E-Scale IIoT-Ready Intelligent Scale

The E-SCALE-6500 is an IoT ready scale with integrated weight processing and communications via popular fieldbus communications such as EtherNet/IP, Profibus-DP, Modbus and Ethernet TCP/IP.  

IIoT Ready Intelligent Scale with Integrated Communications

The new Hardy E-Scale Bench scale series is the world's first IIoT-ready (Industrial Internet of Things) scale base. It includes an integrated Hardy weight processor for direct network connection for either EtherNet/IP® or Profibus-DP® networks. Depending on configuration, the E-Scale offers complete flexibility in size and capacity for use in a wide range of weighing applications. E-Scales eliminate possible failure points and save the cost of extra splice-boxes and other components.

With their rugged construction and stainless steel tops, E-Scales are a great fit for dry food processing, laboratory and industrial installations. The E-Scale line of bench scales comes in a variety of configurations with a built-in interface for direct connection to a PLC, PAC, DCS or PC. All E-Scales come standard in 12”x12” and 24”x24” sizes, and range in capacity from 33 lbs – 1300lbs (15 kg to 600 kg).

The covers are all stainless steel for durability. The bases have no bearings, spirit levels, or moving parts that can be damaged or wear out. They come standard with Hardy Process Toolbox features, including Waversaver®, C2®, Webserver, and Rockwell Automation integration tools such as Faceplates, and Add-on-profiles.

E-SCALE-6500**

IIoT ready scale with integrated weight processing and communications. No DIN or panel space is required. The E-Scale-6500 delivers stable processed weight with a resolution of 1:10:000, and an update speed of 110 updates per second (processor, display and comm.). Communications protocols supported include:

  • EtherNet/IP (-EIP models)
  • Ethernet UDP
  • Ethernet TCP/IP(Embedded Webserver)
  • Modbus RTU
  • Modbus TCP (-EIP models)
  • Profibus-DP (-PB models)

** User must supply 24VDC to the scale

E-SCALE-6610*

Capable of powering up to 20 scales daisy chained up to 50 ft from beginning to end to a single Hardy HI 6600 Gateway Module. The Gateway Module provides a Single Ethernet connection back to the PLC/PAC or PC – No additional power is required! Gateway Module has an optional panel mount multichannel display that can be used to operate connected E-Scales.

HI6600 Gateway communications include:

  • EtherNet/IP (-EIP models)
  • Profibus-DP (-DP models)
  • Ethernet TCP/IP(Embedded Webserver)
  • Modbus RTU

Even in noisy environments with excessive amounts of mechanical vibration, the E-Scale-6610 provides a steady 1:10:000 resolution with 110 updates per second over its variety of communications protocols.

Hardy Process ToolboxHardy Process Toolbox

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves you 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 E-Scale 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.

E-Scale-6500-XP ONLY 
Hardy's patent-pending WAVERSAVER+ patent pending adaptive algorithm that selects from a bank of 7 noise filters, and uses the optimum mix to provide a stable weight under static conditions. 

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.

INTEGRATED TECHNICIAN® Operator Diagnostics
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 individual system weights and voltages, as well as  pass/fail, stability and zero verification 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 pasword protected parameters from anywhere on the Ethernet network.
