In industrial environments, rotational speed plays a critical role in equipment efficiency, process stability, and predictive maintenance. This article introduces a practical LoRaWAN/RS485 integration solution based on the CZ580 speed transmitter, KC21 edge device, and ThinkLink platform, enabling fast connectivity and digital transformation of existing equipment.
1. Challenges in Industrial Speed Monitoring
Rotating equipment such as:
- Fans
- Motors
- Pumps
- Compressors
are widely used across industries.
However, many sites face a common issue:
Legacy sensors are still functional but not connected.
2. Solution Overview
Instead of replacing devices, a more efficient approach is:
Keep existing sensors + enable connectivity
Solution architecture:
CZ580 + KC21 + ThinkLink
3. CZ580 Speed Transmitter
CZ580 is a non-contact speed measurement device based on laser reflection.
Key features:
- Non-contact measurement
- 4–20mA and RS485 (Modbus-RTU) output
- Measurement range: 0–10000 RPM
- Supports low and zero speed detection
- Strong anti-interference capability
- Suitable for harsh industrial environments
4. System Architecture
Data flow:
- CZ580 → RS485 → KC21
- KC21 → data acquisition & processing
- Data → ThinkLink platform
- Platform → visualization & integration
