UT750 Custom Computation into UT75A Ladder Program.” ...
When switching input with 2-input switching control, doesn't the control output suddenly change (bump)?
(ns-faq-ut-2057-spec)
When the input switches, the controller tracks the PV and suppresses sudden control output changes (bumpless).
I want to use 2 communication systems.
(ns-faq-ut-2085-select)
You can install 1 system from Ethernet/CC-Link/DeviceNet/PROFIBUS-DP/RS-485 on the UT75A, UT55A, UP55A, plus an additional system of RS-485. Specify these when ordering.
With the UT55A, UT75A, and UP55A, is there a difference between selecting RS485 communication with the 2nd digit of thesuffix code versus the 3rd digit?
(ns-faq-ut-2086-select)
Yes. The communication protocol is the same, but note the difference below. You can also install two systems for use with separate protocols. The maximum speed of RS485 communication using the 2nd digit of the specification code is 19.2 kbps. The UT5...
I want to perform cascade control with one UT, but I can't switch from auto to cascade.
(ns-faq-ut-2095-setting)
Check whether the input on the primary loop is normal.If the input is abnormal, the unit won't switch to cascade mode.
I'm doing cascade control. How do I do auto-tuning?
(ns-faq-ut-2103-setting)
First, set the secondary controller to AUTO operation (CAS goes out), then auto-tune that controller. Next, place it in the cascade state (CAS lights), then auto-tune the primary controller.
