HARDY Process Weighing Electronics

B+L Industrial Measurements has since 2005 been the authorized sales and service partner of the US-based manufacturer Hardy Process Solutions for the European market. HARDY's wide range of weighing electronics is optimally tailored to Rockwell systems.

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:

• fast and simple C2 Electronic Calibration without the need for test weights
• automatic vibration suppression (WaverSaver)
• settings and adjustment data are securely stored for back-up and transfer (Secure Memory Module)
• web server allows remote access and setup via Ethernet (Embedded Web Server)
• diagnostic and troubleshooting feature (Integrated Technician)
• competent B+L support

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

Plug-in Weigh Scale Modules for ROCKWELL SPS

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

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

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.

Plug-in Module HI 1734-WS POINT I/O

The HI 1734-WS Point I/O Series Weight Processing Module is an ultra-compact plug-in module for Rockwell Point I/O chassis. It is a true weight processing module, just a ½“ wide and will have a Rockwell Add-On-Profile (AOP) that will automatically recognize the module when it is plugged into the Point I/O chassis.

The Hardy HI 1734-WS module is ideal for POINT I/O applications where fast, stable weight data and low-cost of ownership are important. The HI 1734-WS enhances productivity of manufacturing systems by digitally suppressing noise and reducing scale settling time.

HI 6500 / HI 6500-XP Weight Processors

The HI 6500 series weight processors deliver fast, high-resolution weight readings. They offer all common connection options and a big, bright multi-channel display for up to 4 instruments.

Weight processors are used as front ends to control systems or standalone for all types of general weighing applications, where they measure, condition and communicate weight.

Extreme Weight Processor Version with 6X the Speed and 3X the Resolution:

The HI 6500-XP Extreme 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 and it’s ideal for high-speed filling, dispensing and check weighing.

HI 6600 Modular Sensor System

Up to 30 Channels of Weight on one SINGLE Ethernet Connection!

The up to 30 weight processors of the HI 6600 system deliver their fast, stable, high-resolution weight readings to the Gateway Module, which sends the data to a PLC, PAC or DSC over a single fieldbus network connection. The HI 6600 provides a steady 1:10,000 resolution with 110 updates per second.

Ideal for applications that require more than one channel of weight, such as inventory tank farms, batching systems and multi-head filling machinery; each channel of the HI 6600 processes signals from up to four connected load cells, then outputs the entire system’s weight data.

HI 4060 Loss-in-Weight Rate Controller

Hardy’s HI 4060 is a compact, single-feeder, closed-loop rate controller for use in a variety of gravimetric applications, including auger, belt and vibratory-based feeders, or to retrofit volumetric feeders converting them from volumetric to gravimetric.
Auto closed-loop control of feeder speed, auto. five-point weight and rate calibration
