NCS-TT306HR Rail-Mounted Dual-Channel HART Temperature Transmitter

NCS-TT306HR

Product Overview

NCS-TT306HR Smart Temperature Transmitter is a dual-channel rail-mounted temperature transmitter featuring high reliability, excellent long-term stability, high measurement accuracy, and low temperature drift. Equipped with advanced diagnostics and sensor redundancy with hot backup, it meets the measurement requirements of critical process stages and serves as an indispensable field temperature measurement device in process control. It supports measurements from various types of resistance temperature detectors (RTDs), thermocouples (TCs), resistors (Ω), and voltage (mV) sensors, and is compatible with the 4-20mA + HART communication protocol. The product has obtained multiple international certifications, including explosion-proof, CE-EMC, SIL, PAC, EAC, and FCG, and is widely used in process industries such as petroleum, chemical, power generation, and metallurgy.
