A transducer is a device that converts one form of energy into another. A signal conditioner is a device that processes an electrical signal and makes it suitable for further processing or display. While both devices involve converting signals, a transducer takes a force and creates a signal that the signal conditioner further optimizes accurate measurements in process control and instrumentation systems. Different types of transducers perform specific duties such as converting temperatures into voltage (thermocouple), pressure into an electrical signal (pressure sensors), and applied force into electrical signals (strain gauges). Signal conditioners are used to amplify the strength of signals, filter unwanted noise/frequency components, isolate signals from electrical interference, and correct signals to ensure that accurate measurements are represented.

Acromag offers signal conditioners for direct measurement of primary sensors and as intermediary signal optimization devices. Temperature transmitters and process current isolators are common signal conditioners. The rugged construction of these devices helps them perform in high-pressure environments, making them ideal for automation, monitoring, processing, and energy management.
