AND Weighing AD-4410 Weighing Indicator with DSP Technology

The High-Performance Digital Filter provides high accuracy/high speed weighing in environments with vibration problems. The AD-4410 greatly reduces the costs and maintenance required for anti-vibration equipment since it copes with vibrations without requiring many mechanical measures. What's more, conducting weighing while applying vibrations, once an extremely difficult task, is now possible. The High-Performance Digital Filter only requires one setting. For this reason, optimal settings for vibration cancelling can be found after just a few tries.

Powerful Vibration Cancelling Feature The High-Performance Digital Filter provides high accuracy/high speed weighing in environments with vibration problems. The AD-4410 greatly reduces the costs and maintenance required for anti-vibration equipment since it copes with vibrations without requiring many mechanical measures. What's more, conducting weighing while applying vibrations, once an extremely difficult task, is now possible. The High-Performance Digital Filter only requires one setting. For this reason, optimal settings for vibration cancelling can be found after just a few tries.

Can be Calibrated in an Environment with Vibrations Until now, to conduct calibration, sources of vibration had to be completely stopped, or calibration had to be conducted on weekends or holidays when machines are not active. However, even in an environment with vibrations, the AD-4410 can be calibrated at any point, so costs incurred from stopping production or calibrating on weekends or holidays will disappear

Average Holding Function This function allows averaging a specified interval of data and holding it. This mode is convenient for situations where reliable data cannot be taken even when the High Performance Digital Filter is used, like when measuring the weight of a restless animal or something that is fluctuating in weight. In addition to the average holding function, normal hold and peak hold functions can also be selected. The hold start point can be selected based on one's needs, for example, using an external signal, using the F key on the front, or timing it to when the zero band has been exceeded.

Non-Linear Correction Using High-Order Equations Due to the nature of weighing instruments, sometimes linear deviation can occur even if zero and span calibration are carried out. This correction function minimizes those linearity deviations.
Up until now, linear correction has been commonly used, but AD-4410 corrects linearity deviations that linear correction can't compensate for by using high-order curves, enabling more accurate weighing.

User Input, User Output
The AD-4410 has 3 input points and 3 output points for its control I/O. Users can select what functions to assign to the control I/O. We've put in two new functions: user input and user input/output. User input/output can be used for whatever purpose the user wishes. One could turn on certain output terminals using RS-232C or RS-485 commands, or confirm certain Input/output terminals' situations using the front panel's display. For example, it would be useful in a situation where you want to monitor photosensor input using PC or PLC, but there's no readable input port available.

Extensive Connectivity Control I/O, RS-232C, and current loop all come standard, RS-485 and the second RS-232C channel are options. There are 3 input and 3 output points, and you can freely select from 13 types of input functions and 18 types of output functions.

Comparator Function One can establish an upper and lower limit, and use the control I/O output to output HI, OK, or LO.

RS-232C Comes Standard with Optional RS-232C/RS-485 Functionality Data can be transmitted at high speed and commands essential to weighing can be sent. Control commands such as hold point commencement and release, setting commands such as upper and lower limits, and weighing data uptake functionality are built-in.

Additional Functions

Zero Band Detection FunctionThis function allows setting a zero band, so that gross weight or net weight will be adjusted to zero within that range.
Zero Tracking FunctionAutomatically tracks gross weight zero fluctuations, constantly maintaining gross weight at zero.
Power On-Zero FunctionAutomatically sets gross weight to zero when power is switched on.
Gravity Acceleration CorrectionWhen the area the balance was calibrated using weights at and the area where measurement takes place are far apart, entering the gravity acceleration can correct for inconsistencies.
Dual RangeBy setting two weighing ranges and changing the scale interval displayed, you can create a multi-interval instrument.
