MTL831B

The MTL831B multi-channel temperature transmitter is a widely used equipment in industries such as petroleum, chemical, power, and metallurgy, mainly used for measuring and controlling temperature changes. This product can be used in conjunction with various thermocouples and RTD sensors, outputting signals such as 4-20mA and Hart, with high precision and stability, making it an ideal choice for industrial automation control systems.

The power supply voltage range of MTL831B is DC 12-32V, with a wide temperature measurement range from -200 ℃ to+850 ℃. Its accuracy is as high as ± 0.1% FS, and the working temperature range is between -40 ℃ and+70 ℃. In terms of product specifications, the size of MTL831B is 52mm x 20mm x 114mm, with a weight of approximately 100g. The shell is made of aluminum alloy material, with a protection level of IP20. The installation method supports 35mm DIN rail installation.

In terms of application, MTL831B can form a multi-channel conversion system with MTL838B-MBF receiver and MTL3052 isolation barrier to achieve input and output signal transmission of single or double redundant line pairs, reducing the cost of laying cables in hazardous areas. In addition, it can also input signals to safe areas through the data highway, with intrinsic safety characteristics, and can be installed in hazardous areas such as Zone 0 or Class I zones.

In terms of explosion-proof and protection, MTL831B is equipped with corresponding explosion-proof and protective equipment, such as ENC8/ENC8SS and ENC83/ENC83SS. These equipment not only have explosion-proof functions, but also provide an IP67 protection level to ensure stable operation of the equipment in harsh environments.

In addition, MTL831B also has two (i.e. dual redundant) data highway outputs, with a signal and power transmission distance of up to 3 kilometers, depending on the application, cable, and noise environment. Highway cables can be wires inside simple twisted pair or twisted pair IS multi-core cables. At the other end of the data highway, the MTL838B-MBF receiver is used to translate information sent from MTL831B and provide Modbus ® Serial data output represents input and status information.

Overall, the MTL831B multi-channel temperature transmitter is a powerful, stable, and widely used industrial automation equipment. Its high precision, stability, and reliability, as well as flexible configuration and scalability, make it play an important role in industrial automation and control systems.
