# MacSync-WRTDX2 Wi-Fi RTD (PT100) Temperature Sensor Datasheet

## Product Overview
**MacSync‑WRTDX2** is a high‑accuracy **Wi‑Fi–based RTD (PT100) temperature sensor** designed for industrial applications where precision, reliability, and direct IP connectivity are required. It delivers stable and accurate temperature measurements using **PT100 sensors with IEC 60751 linearization**, making it ideal for process monitoring and critical thermal applications.

Engineered for harsh industrial environments, MacSync‑WRTDX2 features a rugged enclosure with industrial‑grade electronics, surge protection, and optional IP‑rated protection suitable for pipelines, machinery, furnaces, boilers, cold‑chain systems, and manufacturing process lines.

The device transmits temperature data securely over standard **Wi‑Fi networks (2.4 GHz / 5 GHz)** to **on‑premise servers, SCADA systems, or cloud platforms** using industry‑standard protocols such as **MQTT, HTTP, and HTTPS**—without the need for gateways or long‑range wireless infrastructure.

MacSync‑WRTDX2 supports **event‑based alerts, configurable sampling intervals**, and **local BLE‑based provisioning** using the Macnman Maya mobile application. With flexible **battery‑operated or DC‑powered variants**, it is well suited for both fixed installations and locations where wired connectivity is limited.

From **industrial process control and predictive maintenance** to **HVAC monitoring, thermal safety compliance, and food & pharmaceutical temperature assurance**, **MacSync‑WRTDX2 provides accurate, low‑latency Wi‑Fi temperature monitoring** for modern industrial IoT deployments.
