The TMT188 features a revolutionary modular design that allows users to customize input types, output signals, and housing configurations to meet specific operational requirements. It supports a wide range of temperature sensors, including RTDs (e.g., Pt100, Pt1000, Ni100), thermocouples (Types J, K, T, E, N, R, S, B, C), resistance sensors, and millivolt signals. The transmitter can accommodate up to two independent measurement channels, enabling simultaneous monitoring of multiple processes or redundant measurements for safety-critical applications. Its robust housing, available in cast aluminum or stainless steel, provides exceptional durability with an IP66/IP67 protection rating, ensuring reliable performance in harsh environments such as extreme temperatures, moisture, dust, and corrosive atmospheres. The TMT188 is certified for use in hazardous areas (ATEX, IECEx, FM, CSA) and complies with international safety standards, including SIL 2/3 for safety instrumented systems.

The TMT188 delivers outstanding measurement accuracy, with deviations as low as ±0.05% of the measured value, and offers long-term stability to minimize calibration needs. It incorporates Endress+Hauser's proprietary Heartbeat Technology, which enables continuous self-monitoring and diagnostics without interrupting the process. This feature detects potential issues such as sensor breakage, degradation, or wiring faults, providing early warnings for predictive maintenance and reducing the risk of unplanned downtime. The transmitter supports multiple communication protocols, including 4–20 mA HART, PROFIBUS PA, Foundation Fieldbus, and MODBUS RTU, ensuring seamless integration into both conventional and digital industrial automation systems. Its large, customizable LCD display shows real-time data for all channels, along with status alerts and diagnostic information. The display can be rotated 320 degrees for optimal viewing in any installation orientation.

The TMT188 is widely used in industries where precise temperature monitoring is critical for process efficiency, safety, and regulatory compliance. In pharmaceutical manufacturing, it ensures stringent temperature control in bioreactors, autoclaves, and purification systems. In the chemical and petrochemical sectors, it monitors reactor temperatures, distillation columns, and pipeline processes. In power generation, it supervises turbine systems, cooling circuits, and steam lines. The food and beverage industry relies on the TMT188 for pasteurization, sterilization, and brewing processes, where hygienic design and accuracy are paramount. Its multi-channel capability also makes it ideal for applications requiring differential temperature measurement or redundancy, such as in safety shutdown systems.

The Endress+Hauser iTEMP TMT188 stands out as a versatile, reliable, and future-proof solution for industrial temperature monitoring. Its combination of modular flexibility, advanced diagnostics, and robust construction ensures optimal performance in even the most challenging environments. By reducing maintenance needs, enhancing safety, and enabling seamless integration into digital ecosystems, the TMT188 helps industries achieve higher operational efficiency and lower total cost of ownership. Whether used in hazardous areas, high-precision processes, or complex multi-point monitoring applications, the TMT188 delivers unmatched reliability and value, making it an indispensable tool for modern industrial automation.
