The Bridge101A is a compact, data logger that measures and records voltage, typically used in conjunction with strain gauges, load cells, and other low-level DC voltage sources. This device is designed to accurately calculate the output of the gauge to determine parameter levels such as stress, torque, strain, and pressure over a period of time.

Available in three different measurement ranges (±30 mV, ±160 mV or ±1200mV), the Bridge101A offers a reading rate of up to 4 Hz with memory capacity of 2,064,384 readings. The device can be configured to start at a specified date and time up to 24 months in advance or by using the push button start/stop feature.

The Bridge101A 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.

Note: MadgeTech recommends using 350 or 1000 Ω strain gauges. 120 Ω strain gauges can be used with the Bridge101A but it is not recommended as it will reduce the battery life, potentially increase noise level and limit the low end temperature operation.
