HI 4050CW Check Weighing Bundle

The HI 4050CW Check Weighing bundle is perfect for building new systems for both static and dynamic check weighing or retrofitting the weight measurement electronics of older, less reliable systems. The system is designed for industrial applications requiring a fast, accurate and repeatable response to change in weight conditions.

Give Your Check Weighing an EDGE

How important is using a Hardy Check Weighing bundle in your process?
We’ve done the math for you:
  • Your system produces 250 cans packs per minute with an uptime of 85%/year.
  • Overfill is 2 grams per pack.
  • Product cost of $0.001 per gram.
  • Overfill cost per year = $223,380
  • Reduction of just 1 gram overfill per pack =$111,690 savings per year.

The high speed HI 4050CW check weighing system can process up to 250 high resolution (1:30:000) weight measurements per second. The 4050CW consists of a special version of the HI 4050 weight controller connected to up to four analog load cells and a Hardy junction box.  Hardy Checkweighing Bundle

The HI 4050CW is perfect for building new systems for either static or dynamic check weighing or retrofitting the weight electronics of older, less reliable systems.

The 4050CW breaks the traditional analog strain gauge “speed barrier”, without the cost of MFR (Magnetic Force Restoration or other similar high speed/resolution technologies) yet it still delivers accuracies of up to 0.01% of full sensor capacity.

A HI 4050CW system is made of Commercially Available Off the Shelf (COTS) parts that are easy to understand, maintain and troubleshoot. Connect to your plant-wide system using standard protocols such as EtherNet/IP, Devicenet, ControlNet, Allen-Bradley® Remote I/O, Profibus-DP, Modbus TCP/IP, or Analog. It features a lower Total Cost of Ownership because it's simple to use, calibrate, integrate, and maintain. A Rockwell Add-On-Profile makes it easy to configure with RSLogix.

Smart features of the HI 4050CW include EDGE detection, an algorithm that optimizes when weight readings are captured:
  • Automatic EDGE detection starts weight processing the instant a load settles onto the scale by monitoring changes in the signal waveform from connected load point.
  • Also works in conjunction with up to two additional external sensors such as photo-eyes to optimize process timing of weight readings.

Connect the HI 4050CW to up to four ADVANTAGE® load points and a Hardy IT junction box for high speed, high resolution weight readings compatible with C2 calibration

Hardy Process ToolboxHardy Process Toolbox

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration and Integrated Technician® to name just a few.

The HI 4050CW features the following Toolbox technologies:

WAVERSAVER® vibration eliminator
Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.

WAVERSAVER+ adds two patent pending adaptive filtering algorithms that decrease the time that the HI 4050CW displays accurate, stable rate readings by a factor of three.

C2® (or eCAL) Electronic Calibration
The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.

Embedded Web Server
Access your instrument from any computer browser, easing setup and making diagnostics fast and easy.  Use the Embedded Web Server to set up all parameters from anywhere on the Ethernet network.

Secure Memory Module Stores Configuration Data
Hardy's Secure Memory Module (SMM) uses a standard SD card to automatically back up critical weighing system data, and allowing you to transfer it to another like controller in a few minutes.  You can also use the card to easily back up your controller data onto a PC.

CHECK-MASTER is a set of software tools that support check weighing functions and are part of every Hardy Check Weighing solution. There are tools for both static and dynamic check weighing.
