Notice: We are currently performing system updates to enhance platform features and performance.
Wireless 4-20mA current loop ingestion, Modbus RTU multi-slave polling, silo fill-level tracking, and predictive maintenance telemetry for manufacturing plants and metallurgical foundries.
Explore interactive hotspots across our real-world smart manufacturing deployment architecture—from 4-20mA current-loop transducers and Modbus RTU energy meters to IP67 outdoor gateway clusters and 24/7 predictive SOC monitoring.

Analog 4-20mA Loop -> VIoT 4-20mA Radio Node
Industrial current-loop sensor measuring raw material silo levels, hydraulic line pressures, and valve positions in heavy foundry plants.
End-to-end telemetry architecture from sub-surface field sensors and low-power wireless nodes to IP67 gateways and cloud analytics.
Continuous sensing on high-temperature processing lines, raw material silos, and rotating machinery.
Deployed across a high-temperature industrial manufacturing plant to track raw material silo fill-levels, log 4-20mA analog potentiometer readings, and stream real-time telemetry to Cloud & On-Premises monitoring dashboards.

Standardized sensors and interface modules integrated into Vandyam's VIoT Gateway.
