Model 3i – Basic Force / Torque Indicator

The Model 3i force indicator is a highly versatile and user-friendly digital tool designed to work seamlessly with a wide range of remote force and torque sensors. Whether you are upgrading your current testing environment or building a new quality control station, this digital force and torque indicator provides the reliability and precision required for demanding industrial applications.

One of the standout advantages of the 3i series is its exclusive Plug & Test™ technology. Unlike traditional setups where calibration is tied to the display unit, all configuration and calibration data is saved directly within the sensor’s smart connector. This allows for true interchangeable force sensors – meaning you can swap different load cells and torque sensors on the fly without needing to recalibrate the indicator. Furthermore, all sensors used with the 3i are fully forward-compatible with the advanced 5i series, making future equipment upgrades effortless.

Built for accuracy, the basic force torque indicator shares its intuitive menu structure and robust specifications with our industry-leading Series 3 digital force gauges. It boasts an impressive high-speed sampling rate of 2,000 Hz, ensuring that you capture accurate and repeatable results even under the most dynamic and rapid test conditions.

Data visibility and management are streamlined for the user. The device features a large, backlit graphic LCD that displays clear, easy-to-read characters. Navigating through the gauge’s features and configurable parameters is simple via the accessible menu. For visual monitoring, the display includes an analog load bar that provides a real-time graphical representation of the applied load, alongside programmable set point indicators designed specifically for pass-fail testing.

When it comes to data collection, the USB data output ensures quick connectivity to your PC. Every unit comes standard with MESUR™ Lite data acquisition software, which tabulates continuous or single-point data seamlessly. With a convenient one-click export to Excel, further data manipulation and reporting for your load cell measurement tasks become incredibly efficient.
