Written by the engineers who build and deploy these systems - practical guides on industrial sensor hardware, monitoring architecture, and the business case for real-time visibility in South African facilities.
4-20mA current loops are the dominant sensor standard in industrial facilities for good reason - they resist electrical noise, detect broken wires automatically, and travel long cable runs reliably. Here is how to wire them correctly in environments that will do their best to break them.
Read ArticleSCADA systems were designed for large process plants - oil refineries, utilities, water treatment facilities - where tight PLC integration and certified safety systems justify the cost. For small-to-medium facilities, IIoT offers faster deployment, lower cost, and mobile access without the SCADA overhead.
Read ArticleProcurement asks for ROI. The honest answer is that monitoring ROI is mostly negative expected value from prevented incidents - not a positive return from productive output. Here is how to calculate it correctly and present it in terms that resonate with a procurement committee.
