UNDERWATER PRESSURE SENSOR (0-5000 PSI)

SKU : 1-09-08

Tourmaline ICP omnidirectional underwater blast sensor measures shock wave pressures associated with underwater explosion testing, 19.3 cm (7.6 in.) length with 61 m (200 ft.) of 038 water tight cable terminating in a BNC plug. The sensor is structured with a volumetrically sensitive tourmaline crystal, suspended and sealed in an insulating, oil-filled vinyl tube. It has integral microelectronics. This underwater shock wave sensor provides a clean, non-resonant high-voltage output through long cables in adverse underwater environments. It contains a weight attachment hole to suspend the sensor in water at a given depth. Compatible with MREL’s DataTrap II™ Data/VOD Recorder (Product 1-04-01) and MicroTrap™ VOD/Data Recorder (Product 1-03-01) containing the optional MicroTrap™ Scope Upgrade (Product 1-03-03). Requires excitation power from Product 1-11-03A. Sensors with other maximum pressure levels are available, contact MREL for more information. The sale of this item is controlled by federal authorities – export approval must be obtained by MREL for all Customers.
