Product Overview
Real-time temperature visibility. Built for factories, warehouses, and industrial automation systems.
Looking for a reliable industrial LED temperature display that integrates directly with your PLC, SCADA, or BMS? The AT-TMT-T from ATPro Corp delivers large-digit clarity, wide temperature range, and optional Modbus RTU RS485 communication—purpose-built for demanding industrial environments.
The Problem with Manual Temperature Monitoring
In manufacturing plants, cold storage facilities, and large warehouses, temperature is a mission-critical variable. Undetected temperature deviations can lead to:
- Product spoilage in food and pharmaceutical storage
- Quality failures on production lines with heat-sensitive processes
- Equipment damage caused by unmonitored thermal stress
- Compliance failures in regulated environments such as cleanrooms and labs
Handheld thermometers require constant manual checks, introduce human error, and offer no real-time visibility to floor personnel or remote managers. The result? Delayed responses, preventable losses, and operational risk.
The Solution: AT-TMT-T Industrial LED Temperature Display
The AT-TMT-T is a robust, industrial-grade LED temperature display engineered for clear, continuous, and automated temperature monitoring. Featuring 2.3-inch high-brightness LED digits readable from up to 20 meters, it puts critical temperature data in plain sight—exactly where your workers and supervisors need it.
Equipped with an optional RS485 Modbus RTU communication port, the AT-TMT-T can seamlessly feed live temperature data into your PLC, SCADA system, BMS, or data logger—transforming a simple display into a powerful node in your industrial monitoring network.
Key Features & Benefits
🔴 Large 2.3-Inch 3-Digit LED Display
Exceptional visibility from up to 20 meters away. High-brightness LEDs ensure readability in bright factory lighting, outdoor-facing installations, or low-light warehouse environments. Available in Red (default), Amber, Green, or Blue.
🌡️ Wide Temperature Range: -40°C to +125°C
From deep-freeze cold storage at -40°C to high-heat industrial production lines at +125°C, the AT-TMT-T covers the full spectrum of industrial environments without compromise.
📐 High Accuracy: ±1°C / 0.1°C Resolution
Precise, repeatable temperature readings support quality control, regulatory compliance, and process optimization. A 0.1°C resolution means no data is left on the table.
🔌 Optional RS485 Modbus RTU Communication
Connect to any Modbus-compatible PLC, SCADA, MES, or BMS for centralized remote monitoring, historical data logging, and automated alerts. This is the feature that transforms a passive display into an active monitoring instrument.
🏗️ Durable Aluminum Alloy Frame
The black aluminum alloy frame with high-quality acrylic front panel is built to withstand vibration, dust, and the rigors of continuous industrial operation.
⚡ Universal Power Supply: 100–240V AC
Works globally with included interchangeable plug adapters (US/EU/UK/AU). Single SKU for worldwide distribution.
🔧 Easy Wall-Mount Installation
Mounts quickly on walls, pillars, or near control panels. No specialist tools required. Designed for fast deployment at scale across large facilities.
💡 Energy-Efficient LED Technology
Low power consumption makes the AT-TMT-T cost-effective for 24/7 continuous operation—even when deployed across dozens of monitoring points.
Software & Remote Monitoring Capabilities
When paired with ATPro's monitoring software or integrated into a third-party SCADA/BMS platform via Modbus RTU, the AT-TMT-T unlocks a full suite of digital capabilities:
📱 Remote Monitoring View live temperature readings from any location via PC or smartphone. Ideal for managers overseeing multiple sites or facilities. For environments requiring both temperature and humidity monitoring, the Industrial Temperature & Humidity Display can be deployed alongside the AT-TMT-T to provide a more comprehensive environmental monitoring solution.
📊 Historical Data Logging Record temperature trends over time. Generate audit-ready reports for regulatory compliance, quality management, or process analysis.
⚠️ Smart Threshold Alerts Configure automatic alerts via email or SMS when temperature exceeds or drops below defined safe ranges. Catch issues before they become failures.
🔗 System Integration System Integration Feed real-time temperature data into existing SCADA, MES, ERP, or building management systems via standard Modbus RTU protocol. For long-distance installations where wiring is difficult or costly, the AT-RS485 LoRa Converter enables wireless transmission of Modbus RTU data between temperature monitoring points and central control systems.
