The temperature of the industrial site is input to 305X through thermal resistance or thermocouple sensor, and converted into corresponding temperature measurement value by microprocessor after "analog-digital conversion". Then the microprocessor sends the measured value to the highlight LCD for real-time display, and is proportionally converted into a corresponding 4-20mA current signal output through "digital-analog conversion". At the same time, the transmitter information (including measured values, diagnostic information, etc.) can be read in real time through HART communication, or the transmitter can be debugged.
The temperature of the industrial site is input to the 303X through thermal resistance or thermocouple sensors, and after "analog digital conversion", it is converted into the corresponding digital quantity by the microprocessor. The digitized temperature value is sent to the highlighted LCD for real-time display, and can also be transmitted to the main control equipment through the RS485 bus. The RS485 protocol allows for convenient remote parameter setting and debugging of the transmitter.
