MTS Systems Corp., Sensors Division has developed a new Temposonics Model MH sensor, marketed as the SIL2 with analog output or Can Safety interface, that meets industry safety standards required in high risk applications such as crane and fire engine outrigger controls.
The Model MH sensor is available for use with both analog signal and CAN Safety protocols that meet the requirements of Safety Integrity Level 2 (SIL2) under IEC 61508 and Performance Level d of ISO 13849-1. These requirements ensure that communication between the sensor and the electronic controller is accurate and unaffected by external influences. This is especially critical in high-precision applications, such as outriggers, where even the smallest deviation can be devastating.
“There is no room for error in these applications,” Haubold “Hub” vom Berg, Technical Market Manager for Mobile Hydraulics at MTS, explains. “Machine operators have to be able to trust that data on the controller accurately to reflect the position of the hydraulic cylinders on the equipment. These new sensors are among the most accurate and reliable in the industry.”
The new MH sensors achieve this through advanced built-in diagnostic functions. Prior to communicating with the controller, signals are continually checked within the sensor head and changes are detected instantly. The position of the hydraulic cylinder is only transmitted after this safety backup feature confirms data is accurate.
“By integrating these sensors into the hydraulic cylinders during their equipment design, OEMs can improve performance and reduce the likelihood of catastrophic failures in the field,” vom Berg says. “Our goal is to give them the tools they need to produce the safest machinery possible.”
Developed specifically for mobile hydraulic applications, M-Series Temposonics Sensors are used integrated into hydraulic cylinders on mobile equipment where accurate control and measurement, as well as resistance to the elements and shock are needed. These products meet ISO14982 standards for agricultural and forest machines and ISO7637-0/1/2 standards for road vehicles. They are typically embedded inside a hydraulic cylinder to provide better resistance to environmental factors.
