Position sensor suits SIL 2 applications
Temposonics reports that its absolute, non-contact M-series position sensors are now approved for operation in safety-related applications. The sensors meet the requirements of Safety Integrity Level 2 (SIL2) as per EN 61508 and the requirements of Performance Level d of EN 13849-1. This means the MTS position measurement systems are approved for safety functions on certain mobile and stationary machines. Measuring lengths from 50mm to 2500mm are available.This high degree of functional safety is ensured by built-in diagnostic functions. In the sensor head, signals are checked and changes are detected immediately. The transducer transmits the position value to the control system only after the diagnostic test. In this way, Temposonics sensors provide a Safe Failure Fraction (SFF) of 95 per cent at a Hardware Fault Tolerance (HFT) of 0. They are designed for a high-demand mode of operation.
Designed for safety-related applications, the MTS sensors support functional safety and contribute to meeting the safety targets of the entire machine. Possible applications are a variety of utility vehicles that must be in accordance with the special safety requirements. In the field of mobile hydraulics, these applications include steering systems of construction or agricultural machines and crane overload systems.
