The HADI direct reading measurement system is capable of meeting the portability, sensitivity, and stability demands for both lab and field use for strain gage based load cell instrumentation. Morehouse is pleased to present a cost effective “true” 6-wire sensing solution.    


Morehouse HADI

 

The Morehouse "High Accuracy Digital Indicator" (HADI) is one of our latest efforts to provide best of breed products & services to force/torque measurement processes. This six-wire sensing Analog-to-Digital USB converter offers the use of our Morehouse direct reading software, with multiple load cell configurations, longer cables, and lower uncertainty. Non-Linearity less than 0.002 % of full scale, +/- 20-bit system, with 172 A/D conversions per second. Direct Reading according to ASTM E74, E2428, and ISO 376. Coefficients from fitted curves are used to convert mV/V to Engineering Units; lbf, kgf, & Newtons

 

·       A true 6 wire sensing USB device

·       ASTM Class A lower limits better than 2 % when paired with Morehouse Ultra-Precision Load Cells

·       System is fully USB powered, eliminating excess power cables

·       Direct reading according to ASTM E74, ASTM E2428, and ISO 376 

·       For calibration of load cells, testing machines, and other force or torque systems

 

Note: Morehouse HADI systems require a computer to get powered and display load or torque values.  The HADI system with software complies with ASTM E74, E2428, and ISO 376.  Accreditation bodies require compliance with the standards. The HADI system with Morehouse software eliminates the need to use load tables, excel reports, and other interpolation methods to ensure compliance with these standards.  NCSLI RP-12 states in section 12.3 “The uncertainty in the value or bias, always increases with time since calibration”.     When the drift occurs, the indicator needs to be reprogrammed, and most quality systems require an "As Received" calibration, then the indicator needs to be reprogrammed, and an "As Returned" calibration is performed.   The actual level of work results in calibration costs that are much higher than they need to be. Morehouse developed our HADI systems with software to avoid the excess costs as the coefficients used in the software are based on mV/V values and the "As Received" and "As Returned" calibrations are the same with the end user only needing to update the coefficients in the software.   The software allows for conversion from mV/V to lbf, kgf, kN, N and reduces the overall cost for the customer while meeting the quality requirements in ISO/IEC 17025:2017.
