Key Features • 3,000 or 7,000 metre depth rating • Omni, Directional or Super Directional transducers • Incorporates Sonardyne’s latest Wideband™ Technology • Multiple operating modes; tone burst and wideband • Hundreds of operating channels allowing truly independent acoustic operations • Highly reliable release mechanism • Standard Sensors - depth & temperature • Easy to set-up and test using PC software, PTT or DTU • Responder Operation • Accepts external DC power DPTs support Sonardyne Wideband™ signals, tone frequencies and all HPR 300/HiPAP® channels. DPT also supports Sonardyne command and control options. • Long battery life • Midi housing option available (Type 8129) Available in 3,000 metre rated omnidirectional or directional transducers, DPTs are equipped with a rugged spring assisted release mechanism, depth sensors and advanced power and gain controls if required. For deep-water towfish tracking, the Type 8129 DPT is a midi-sized unit with a high power super directional transducer that is depth rated to 7,000 metres. Also available is the Type 8132 DPTi which is fitted with internal inclinometers to accurately monitor riser angles (see separate datasheet). The DPTi can also be used with an external inclinometer unit to monitor flex joint angles. Sonardyne UK (Head Office) T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E. sales@sonardyne.com www.sonardyne.com Specifications Dynamic Positioning Transponder (DPT) Feature Feature Depth Rating Operating Frequency Transducer Beamshape Transmit Source Level (dB re 1µPa @ 1m) Receive Sensitivity (dB re 1µPa) Relative Positioning Accuracy* Number of Unique Addresses (Wideband) Number of Unique Addresses (Tone) Battery Life (Listening, Disabled) Dimensions (LxDia) Weight In Air Weight in Water Temperature Sensor (±0.1°C) Tilt Switch Sensor (±30-45°) Strain Gauge Pressure Sensor (±0.1%) Release Mechanism Safe Working Load (4:1) 8124 Type 8124 3,000 Metres MF (18–36kHz) Omni-Directional (±130°) 184-193dB (3 Levels) 90-125dB (4 Levels) ±5cm 224 All Sonardyne/Simrad 833 days (Alkaline) 1390 days (Lithium) 1035mm x 135mm 22.8kg 11.6kg Standard Standard Standard Standard 250kg 8126 Type 8126 3,000 Metres MF (18–36kHz) Directional (±35°) 194-204dB (3 Levels) 85-130dB (4 Levels) ±5cm 224 All Sonardyne/Simrad 833 days (Alkaline) 1390 days (Lithium) 1005mm x 135mm 22.8kg 11.6kg Standard Standard Standard Standard 250kg 8129 Type 8129 (Midi) 7,000 Metres MF (18–36kHz) Directional (±20°) 195-207dB (3 Levels) 80-120dB (4 Levels) ±5cm 224 All Sonardyne/Simrad 417 days (Lithium) 755 x 135mm tba tba Standard Standard Standard Fitted or not fitted 250kg (Where fitted) *Using Wideband acoustics.
