All it takes for environmental research Diver-NETZ - Mobile Schlumberger Water Services
2 Diver-NETZ - Mobile Diver-DXT < 500 m Bluetooth Smartphone file-server GPRS Diver-Gate(M)
3 Components Diver-NETZ Diver-DXT (with cable and Diver): Short range radio (500 m LOS) Build-in baro data logger Battery life >5 years
4 Specification Diver-DXT Main specs: High heat ABS Protection is IP68 Build-in battery Replaceable battery (following instructions) Build in baro sensor Accuracy 1 cmH 2 O (typ) Memory records Automatic sync. with Diver Cable length up to 300 m Radio frequency is 2.4 GHz Wake-up every 14 sec. Radio range 500 m LOS Compliant to CE and FCC
5 Components Diver-NETZ Diver-Gate(M) for mobile use: Bluetooth interface between DXT and mobile phone or PDA Internal antennas Rechargeable battery (10 hrs)
6 Specification Diver-Gate(M) Small (pocket size) device. Removable rubber guard protect against environmental conditions. Operating temperature -20ºC to +60ºC. Build-in Short Range Radio for communication with Diver-DXT. Radio range 500 m (LOS). Radio frequency 2.4 GHz. Internal antenna. Build-in Bluetooth interface for communication with Smartphone. BT Radio range 10 m. Internal antenna. Build-in rechargeable Li-ion battery. Fully charged battery for 10 hours use. (Continuous) charging through USB connection.
7 Components Diver-NETZ Diver-Mobile: For windows Mobile 6.0 Automatic data read Send data to ftp-server (option)
8 Workflow Diver-NETZ (Diver-Mobile) Bluetooth connection with Smartphone (20 sec). Diver-Mobile gives instruction to Diver-Gate(M) to search for Diver- DXTs (30 sec). The data of the selected locations are collected (5 to 60 sec). The data base is updated. The files (*.dat-files) are transmitted to the ftp-server (1-3 min). Files can be read by Diver-Office (Premium) and uploaded to website
9 Radio Range to Diver-DXT Radio Range is 500 m (LOS). This is under good conditions!!! Radio Range is negative affected by: Obstacles which interfere Line Of Sight (LOS). Obstacles can be anything like vegetation (plants/trees), buildings, cars etc. Metal close to the Diver-DXT or Diver-Gate antenna. Examples are metal well cover, car/truck etc. Position of antennas (the higher the better). Examples are Diver-DXT under ground level or on ground level. Weather conditions (fog, rain, snow etc). Flooding conditions. Diver-DXT under water (or snow/ice)
10 Radio Range to Diver-DXT Street cover: Diver-DXT is under ground level. Radio distance LOS 100 m. Radio distance around corner 20 m. Metal casing: Diver-DXT is 1 m above ground level. Radio distance LOS 200 m. Plastic casing: Diver-DXT is 1 m above ground level but with vegetation. Radio distance LOS 200 m.
