Performance Features and Design of HT1200M
The HART protocol superimposes audio digital signals on 4~20 mA analog signals. The digital signal amplitude is 0.5 mA and the data rate reaches 1200 b/s. 1200 Hz represents logic "1" and 2200 Hz represents logic "0". Enables two-way digital communication. HART communication has the characteristics of simultaneous point-to-point 4 ~ 20 mA analog and digital communication, multi-station communication methods, and multiple transmissions.The HT1200M is compatible with the SYM20C15 and HT20C15 and with ON OnSemi's A5191HRT and HT2015.

Analysis of the common faults and solutions of temperature transmitters
Temperature transmitter technology has been very mature, very common in various factories, transmitters are often used in conjunction with a number of instruments, often in the process of supporting the use of some minor failures. The more common faults and solutions are as follows.
