Intelligent Integrated Temperature Transmitter 4-20mA 0-20mA 0-5V Output

An integrated temperature transmitter is a device that integrates a temperature sensor (such as a thermocouple or thermal resistor) and a signal transmitter into a single structure.

• Strong anti-interference ability: The output is a current signal, which is less affected by line resistance and on-site electromagnetic interference during transmission, ensuring high accuracy over long distances (up to several kilometers).
• Easy installation, cost and space saving: The integrated structure eliminates the need for connection wires and installation brackets between the sensor and the transmitter, reducing material costs and installation time.
• Good stability and high accuracy: As the signal is immediately converted and amplified on-site, the chances of signal attenuation and noise introduction are reduced, resulting in higher overall measurement accuracy.
• High safety: The 4-20mA signal is an internationally recognized safe explosion-proof signal, especially suitable for flammable and explosive hazardous environments. The integrated design also makes it easier to achieve overall explosion-proof certification (such as Ex d, Ex ia).
• Programmable capability (intelligent type): Modern integrated temperature transmitters are mostly intelligent types, allowing for remote configuration via hand-held devices or software to easily modify the measurement range, output characteristics, diagnostic information, etc., without the need for on-site calibration.

• Petrochemical industry: Temperature monitoring of reactors, pipelines and storage tanks.
• Power industry: Temperature monitoring of boilers, steam pipelines and generator sets.
• Metallurgical industry: Temperature control in blast furnaces and steel rolling processes.
• Food and pharmaceutical industry: Temperature measurement of fermentation tanks, sterilization vessels and clean pipelines.
• HVAC: Water temperature control in central air conditioning systems.
• Water treatment: Temperature monitoring in the wastewater treatment process.

• Regular Calibration: It is recommended to calibrate annually using a high-precision constant temperature bath to ensure measurement errors are within the allowable range.
• Environmental Inspection: In high-temperature environments (>85℃), heat sinks should be installed. In high-humidity environments, condensation on the sensor surface should be regularly cleaned.
• Explosion-proof Verification: In hazardous areas, the integrity of explosion-proof sealing components should be inspected every six months to prevent a decline in explosion-proof performance due to aging.

The integrated temperature transmitter is a key field instrument in modern industrial automation systems. It combines the functions of sensing and transmitting into one, and has become the preferred solution for temperature measurement in process control due to its strong anti-interference ability, high precision, ease of installation and maintenance, and other advantages.
