80 GHz transmitters measurement in challenging environments

- Advertisment -

Siemens has launched a new series of 80 GHz radar transmitters with a narrow beam for flexible installations in existing vessel openings, or even non-intrusively for plastic vessels. The transmitters’ 80 GHz signal delivers robust, reliable measurements even in challenging environments such as those with vapours, condensation, turbulence, or solids.

The custom microchip technology delivers fast response. Its very high sensitivity allows it to detect even the weakest signal. The series consists of three products: Sitrans LR100 for basic measurement to 8 metres, Sitrans LR110 with communication and hazardous approvals options and range to 15 metres, and Sitrans LR120 with communication, longest range to 30 metres and optional submergence shield for flooding protection.

2-Wire loop powered with HART or optional Modbus RTU connectivity consumes very low energy and the fast start up is ideal for CSO (combined sewer overflow) applications.  Zero-metre blanking distance allows measurement right up to the sensor, thereby avoiding costly overfilling and the two millimetre accuracy enhances operational safety through precise measurement through the full range of applications.

The device is wrapped in an IP68 submersible housing, constructed of corrosion resistant PVDF.

Commissioning is achieved with the Bluetooth interface and the Sitrans mobile IQ App or the Sitrans RD150 remote display. In remote areas connected to the Sitrans RTU3030C remote terminal unit, critical data can be transmitted and remote servicing can be performed. Integrating critical level readings or process control data into operations can unlock new opportunities to react to safety concerns, analyse processes and identify areas for improvement. Users can monitor level measurements or diagnostic and maintenance information from the comfort of the control room or connect to Siemens MindSphere, the cloud based, open IoT operating system.
