Custom IP68 Waterproof Pin Load Cell For Offshore Applications

The PLCA waterproof pin load cell is a compact, high-precision force measurement sensor engineered to deliver accurate and reliable performance in the most demanding industrial environments. Manufactured from premium-grade stainless steel, the PLCA is built to withstand harsh mechanical stresses, corrosive atmospheres, and long-term operational fatigue. Its rugged construction and IP68-rated hermetic sealing ensure complete protection against dust, water ingress, and chemicals, making it ideal for both outdoor and submerged applications.

This pin-type load cell is designed using shear force sensing technology, which allows it to provide highly repeatable and stable readings even under dynamic or fluctuating loads. Standard models are available in rated capacities of 3kN, 5kN, 10kN, and 20kN, with extended ranges up to 200 tons available on request. Thanks to its compact profile, the PLCA fits seamlessly into space-limited installations without compromising measurement accuracy or structural integrity.
The PLCA load pin is a versatile force monitoring solution suited for a wide range of industries. Common applications include:

• Tension monitoring in pulley and sheave systems for cranes, elevators, and hoisting equipment.
• Winch and hoist overload detection to enhance operational safety.
• Anchor and mooring line force measurement in offshore vessels and floating platforms.
• Structural load monitoring in bridges, tunnels, and construction machinery.
• Robotic arm joint force feedback for precision automation and control.
• Factory automation and press force control in industrial production lines.

LCS Tech Co., Limited offers extensive customization options to meet the unique needs of complex projects. Clients can specify:

• Custom dimensions, including non-standard pin diameters, lengths, and mounting holes.
• Specific mechanical interfaces such as clevis ends, threaded attachments, or recessed shoulders.
• Integrated signal conditioning, including built-in amplifiers and connectors.
• Cable outlet customization, including axial, radial, or underwater-rated routing.
• Environmental enhancements, like corrosion-resistant coatings or double sealing for chemically aggressive settings.

Electrically, the PLCA is compatible with a variety of output formats to match your system's requirements, including mV/V, 0–5V, 0–10V, 4–20mA, and RS485 Modbus RTU. The operating temperature range can be extended from -40°C to +150°C, and the sensor can be configured for deep-sea applications at depths up to 3000 meters, making it suitable for subsea cable tension control, underwater ROVs, and offshore structural monitoring.
Whether you need a robust off-the-shelf load pin or a fully customized sensing solution, the PLCA IP68 hermetically sealed pin-type load cell offers the performance, durability, and adaptability required to meet today's toughest force measurement challenges.
