Subsea positioning solutions released by Alliance Sensors

H. G. Schaevitz LLC, Alliance Sensors, announces its SSx-7 series of LVIT subsea position sensors. Available in full scale ranges from as short as 1 inch (25 mm) up to 36 inches (900 mm), these devices are constructed of AISI 316 stainless steel to operate at depths of 10,000 feet (3,000 meters). The SSx-7 body style easily fits into an SAE O-ring port in the end of a hydraulic cylinder and is terminated with the popular micro-circular subsea connector. Offered with common analog voltage or current loop outputs, standard SSx-7 series position sensors are good solutions for many subsea applications like:

• Choke actuators in a PBOF environment
• BOP sealing or shearing ram positions
• Annular BOP seal compression piston 
• ROV electric and hydraulic actuators
• Hydraulic cylinder position sensing 

Nevertheless, because some subsea position measurements may require a customized sensor to meet application-specific requirements. ASG offers short run sensor customization typically involving one or more of the following attributes:

• Materials and seals for high pressures and/or PBOF operations
• Compatibility with non-flammable EHC fluids like phosphate esters
• Popular standard or special high pressure subsea connectors
• Alternate analog I/Os or customer-specific digital outputs over an RS-485 bus
• Simplified designs for higher reliability
