NCS-TT105F Field-Mounted Dual-Channel FF Temperature Transmitter

NCS-TT105F

Product Overview

NCS-TT105F Smart Temperature Transmitter is a dual-channel, field-mounted temperature transmitter featuring an LCD display and button-based parameter configuration. It offers high reliability, long-term stability, measurement accuracy, and low temperature drift. Equipped with advanced diagnostics and sensor redundancy with hot-swap capabilities, it meets the measurement requirements of critical process stages, making it an indispensable field temperature measurement device for process control. It is suitable for measuring various types of resistance temperature detectors (RTD), thermocouples (TC), resistors (Ω), and voltage (mV) sensors, and supports FF communication protocol. The product has obtained multiple international certifications, including Intrinsic Safety, Flameproof, PAC, EAC, and FCG, and is widely used in process industries such as petroleum, chemicals, power, and metallurgy.
