Product Notes
The Bridge101A Data Logger measures and records
voltage, typically used in conjunction with strain gauges,
load cells or other low-level DC voltage sources. This
device is designed to accurately measure and record the
output of the gauge to determine parameter levels such as
stress, torque, strain, and pressure on a structure or item
over a period of time.
Available in three different measurement ranges (±30 mV,
±160 mV or ±1200 mV), the Bridge101A offers a reading rate
of up to 4 Hz with memory capacity of 2,000,000 readings
(memory wrap optional). The device can be configured
to start at a specified date and time up to 24 months in
advance and the push-button start/stop feature allows the
user to initiate or cease logging data in the field if desired.
*MadgeTech recommends using 350 or 1000 Ω strain gages. 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.
