Custom Submersible Pin Load Cell Bespoke Underwater Load Cell

The PLCB bespoke pin load cell is a precision-engineered force measurement solution designed to operate reliably in some of the most challenging subsea environments on the planet. Manufactured from high-grade stainless steel and hermetically sealed, this rugged sensor is purpose-built for deepwater applications where durability, accuracy, and long-term stability are critical. Originally designed for underwater operations up to 1000 meters, the PLCB can be specified with enhanced waterproof sealing to withstand extreme subsea pressures at depths of up to 4000 meters, making it suitable for a wide variety of offshore, marine, and oceanographic projects.

The core design of the PLCB combines robust mechanical construction with advanced sealing techniques to ensure that internal electronics remain completely protected against water ingress, salt corrosion, and pressure-induced deformation. An integrated underwater connector ensures secure, reliable data transmission even in harsh subsea conditions, supporting continuous monitoring without signal degradation.

Every PLCB pin load cell is built to order, allowing customers to define critical parameters that meet their exact application needs. Customizable options include size and geometry to suit specific mechanical interfaces, measuring ranges up to 200 tonnes for both tension and compression loads, and multiple electrical output formats such as mV/V, 0–5 V, 0–10 V, 4–20 mA, or RS485 for digital communication. This flexibility ensures seamless integration into existing subsea data acquisition and control systems.

Designed to perform in a wide thermal envelope, the PLCB supports operational temperatures from –40 °C to +150 °C, making it suitable for use in both polar exploration and high-temperature subsea environments near geothermal vents. For applications that demand the highest possible resistance to extreme water pressure, enhanced IP-rated waterproof sealing is available to maintain sensor integrity and performance even at 4000 meters below the surface.

Typical uses of the bespoke PLCB subsea pin load cell include mooring line monitoring, winch and crane load measurement, ROV tooling force feedback, underwater structural testing, and other critical load monitoring tasks in deepwater engineering. By combining precision engineering, deepwater sealing expertise, and full customization capabilities, the PLCB bespoke pin load cell offers a dependable and versatile solution for subsea force measurement where failure is not an option.
