ENGINEERING NOTES
mH2O represents water-column pressure. For other liquids define density and level scaling; confirm probe and cable compatibility.
Figures describe family options, not all available simultaneously. Confirm range, connection, materials, power and radio for the ordered unit.
The band and radio operation must match the variant and local installation regulations.
DIMENSIONS AND MOUNTING
Front 83 mm; width with radio 115 mm; depth 112 mm; Ø84 / Ø76 mm. Reference height to connection 132 mm. Cable and probe are variable; no total length dimension.

CLOUDLOGGER SCADA INTEGRATION
Every WI sensor and module is compatible with WI-MG-STD. Sensor / I/O → wireless link → WI-MG-STD → RS-485 / Modbus RTU → PLC, RTU or cloudLOGGER SCADA. The gateway provides the family Modbus interface.
Modbus RTU is implemented on the gateway serial interface. Radio frequency and operation are verified for the installation country. If MQTT is required, it is provided at the integration layer, not claimed as a native sensor protocol.
Designed to meet Class I, Division 2. This design statement is not third-party certification; hazardous-area selection is verified against unit marking, documentation and installation conditions.
Which technical information applies to this equipment?+
The page distinguishes model-datasheet data from common platform references. Performance of the proposed variant is confirmed against its configuration and current documentation.
How should I interpret the drawing dimensions?+
Front 83 mm; width with radio 115 mm; depth 112 mm; Ø84 / Ø76 mm. Reference height to connection 132 mm. Cable and probe are variable; no total length dimension. mH2O represents water-column pressure. For other liquids define density and level scaling; confirm probe and cable compatibility.
What should I confirm before equipment selection?+
Specify the variable or signal, operating conditions, connection, power, authorized band, distance and monitoring platform. Model-specific ranges and interfaces are defined for the selected equipment.
How does it integrate with cloudLOGGER SCADA?+
Every WI sensor and module is compatible with WI-MG-STD. Sensor / I/O → wireless link → WI-MG-STD → RS-485 / Modbus RTU → PLC, RTU or cloudLOGGER SCADA. The gateway provides the family Modbus interface.
