Products Description
This unit is used to read temperature data from multiple sensors and send it to a monitoring system. In most cases, it works together with temperature cables installed inside the material, such as grain in a silo or bulk storage.
Once powered on, it continuously scans each sensor and updates the data, allowing users to check temperature conditions on a PC or mobile device without going on site.
How It Works
In real projects, temperature is not uniform. What matters is how it changes across different positions rather than a single reading.
This unit works with multiple sensors placed at different depths or locations. By reading them one by one, it builds a more complete picture of the temperature distribution inside the monitored area.
Sensors are usually connected on a bus line. The unit polls them in sequence, reads each value, processes it briefly, and sends the data out through RS485.
Depending on the project, Ethernet or wireless transmission may also be used.
The core principle of the multi-point temperature collector is:
👉 "Sensor collection → Collector processing → Communication upload"
The specific process is as follows:
1.Temperature collection
2.Real-time temperature data of different locations are obtained through multiple temperature sensors (such as DS18B20, PT100, etc.)
3.Data conversion and processing
4.The microprocessor inside the collector converts the temperature signals (from analog to digital) Calibration
5.Data integration Data transmission
6.Upload to the upper computer or cloud platform via RS485 / Modbus / TCP, etc.
👉The essence is:
👉Transform "dispersed temperature points" into "centralized and manageable data"
