Redundant load cells

About the product

Customer-specific redundant load cells, load pins, force transducers and torque sensors in cases where it is desired to measure the same deformation, multiple channels.

To improve measurement reliability or to better suit the application, it may be useful, or even mandatory, to obtain redundant measurement channels by using several additional

Examples

• Long-term unavailability underwater power transducer with 2 Wheatstone bridges, 2 amplifiers and 2 cables to create a back-up (second) channel in case the first one fails.
• SIL3 (IEC/EN 61508) certified handling system including a load pin with 2 amplified Wheatstone bridges (4-20 mA) connected to a safety PLC that continuously checks the consistency of both of these signals.
• Load cell with 3 channels: one connected to overload protection electronics, the second to a PLC and the third to a data logger.
• Torque sensor with analog signal (4-20 mA) for connection to local PLC and digital signal (RS-485) for connection to fieldbus.

Therefore, among the many available options, load cells, load pins, force transducers or torque sensors, all with multiple redundant measurement channels guaranteeing higher levels of safety and reliability. This new complex architecture meets the new safety and security requirements required for modern force measurement and control systems.
