ABB TTH300 temperature transmitter

ABB TTH300 temperature transmitter

The ABB TTH300 temperature transmitter is a high-performance industrial measurement device engineered to deliver accurate, stable temperature readings for critical process applications, making it an ideal choice for independent stations and large-scale plants alike. As a key model in ABB’s temperature transmitter lineup, it combines robust design with advanced technology, supporting universal input for RTDs (Pt100, Pt1000), thermocouples (J, K, T, E, etc.), mV, and ohm signals to adapt to diverse industrial needs. The ABB TTH300 temperature transmitter boasts a base accuracy of ±0.075% of full scale, with long-term stability of ±0.05% per year, ensuring reliable data without frequent calibration, which reduces maintenance costs and downtime.

Equipped with flexible output options, the ABB TTH300 temperature transmitter offers 4-20 mA DC with HART 7 communication as standard, enabling seamless integration with existing industrial control systems and remote monitoring capabilities. It features a compact, rugged housing made of polycarbonate (IP65 protection rating) for dust and water resistance, suitable for both indoor cabinet mounting and harsh on-site environments. The transmitter operates in a wide ambient temperature range of -40°C to +85°C, with electrical isolation of 2.5 kV DC between input, output, and power supply to prevent signal interference.

Safety and usability are core to the ABB TTH300 temperature transmitter: it is SIL 2 certified (IEC 61508) for safety-critical applications, with optional explosion protection approvals (ATEX, IECEx) for Zone 1/2 hazardous areas. It includes built-in diagnostics (wire break, overrange, and sensor fault detection) with LED indicators for quick status checks, simplifying maintenance. Configurable via HART handheld terminals, PC software, or FDT/DTM tools, the transmitter supports easy setup without extensive technical expertise. Lightweight (only 220g) and easy to install, the ABB TTH300 temperature transmitter is a cost-effective, durable solution for industries such as oil and gas, chemical processing, power generation, and water treatment, delivering consistent performance you can trust.
