What are sensor amplifiers?

Sensor amplifiers make a sensor's raw output more useful. They use application-specific circuitry to condition a sensor's signal into a form that's better suited to the next stage of data processing.

In most cases, this means increasing the magnitude of small signals so that data-acquisition devices can measure them more accurately. Yet some amplifiers for sensors can also perform other functions, such as converting the sensor signal into a new output.

What are the different types of sensor amplifier?

We offer a diverse range of amplifiers for sensors, categorized according to their function and the sensors with which they're used in conjunction. Our catalog includes but is not limited to:

• Current sensing amplifiers – These amplifiers monitor current flow across a sense element by converting it into an amplified voltage, helping to optimize system performance and protect against overcurrent.
• Thermocouple amplifiers – Not only do thermocouple amplifiers increase the magnitude of thermocouples' typically small output signals but they can also offer additional benefits such as reducing noise, converting into linear output, and providing cold-junction compensation.
• Transducer amplifiers – After receiving the relatively weak output signals of transducers (devices that convert one form of energy into another) these amplifiers increase the magnitudes to levels that can be used for monitoring.
• Voltage-sensing amplifiers – These conditioners convert small voltage differences into logic level output signals.
• Fiber-optic amplifiers – Used to strengthen the transmission of fiber-optic communications systems, these amplifiers boost weak optical signals and can also convert them into electrical outputs.
• Strain-gauge amplifiers – After strain-gauge sensors convert force into electrical resistance, these amplifiers strengthen the signals or convert them into more useful forms.
• Capacitive-sensor amplifiers – These conditioners improve the performance of capacitive sensors by correcting nonlinearities or unwanted environmental influences.

What should you consider when choosing amplifiers for sensors?

Our selection of amplifiers is extensive, making it easy for you to find an option that suits your application. Consider the following points when searching for the right sensor amplifiers:

• Function – Your chosen amplifier will need to be compatible with the type of sensor with which you intend to use it. We offer amplifiers for the different types of sensor listed in the section above, as well as several more.
• Output – You'll need to choose an amplifier that produces a suitable output for your data processing system. We stock options that produce a variety of outputs, including analog, digital, PNP, NPN, and solid-state relay.
• Mounting type – Our sensor amplifiers come with various types of mounting brackets, allowing you to fix them in a range of positions depending on your application. We stock models that can be mounted with brackets, panels, screws, DIN rails, and more.

Use the search filters to narrow down the different options and quickly find a sensor amplifier that matches the specifications you need.
