What does a sensor amplifier mean? Under what circumstances does it require equipment?

　　amplifierThe function of is to improve the quality and speed of signal transmission by converting and transmitting signals, making signal transmission more stable and efficient. For example, collecting millivolt level output signals from sensors and amplifying them to form volt level signals.

Amplifiers can be widely used in various industrial fields, mainly connected to various strain gauge sensors such as load sensors and pressure sensors in industrial measurement instruments. They have physical quantities such as weight, force, pressure, displacement, torque, etc., as well as analog signal output, digital output, small output, BCD output, RS-232 output, and other functions applied to control and management.
　

The measurement system using load sensors and the system using pressure sensors can be applied to various industrial fields such as iron making, cement, food, pharmaceuticals, chemistry, and can be used in conjunction with various machine tools and industrial robots. It is also widely used in experiments, suitable for measurement, monitoring, management, control, and other purposes. Due to its characteristics of facilitating automation, labor-saving, quality management, and safety management of production lines, it is widely used in multiple industrial fields.

Whether the sensor needs to be equipped with an amplifier depends on the on-site working conditions. The conventional output signal of the sensor is an analog millivolt signal, and the output signal after being equipped with an amplifier can be a 4-20mA or 0-10V standard signal. If the device connected to the sensor can receive analog millivolt signals, there is no need to equip an amplifier. If the device connected to the sensor can only receive standard signals, an amplifier needs to be equipped for use together.
