H/L ports are high/low pressure. Confirm primary element, static pressure and project equalizing/isolation procedures.
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.
Front 83 mm; width with radio 115 mm; depth 112 mm; Ø84 / Ø76 mm. Head body 90 mm; connection block 80 mm in drawing; port spacing and threads according to configuration.
H/L ports are high/low pressure. Confirm primary element, static pressure and project equalizing/isolation procedures.
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.
cloudLOGGER SCADA ↗Industrial instrumentation ↗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.
