Astrafield builds industrial sensing and telemetry systems for process, water and district-energy operators. We handle the whole chain — instrument selection, field wiring, gateway firmware, and the historian your engineers actually read in the morning.
Discuss a projectSmall, senior teams. We take responsibility for the measurement, not just the dashboard.
Sensor selection, installation drawings and loop diagrams for vibration, temperature, flow, pressure and power-quality measurement.
Gateway firmware bridging Modbus RTU/TCP, OPC UA, HART and M-Bus to a hardened MQTT uplink with local store-and-forward.
Time-series storage, alarm shelving, drift detection and reporting that survives audit. Deployed on your infrastructure or ours.
On-site loop checks, calibration records and handover documentation. We stay through the first maintenance cycle.
Assessment of legacy panels and PLCs, with a staged migration plan that keeps the line running.
Named engineer, defined response windows, spare-part pool and annual re-calibration scheduling.
Our AF-series gateways are the piece most clients ask about first.
| Model | Inputs | Uplink | Environment |
|---|---|---|---|
| AF-120 | 8 × analogue, 4 × digital | Ethernet / LTE-M | DIN rail, −20…+60 °C |
| AF-240 | 16 × analogue, 8 × digital, RS-485 | Ethernet / LTE-M | DIN rail, −30…+70 °C |
| AF-310-Ex | 12 × intrinsically safe | Fibre | Zone 1, IP66 |
Fifteen years of installations across northern Europe.
