A bridge circuit is a common arrangement in a variety of different measurement applications, but particularly in force and pressure transducers. The output of these sensor types is proportional to the excitation voltage applied, and is measured in millivolts. Signal conditioning and interfacing these sensors with a microcontroller or a data acquisition system requires a precision voltage source and a precision high gain amplifier stage. This board provides both in a convenient package. Gain is programmed with a single resistor. Excitation is jumper selectable from 1.27V to 10V. 

In addition to force and pressure transducers, this bridge circuit can be used with strain gauges, thermistors, RTDs, or any other bridge or resistive type sensor. It can also be used as a precision differential amplifier simply by neglecting to connect the excitation. The versatility of this module is further increased by onboard charge pump that allows it to develop ±10V bipolar output from a 6V to 30V single-ended voltage supply.

Key Features
  • Precision excitation jumper selectable between 1.24V, 2.5V, 5V or 10V
  • Resistor programmable gain from 4 to 10,000
  • ±10V bipolar output
  • 6-30VDC single ended power supply
  • Resistor adjustment of offset
  • Sample Applications
  • Excitation and signal conditioning for load cells and millivolt output (4 wire) pressure transducers.
  • Strain gauges, either in bridge configuration or with external resistors.
  • RTDs and thermistors, with external bridge resistors
  • Any differential amplifier or instrumentation amplifier application
  • Connector kit

Does the "Ink"Color Bag have silver tone hardware? (Chain)? It is hard to tell in photo

I bought the black one and the chain is gold color. Not sure of the ink bag.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
