- Input and Output: The input types include thermocouples, resistance temperature detectors (RTDs), or standard resistors. The input range can be selected between -100℃ and +1000℃ depending on different models. The output is a standard 4~20mA analog signal, which can be connected to on-site digital displays, PLCs, and other equipment, with a load capacity of ≤600Ω.
- Accuracy Index: The accuracy is typically ±0.5℃ (at 25℃), and the long-term temperature stability is ≤0.1℃/year. It is equipped with a high-precision cold-junction compensation circuit, and the absolute error over the full temperature range is ±0.5℃ (±0.8℃ for S-type thermocouples).
- Operating Power Supply: It adopts DC power supply, with a default voltage of 24V DC and an allowable range of 22V~26V. The maximum power consumption is 1.2W.
- Operating Environment: The operating temperature of the transmitter circuit is -40℃~+60℃. The default operating temperature of the probe is -40℃~+80℃, which can be extended to -40℃~+120℃. The environmental humidity requirement is 5% RH~95% (at 25℃) without condensation, and the protection level can reach IP65.
- Explosion-Proof Characteristics: The explosion-proof mark is Ex ib IIB T6 Gb/Ex ibD A21 IP65 T80℃. It is suitable for explosive gas environments (excluding coal mines prone to gas) and combustible gas-dust environments.
- Other Features: It adopts a standard industrial interface for easy installation, is equipped with a dedicated analog circuit, and has a wide application range and complete specifications.
In addition, the MTL3073 is a single-channel device, which uses a DIN rail mounting method and has fixed terminals. Configuration settings can be performed via a CNF41-type handheld communicator or software such as PCS45.
