Lots of info related to circuit, load, interface devices, current, sensitivity, material, force, configuration, example, source impedance, interface, and adjustment are described in this guide. Inside this guide you can get information related to source, response, specific application, current limiting resistor, sensor, divider circuit, relay, models, devices, applications, basic sensor, and output.
This guide presents discussion like gain, limiting resistor, current limiting, divider, application requirement, durability, application, impedance, sensor configuration, interface circuits, bias currents, and reference voltage. Below are chosen from the guide:
This basic interface provides a simple force input > voltage output conversion. The value of Ro drives the voltage output response. The output voltage is proportionate to the value of Ro, i.e., as the value of Ro increases, the voltage output increases. In the schematic shown the output voltage (Vo) increases as the force applied to the sensor is increased. A value between 2.7kΩ~100kΩ is recommended for Ro depending upon the desired force sensitivity and current limiting considerations. + Vout Ro Recommended op-amps for the interface are LM324 or LM358. Their low bias currents tend to reduce the possible error due to the source impedance of the voltage divider.
Giving more content, this guide explains more around resistance, output voltage, circuits, voltage, particles, switch, currents, low bias currents, double sided adhesive, value, voltage divider, and temperature.
