The Bridge120 is a differential input, bridge/strain data logger. Includes standard calibration certificate. Read More >

Key Features:

  • Compact Size
  • Available in 4 Measurement Ranges
  • Accepts Signals from Common Voltage Sources



The Bridge120 is a compact, bridge/strain data logger featuring a differential input and a 20 Hz processing speed. The Bridge120 accepts voltage signals from strain gauges, load cells, and other low-level DC voltage sources. This device is perfect for monitoring stress, torque, strain, pressure conditions and data from many other sensors/transducers.

The Bridge120 can measure and record data for up to 32,767 readings. Its non-volatile memory provides maximum data security even if the battery becomes discharged.

The Bridge120 is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
