Experience the difference with the SM100-M-32 HART Data Collector—where cutting-edge technology meets industrial reliability
The HART protocol utilizes the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on top of a 4 to 20 mA base. This enables HART protocol instruments to maintain bidirectional data communication without interfering with the 4 to 20 mA analog signal. The SM100-M series HART data collector serves as an intelligent converter designed for the precise bidirectional modulation and demodulation of these digital and analog signals.
