Schneider Electric RTT15S-T1SA1KNAFA-M1 Temperature Transmitter

Schneider Electric RTT15S-T1SA1KNAFA-M1 is a dual‑channel I/A Series temperature transmitter that accepts input from thermocouples, RTDs, resistance (ohms), or millivolt sources and outputs a 4–20 mA/HART signal for industrial process control. Its microprocessor‑based electronics minimize ambient temperature effects to deliver high accuracy and repeatability with sensor linearization, and it supports HART protocol versions 5 and 7 (with easy‑to‑use DTMs for field configuration). An optional LCD and backlit display aid on‑site visibility, and unique optical buttons enable operation through the glass of explosion‑proof housings. Operating temperature range is −40°C to +85°C (−40°F to +185°F), making it suitable for harsh environments across oil and gas, chemical processing, power and utilities, food and beverage, and water/wastewater applications. The RTT15S also offers dual‑channel configuration and automatic self‑calibration to maintain measurement integrity over time.
