Introduction to PCB Piezotronics and their Signal Conditioners
PCB Piezotronics is a leading manufacturer of sensors, accelerometers, and related equipment for various industries, including automotive, aerospace, and industrial applications. The company has recently introduced a new signal conditioner designed specifically for use with DC sensors, offering enhanced performance and flexibility for users.
What are Signal Conditioners?
Signal conditioners are electronic devices that convert the output of a sensor into a form that can be easily read and interpreted by other equipment, such as data acquisition systems or control systems. They are essential components in many measurement and control applications, as they help to ensure accurate and reliable data collection.
The Importance of Signal Conditioning in Measurement Systems
Signal conditioning plays a critical role in ensuring the accuracy and reliability of measurement systems. Some of the key functions of signal conditioners include:
- Amplification: Signal conditioners can amplify low-level signals from sensors, making them easier to measure and process.
- Filtering: Signal conditioners can filter out unwanted noise and interference, improving the signal-to-noise ratio and ensuring cleaner, more accurate measurements.
- Isolation: Signal conditioners can provide electrical isolation between the sensor and the rest of the measurement system, protecting against ground loops and other sources of interference.
- Linearization: Some sensors have non-linear output characteristics, which can make it difficult to accurately interpret their readings. Signal conditioners can linearize the output of these sensors, making it easier to work with the data.
