Essential Interface Indicators for Load Cells and Torque Transducers

Interface continues to expand our line of instrumentation solutions. One of the top instrumentation choices is sensor indicators, valuable instruments for measuring force, torque, and weight with high precision. They convert the minute voltage difference a load cell generates into a clear, readable format.

Interface’s indicators come in various configurations to suit various testing needs. They include load cell indicators, torque transducer indicators, and multi-axis sensor indicators. These indicators cater to different testing environments, connectivity needs, and sensors. When pairing your instrument with a specific sensor, we recommend requesting a system-level calibration to ensure optimal performance.

We offer indicator form factors, including handheld, panel-mounted, bench-top, or rack-mounted for portability or permanent setups. Data transfer options include traditional wired or modern wireless connectivity for increased flexibility. To protect the instrument, enclosures are available that withstand harsh environments for reliable operation anywhere. Form options include:

  • Portable Indicators: Ideal for field testing or tight spaces, offering portability and real-time data capture.
  • Digital Indicators: Provide clear and accurate digital displays for easy reading.
  • Wireless Indicators: Transmit data wirelessly for untethered operation and improved efficiency.
  • Multichannel Indicators: Connect to multiple load cells simultaneously, displaying individual or combined readings.
  • Programmable Indicators: Offer advanced features for customized testing procedures.
