Category: DATA LOGGER

Model: Bridge Strain

Avaibility: AVAILABLE

Call For Price

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 1,000,000 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 pushbutton start/stop feature allows the user to initiate or cease logging data in the field if desired.The MadgeTech Data Logger Software offers user programmable Engineering Units which allows collected data to be presented in the established unit being measured. Equipped with endless data analysis and reporting tools, the MadgeTech software simplifies device management and provides the user with graph, tabular or summary reports with the ability to export data to Excel as needed.

Stop Modes

  • Manual through software
  • Timed (specific date and time)

Multiple Start/Stop Mode

Start and stop the device multiple times without having

to download data or communicate with a PC.

Multiple Start/Stop Mode Activation

  • To start the device:

Press and hold the push button for 5 seconds, the green LED will flash during this time. The device has started logging.

  • To stop the device:

Press and hold the push button for 5 seconds, the red LED will flash during this time. The device has stopped logging.

Real Time Recording

The device may be used with PC to monitor and record

data in real time

LED Functionality

  • Green LED blinks:

10 second rate to indicate logging

15 second rate to indicate delay start

  • Red LED blinks:

10 second rate to indicate low battery and/or full memory

1 second rate to indicate an alarm condition

Password Protection:

An optional password may be programmed into the device to restrict access to configuration options. Data may be read out without the password.

Engineering Units

Native measurement units can be scaled to display measurement units of another type. This is useful when monitoring voltage outputs from different types of sensors such as strain gauges and load cells.
