Advanced Data Bulk Dielectric Transducer with Radio Telemetry The RDNET-BDT is a revolutionary micro-power state-of-the-art “bulk dielectric” sensor that can be applied to a wide range of applications where there is need to differentiate between water, dilute acidic/alkali solutions, milk and other similar relatively high permeability substances which displace or are displaced by a relatively low permeability substances such as air, oils, fats, waxes, gases, steam, etc. Applications include:
Pollution Containment Valve Automatic Activation
High Level Alarms
Oil Blanket Alarms for Oil Interceptors
High Water Alarms
Flood Alarms
FOG Blanket Alarms (Fat, oil and grease) for Fat Traps
Blocked Sewer Detection
CSO Spill Detection
The transducers are configured to operate with our integrated battery powered wireless transmitter that use DSP to converts the complex output waveform from the transducers into a simple high level, low level signal that can operate remote relay contacts for process control or to initiate an alarm. The transducers housed in a chemically inert, food safe, Acetal plastic housing that fully encapsulated to IP68 standards. Unlike traditional conductivity and float switch probes the lack of moving parts and electrical contacts makes them virtually immune from fouling and ragging.
Both the transducers and transmitters can be installed in either above or below ground locations. The latter includes drains, sewers, oil interceptors, septic tanks and fat traps. When mounted above ground, the radio telemetry can communicate over distances ranging from a hundreds of meters to many km. From below ground, depending upon the construction of the access chamber and the antenna type used, distances from a few tens of meters to up to 200m can achieved eliminating the need for messy, disruptive and costly trenching and cable ducts. The communication distance can be increased further by the use of an optional repeater. Design & Copyright Radio Data Networks Limited 2011 Issue 1.0
