What is Secondary transducer?

A secondary transducer is a device that converts a signal from a primary transducer into a different form of signal for further processing or measurement. For example, it may convert mechanical movement detected by a primary transducer into an electrical signal. Secondary transducers often enhance or modify the output of primary sensors, making them crucial in various applications such as instrumentation and control systems. They help in interpreting the data captured by primary transducers for better analysis and usability.
