Proven, retrofit Sludge Blanket Monitoring systems from 1 to 32 bridges per base station. Compete turnkey from sensor to bespoke cranked hand-rail bracket kits.
Yes unlike other suppliers, we at Radio Data Networks offer a total 100% design and delivery service from the sourcing / integration of sensors through to the complete design and fabrication of bespoke bracket sets to enable the rapid and non-disruptive mounting onto existing rotation bridges and eliminate the need for installing expensive slip rings on the bridges.
Easy to retrofit to existing lagoons, systems can be mains, battery or even solar powered and interfaced to a wide range of sludge blanket sensors. Where power does not exist the systems can be operated from batteries and the sensors automatically woken up to take regular readings. All systems include regular health messages and the receivers provide fully isolated volt-free contacts (gold contacts) designed to interface with telemetry outstations and PLC controllers.
Features include the choice of licenced and licence free radio, 110V, 240V, 12V or 24V dc operation. Battery or Battery plus solar. Units can be built with internal antenna and communications distances between bridges and control rooms of between 500m to 5km are typical.
Base Station Gateways can also accept other telemetry signals

Example of a Bespoke System Installed at a Leading UK utility Company:
The system comprises of 8 x bridge mounted rotation monitoring units connected to Partec 8100 sludge blanket monitoring units. The units are housed in bespoke rail mounted enclosures as per the illustration below.
Each of the units have the ability to transmit data (broadcast) at nominal 1-minute rates over a licenced radio channel to an 8-way Radio Data Networks modular Gateway Receiver.
