Product Overview
The AT-TMS3.1 is an industrial temperature display designed for data centers, server rooms, cold storage, pharmacies and manufacturing facilities.
It combines a bright 6-digit LED display, RS485 Modbus RTU communication, one relay output and a remote temperature sensor with a cable distance of up to 20 meters.
When connected to ATSCADA, users can monitor temperature remotely, review historical trends and receive alarm notifications.
Application in Data Centers
Show the AT-TMS3.1 installed at the end of an aisle between server racks in a modern data center.
The bright LED display allows facility teams to check real-time temperature from a distance without opening control cabinets or checking each rack manually.
The Problem
High temperature can reduce server performance, shorten equipment life and cause unexpected shutdowns.
Manual inspections only provide temperature readings at the time of inspection. They cannot continuously detect rising temperatures or immediately notify staff when a limit is exceeded.
Data centers therefore need continuous temperature monitoring with local display, remote access and automatic alarms.
The Solution – AT-TMS3.1
The AT-TMS3.1 provides continuous temperature monitoring in server rooms and other critical environments.
Its high-brightness LED display shows the current temperature clearly. The remote sensor can be installed up to 20 meters from the display, providing flexible sensor placement inside racks, cold rooms or storage areas.
The device communicates with PLC, SCADA and BMS systems through RS485 Modbus RTU.
Its built-in relay can automatically activate:
- Cooling fans
- Warning lights
- Audible alarms
- Backup cooling systems
- Refrigeration control equipment
Dual-Color Status Alert
The display uses clear color indicators to help operators identify system status quickly:
-
Green: The temperature remains within the configured range.
-
Red: The temperature exceeds the configured alarm threshold.
The bright color-changing display keeps readings clearly visible in industrial environments, similar to large-format temperature humidity displays.
