Description

The Bridge Amplifier+ unit allows for a new range of sensors to be connected to the Shimmer3 platform. The unit allows for strain and load cell data acquisition for force and resistance measurement. The module contains a bridge amplifier, excitation source and connector enabling force measurement with the Shimmer, as well as a buffered resistance divider amplifier to enable resistance measurements. The Bridge Amplifier+ module is ideal for all load, weight, force, torque and pressure measurements and the resistance divider input is suitable for variable resistance sensors, such as a temperature probe. Features & Benefits Specific Features ◉ Interface strain gauge or load cell sensors with Shimmer3 to measure load, weight, force, torque or pressure ◉ Interface variable resistance sensor with Shimmer for example, temperature sensitive resistor to measure ambient, skin-surface or other temperatures ◉ Provides excitation source for strain gauge or load cell, meaning no external voltage source is required ◉ Excitation source and amplifier enable are software controlled, allowing optimisation of power consumption ◉ Two channels of output from bridge amplifier, providing both low and high gain; low gain is ideal for bipolar inputs, whilst high gain provides additional 3x gain for unipolar load cells ◉ EEPROM storage device enables expansion board detection and identification, as well as 2032 bytes of data storage available to user. Benefits over previous generation Strain Gauge ◉ Bridge Amplifier input for Strain Gauge as well as resistance divider input ◉ Strain Gauge/Resistance data can be measured simultaneously with 10DOF kinematic data
