What is a Digital Transmitter and Why Use It?

What is a Digital Transmitter?

A Digital Transmitter is an intelligent device that takes an analog signal from a sensor (loadcell, temperature probe, etc.), processes it with its onboard microprocessor, and converts it into digital data (Modbus, Profinet, etc.). While traditional analog transmitters only amplify the signal (like an amp), digital transmitters "interpret and clean" it.

How Does It Differ From Analog?

• Zero Noise: Analog signals can pick up noise along the cable. Digital signals (0s and 1s) are immune to noise.
• High Precision: Digital transmitters digitize the signal at the source with 24-bit resolution. You don't have to rely on the PLC's analog input card (usually 12-16 bits).
• Remote Configuration: You don't need to go to the device for calibration; you can perform "zeroing" remotely via software.
