The pi Peak Load Indicator is a simple, low cost indicator that measures peak load. Load rate indication is available as an option for those applications that require accurate indication of load rate. The pi Peak Load Indicator is ideal for tension, compression and flexure testing on materials testing machines. It is rugged, easy-to-use and the pi's accuracy exceeds ASTM E4 requirements.

Typical applications include:

  • Measuring peak load in tension or compression
  • Measuring pull-out or press-in forces
  • Concrete cylinder testing
  • Cement cube testing
  • Beam flexure testing
  • Remote on-site testing
  • Proof load testing

pi Peak Load Indicator features:

  • Display live load and peak load numerically.
  • Optional load rate indication in force units per second.
  • Load and load rate can be viewed simultaneously.
  • Select engineering units of Lb, N, KN, and Kg.
  • Software programmable calibration with password protection (No potentiometers to adjust.).
  • Calibration is stored in permanent nonvolatile memory.
  • Accuracy exceeds ASTM E4.
  • Resolution greater than 1 part in 8,000,000 (23-bits).
  • End of test sample break detector set for 50% of peak load.
  • Start test threshold set in firmware.
  • Auto-Test-Reset automatically enables the indicator for the start of the next test without requiring operator interaction.
  • 0.38" high characters and a 60 degree sloped face for easy viewing.
  • Rugged keypad overlay with tactile keys and non-glare non-scratch screen.
  • Compatible with full bridge strain gage load cells and pressure transducers.
  • LVDT type transducers require optional LVDT conditioning module.
