Dynamic Positioning Transponder with Inclinometer

The Type 8132 Dynamic Positioning Transponder with dual-axis inclinometers (DPTi) is designed to monitor the angle of the riser flex joint on a drilling vessel.

 

 

Available with a 3,000 metre rated directional transducer, DPTi's are equipped with a simple On/Off switch, rugged spring assisted release mechanism, depth sensors and advanced power and gain controls if required.

DPTi's support Sonardyne Wideband signals, tone frequencies and all HPR 300/HiPAP® channels. DPT also supports Sonardyne command and control options.
