Cold Junction Compensation and Linearization: Each input channel can receive variable voltage signals, perform thermocouple linearization and cold junction compensation, convert the results into Celsius or Fahrenheit, and then transmit a 16-bit signed integer representing the temperature to the main processor.

User-Friendly: Supports plug-and-play, requiring no complex configuration, facilitating installation and replacement. It also features a hot standby function, allowing online replacement of faulty modules.

Extraction and Gathering Links: Used to monitor temperature parameters of drilling platforms, oil pipelines, separators, and other equipment. For example, in the process of crude oil extraction, by collecting temperature signals of wellhead devices and heating furnaces, it ensures that the equipment operates within a safe temperature range, avoiding risks such as leakage and explosion caused by overheating.

Refining Process: In key equipment such as distillation towers, reactors, and heat exchangers, real-time monitoring of material reaction temperatures provides data support for safety interlocking systems (such as ESD emergency shutdown systems), ensuring the stability and safety of the refining process.

Chemical Reaction Process: In chemical synthesis, pharmaceutical fermentation, and other processes, thermocouple signals directly reflect the temperature changes in the reaction kettle. The 3708E module collects these signals with high precision to ensure that the reaction temperature is controlled within the process requirements, avoiding reaction out of control, unqualified products, or safety accidents caused by abnormal temperatures.

Hazardous Material Storage: Used to monitor the ambient temperature and material temperature in storage tanks, warehouses, and other areas. In conjunction with fire and gas monitoring systems (F&G), it timely warns of high-temperature hazards, preventing flammable and explosive chemicals from causing fires or explosions due to excessive temperatures.

Thermal Power Generation: In equipment such as boilers, steam turbines, and superheaters, collect temperature signals of high-temperature flue gas, steam, and metal walls to real-time monitor the operating status of the equipment. For example, excessive temperature of boiler tube walls may lead to tube bursting, and the high-precision measurement of the 3708E module can provide early warning to ensure the safe and stable operation of the generator set.

Nuclear Power Auxiliary Systems: In non-nuclear safety loops of nuclear power plants (such as cooling systems and pump equipment), used to monitor temperature parameters of pipelines and containers, meeting the strict requirements of the nuclear power industry for equipment reliability and safety (such as 10CFR50 and other standards).

Smelting Process: In equipment such as blast furnaces, converters, and rolling mills, collect temperature signals of furnace chambers, molten steel, and rolls, providing key data for smelting process control. For example, the accurate monitoring of steel plate temperature during rolling directly affects product quality, and the anti-interference ability of the 3708E module can ensure measurement stability in high-temperature and strong electromagnetic environments.

Heat Treatment Process: In annealing furnaces, quenching equipment, real-time monitoring of material temperature changes to ensure that heat treatment process parameters meet standards, and preventing equipment damage due to overheating through safety interlocking logic.

Gas Turbines and Steam Turbines: Used to monitor temperatures of key parts such as combustion chambers, blades, and exhaust systems of the units, avoiding equipment failures caused by local overheating, and ensuring the continuous operation of power generation or driving equipment.

Solar Thermal Power Generation: In concentrating solar power systems, monitor the temperature of heat absorbers and heat transfer fluids, ensuring the efficiency of photothermal conversion while preventing damage to equipment due to overheating.

Aerospace Ground Test Facilities: In engine test benches, high-temperature simulation chambers, and other scenarios, collect thermocouple signals in extreme temperature environments to provide data support for test safety control.

Large Industrial Furnaces: Such as glass kilns, cement rotary kilns, monitor the temperature distribution in the furnace chamber to ensure stable production processes, and prevent furnace damage or fire risks through temperature abnormality early warning.
