MTL MTL-4073
Product introduction
The Eaton MTL MTL – 4073 is a high – precision temperature converter designed specifically for industrial applications. It is an integral part of Eaton MTL’s portfolio of industrial control and safety – related products. This converter plays a crucial role in industrial temperature monitoring and control systems.
Its core function is to accurately convert low – level DC signals from temperature sensors installed in hazardous areas into a standard 4 – 20 mA current output. This standard output is then used to drive loads in safe areas. The MTL – 4073 supports a wide range of input types, including both thermocouples and RTDs. Software – selectable features such as linearisation, ranging, monitoring, testing, and tagging are available for eight thermocouple types and 2 – , 3 – , and 4 – wire RTDs. This flexibility makes it suitable for a variety of industrial processes where precise temperature measurement and signal conversion are essential.
Core advantages and technical highlights
High – precision signal conversion
The MTL – 4073 offers an accuracy of ±0.1% of full scale. This high – level precision ensures that the temperature data converted into the 4 – 20 mA output signal is extremely reliable. In industrial processes where even a slight deviation in temperature measurement can lead to significant issues, such as in chemical reactions or food processing, this accuracy is of utmost importance. For example, in a pharmaceutical manufacturing process, maintaining the correct temperature within a narrow range is critical for product quality. The MTL – 4073 can accurately convert the temperature sensor signals, enabling precise control of the manufacturing environment.
Wide input compatibility
With support for both thermocouples and RTDs, the MTL – 4073 is highly versatile. Thermocouples are suitable for high – temperature measurements in applications like steel manufacturing or power generation, while RTDs are more precise for lower – temperature ranges, such as in food storage facilities. The ability to handle different input types makes it adaptable to various industrial scenarios. Additionally, the software – selectable features for different thermocouple types and RTD wire configurations further enhance its compatibility.
Hazard – area suitability
Designed for use in hazardous areas, the MTL – 4073 meets strict safety standards. When used with a proper cold – junction compensation method (such as the SCJ 01 hazardous – area connector for THC inputs), it ensures safe operation in environments where there may be flammable gases, vapors, or dust. This makes it an ideal choice for industries like oil and gas, where hazardous conditions are common.
Typical application scenarios
Oil and gas industry
In oil refineries and gas processing plants, the MTL – 4073 is widely used. For instance, in a crude oil distillation unit, temperature sensors are placed at various points in the distillation columns. These sensors, which could be thermocouples due to the high – temperature environment, send low – level DC signals. The MTL – 4073 converts these signals into 4 – 20 mA outputs, which are then used to control valves, pumps, and other equipment in the safe – area control room. This ensures that the temperature – sensitive distillation process is accurately monitored and controlled, preventing any potential over – heating or under – heating situations that could lead to production inefficiencies or safety hazards.
Chemical manufacturing
Chemical plants often have complex processes that require precise temperature control. In a polymerization reaction, for example, the temperature must be maintained within a very specific range to produce high – quality polymers. RTDs are used to measure the temperature inside the reaction vessel. The MTL – 4073 takes the signals from these RTDs, converts them, and sends the 4 – 20 mA output to the plant’s distributed control system (DCS). The DCS then adjusts the heating or cooling systems accordingly, thanks to the reliable signal conversion provided by the MTL – 4073.
Food and beverage production
In food and beverage manufacturing, maintaining the right temperature is crucial for product quality and safety. In a large – scale bakery, for example, the ovens need to be precisely controlled. Thermocouples are used to measure the oven temperature. The MTL – 4073 converts the thermocouple signals into a format that can be easily processed by the bakery’s control system. This allows for accurate adjustment of the oven’s heating elements, ensuring that the baked goods are cooked evenly and to the desired quality.
