Tension and compression load cell with digital indicator for accurate force measurement in testing machines and structural tests.
Overview
The force-measurement system consists of an S-beam strain-gauge load cell and a digital force indicator. The S-shaped elastic element (alloy or stainless steel in shear/bending) carries bonded resistance gauges in a Wheatstone bridge, outputting a mV/V signal proportional to force (about 2.0 mV/V). The indicator supplies bridge excitation, amplifies and A/D-converts the signal, applies digital filtering, and displays tension/compression digitally with peak-hold, zeroing, engineering-unit switching, high/low alarms and RS232/RS485/USB. Accuracy reaches 0.03 class, capacities from kg to tens of tonnes; widely used in material testers, hopper scales, insertion-force tests, press-fit machines, crane scales and automation.

FAQ
Q1: What standards does the Tension-Compression Load Cell with Digital Indicator comply with?
A1: The Tension-Compression Load Cell with Digital Indicator is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Tension-Compression Load Cell with Digital Indicator be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
