Ocean Bottom Sensors

• PST— Series 海洋检波器系列 :• Features

• High output• Precise over wide range of pressure and temperature(100M 0~35·c )• Natural frequency 8Hz or 10Hz• Acceleration canceling• Easy polarity check

The PST- Series is transformer coupled and has an acceleration canceling piezoelectric ceramic (crystal) construction, have wide range high sensitive and frequency. Working deepness from 75M to 150 M, most depth in the 200M.

• The PST- Series Hydrophone is used to prospect for ocean geologic research, and the special case

design can effective prevents sea water leakage or salt fog from migrating down the cable into the body. The body is around molded polyurethane ,enhances high frequency response without parasitic resonance.

• Dual sensor for OBC Operations• 物理尺寸：（带外壳）• Length 长 度： 420m• Diameter 直 径： 75mm • Cable Diameter 电缆直径： 12.7mm

• This dual sensor gathered two PST-8C-II sensor elements in a vertical configuration and an hydrophone. The hydrophone can be either a PST-8B-8 for water depth up to 75 m or a PST-10C for 200 m water depth. The sensor is housed in an acoustically stealth shroud that is uniquely attached directly to the ocean bottom cable and is built to endure the rigors of deployment and retrieval of the OBC.
