LoRaWAN Datalogger for Vacuum Pressure
A leading refrigerator manufacturer needed centralized, real-time monitoring of vacuum pressure across multiple production lines. Their existing gauges worked well locally but lacked remote visibility and actionable data.
Macnman Technologies deployed MacSync Series RS485-to-LoRaWAN Data Loggers, which captured readings from the installed vacuum pressure gauges and transmitted them securely to the customer’s SCADA system.
This solution allowed engineers to analyze trends, detect anomalies, and trigger automated actions, all without changing the existing equipment or disrupting production.
The Challenge: Data Gaps and Delayed Action ⚠️
Even with high-quality vacuum pressure gauges installed, the manufacturer faced several operational hurdles. The goal was clear — bridge the existing RS485 gauges to a LoRaWAN network, enabling real-time monitoring, SCADA integration, and actionable insights without changing the installed equipment.
Siloed Data
Each gauge collected readings locally, with no centralized visibility across production lines.
Delayed Responses
Manual checks or periodic data downloads meant late detection of anomalies, risking equipment or product quality.
Limited Integration
Existing gauges were not connected to SCADA, making automated analysis and action impossible
Maintenance Complexity
Without remote monitoring, engineers had to physically inspect each gauge, increasing labor and downtime.
