1-channel amplifier board for strain-gauge transducers:

• stable 5 V or 10 V current delivery to transducer gauge bridge
• signal input in differential mode with common mode rejection
• high input impedance (~3.109 ƒÇ) prevents transducer loading
• low-pass filter at 500Hz, 35 Hz, 10 Hz, 0.1 Hz.
• high-pass filter at 0.075Hz, 0.25Hz, 1Hz or none
• two levels of balance tuning: coarse tuning, fine tuning through multirevolution potentiometer
• external gain setting from x 1 to x 5 (or x 50 to x 250)
• front face gain multiplication through preset switch (x 1, x 2, x 5, x 10, x 20, x 50, x 100, x 200, x500, x 1000)
• output to analog/digital converter (0 to 10 V or +/- 5V) for connection to computer system (emka TECHNOLOGIES product or other)
• AC/DC switch to allow suppression of constant signal component
