Is there a difference between a sensor, transducer, and transmitter?
Please note that these terms are often interchanged without regard to the meaning below, and that the exact definitions may differ from source to source. AST uses these general definitions. • Sensor Lowest level of assembly. It offers mV output and can be used up to 10 to 20 feet away from electronics without significant signal loss. • Transducer Sensor with high-level voltage or frequency output with a drive capability up to 50 feet without significant signal loss. • Transmitter Sensor with current output, such as 4-20mA (Loop powered, two wire); ideal for long signal transmissions. 4-20mA also offers good EMI/RFI immunity for noisy application environments.
