Characteristics of split type temperature transmitter
1. Split type, strong universality
2. Two line system with 4-20mA output. Long transmission distance and strong anti-interference ability; Cold end, temperature drift, non-linear automatic compensation;

3. Mechanical protection: IP65； Using thermocouple temperature change can eliminate the need for compensating wires and reduce costs;

4. High measurement accuracy and good long-term stability; When the on-site ambient temperature is above 70 ℃, the transmitter and on-site display instrument can be installed separately (isolated);

5. The temperature module adopts epoxy resin casting technology internally, which is suitable for use in various harsh and dangerous places;
6. Integrated design, simple and reasonable structure, can directly replace ordinary assembled thermocouples and thermistors; Various indication functions such as LCD, digital tube, pointer, etc. facilitate timely monitoring on site;

7. Protection level: IP54； Explosion proof grade: dIIBT4、dIIBT5

Selection method of split type temperature transmitter

Split type temperature transmitter is an updated product for temperature measurement and control in modern industrial sites and research institutes. It is an essential product for distributed systems and digital bus systems. Jiangsu Zhongneng Instrument Technology Co., Ltd. combines sensors and transmitters into a modular temperature transmitter, which converts temperature signals within the range of -200-1600 ℃ into a two-wire 4-20mA electrical signal in a very simple way and transmits it to display instruments, regulators, recorders, DCS, etc., achieving accurate temperature measurement and control.
