Equipped with the “Hardy Process Toolbox” – a unique set of productivity tools that support industrial weighing functions – Hardy instruments provide valuable assistance in commissioning, maintenance and fault location. Each tool saves time, increases accuracy, improves efficiency or reduces risk in process weighing applications, while saving OEMs considerable development and system integration time.

Our customers such as Mars, Royal Canin and Goodyear are convinced by the particular benefits:

• Practical: the fast and simple C2 Electronic Calibration without the need for test weights
• Stable: the automatic vibration suppression (WaverSaver)
• Secured: settings and adjustment data are securely stored for back-up and transfer (Secure Memory Module)
• Networked: the integrated web server enables remote access and setup of the instruments via Ethernet (Embedded Web Server)
• Built-in support: Hardy instruments are equipped with a powerful diagnostic and troubleshooting feature (Integrated Technician)
• Active support: for planning, installation and operation of the Hardy devices, our competent B+L support is always at your side.

Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy-to-maintain and save you time, money, raw materials and/or finished product.

For process weighing applications, we offer a selection of suitable Hardy solutions here:

HI 1756-WS and -2WS  –  Single and Dual ControlLogix® Weigh Scale Modules

HI 1769-WS and -2WS CompactLogix® Modules  –  Small size, high performance!

Hardy’s HI 1756-WS is available as a single slot, single or dual (-2WS) weigh scale module that mounts in Rockwell®ControlLogix® Chassis.
Hardy’s compact weigh scale module HI 1769-WS is available in single or dual channel models for use in Rockwell® CompactLogix® PLC controllers (and certain MicroLogix™1500).

These PLC weighing modules read and condition weight and diagnostic data from one set or two separate sets of strain gauge load sensors or load cells and communicate this data over the I/O chassis backplane to the PLC processor. Both modules reduce installation costs, as they do not require an external Ethernet switch or router.

Hardy Process Solutions is an Encompass Global Partner with Rockwell Automation, which ensures a smooth workflow with their equipment.

SOLID PERFORMANCE
The HI 6600 enhances productivity of manufacturing systems by digitally suppressing noise and dramatically reducing scale settling time. Even in noisy environments with excessive amounts of mechanical vibration, the HI 6600 provides a steady 1:10,000 resolution in oz, lb, ton, g, and kg with 110 updates per second over its variety of communications protocols.

EASY INSTALLATION
Just snap the number of weight channels you need onto a DIN rail, connect power, cable the units together to the Gateway Module using standard Cat5e cable, connect sensors, power up and press DISCOVER. The system will automatically identify all the modules connected together and make them addressable for set-up and calibration through the PLC, embedded Webserver or optional display. A Rockwell EDS_AOP simplifies integration using RSLogix.

The HI 6500 series are EtherNet/IP® enabled weight processors with a Rockwell Add-On-Profile (AOP) and Faceplate/AOIs. They have a big, bright multi-channel display and deliver fast, high-resolution weight readings. They also feature Profibus-DP, Modbus, Analog, and Ethernet communication options.
Weight processors are used as front ends to control systems or standalone for all types of general weighing applications. Operating blind or with a display, they measure, condition and communicate weight without any need to control.

SOLID PERFORMANCE
The HI 6500 series delivers stable processed weight with a resolution of 1:10,000 and an update speed of 110 updates per second (processor, display and communications). They enhance the productivity of process manufacturing systems where fast, precise weight-based controls are critical.

EXTREME WEIGHT PROCESSOR
The HI 6500-XP Extreme Weight Processor can process and output 660 updates per second of processed (stable) weight with a resolution of 1:30,000. The HI 6500-XP represents the state-of-the-art in processing uniformity and speed. A/D conversion, weight processing and the communications port ALL update at 660 times per second, providing the PLC with the latest processed weight reading every 1.5 milliseconds. Many competitor’s products execute the A/D conversion at one frequency, then process the weight and communications ports at a much slower rate typically 20 to 50Hz, only providing the PLC with an update every 20 to 50 milliseconds. The HI 6500-XP results in better product consistency and product yields while reducing processing time, waste time and materials. It is designed for applications where speed and accuracy are paramount to control and quality, and it’s ideal for high-speed filling, dispensing and check weighing, where materials are often fed and weighed in motion at high speeds.

INSTALLATION YOUR WAY
For panel mounting, simply drill five holes to mount the keypad/ display on the front and the instrument to the other side. For blind or remote mounting, just snap its built-in clip onto a DIN rail or mount on a wall. The HI 6500 series fits in a 2″ deep cabinet!

• Automatic closed loop control: continuously adjusts the feeder to deliver the desired feed rate
• True five-point automatic rate calibration: produces high feed accuracy for a wide range of feed rates
• Multiple configuration storage: stores hundreds of different system configurations
• Automatic feeder refill: starts and stops refilling without interrupting the feeding of material
• Convenient manual mode: allows manual speed control, with switch to automatic control at the touch of a button
• Various alarms, including rate tolerance and disturbance
• Graphics Display Mode: graphs actual feed rate vs. setpoint or operation percentage output
