The Temposonics® position sensor MH for SIL2 applications is now available with analog interfaces!

MTS Systems Corporation (NASDAQ:MTSC), a leading global supplier of test systems and position sensors, announced today that the Sensors Division introduced the analog output for the magnetostrictive Temposonics® position sensor MH Safety.


The position sensors MH Safety from the MH series are approved for operation in safety-related applications. The sensors meet the requirements of Safety Integrity Level 2 (SIL2) to IEC 61508 and therewith also the requirements of Performance Level d to ISO 13849-1. This means the MTS position measurement systems are approved for safety functions on mobile machines.

Electrical stroke ranges offered from 50 mm to 2,500 mm and analog as well as digital outputs are available. The analog signals have a voltage from 0,5 to 4,5 DC und current from 4 to 20 mA, the digital signals are transferred by CANopen Safety acc. to CiA DS 304- Device profile DS-406 V3.1.

In an unlikely event of an internal sensor failure the electronic will send a failure signal to the machine controller. This enables the control system of the machine to react and stop the linear motion or set the cylinder in a safe position. This functional safety capability is required for all machines designed acc. to ISO 13849 safety standards.

Integrated diagonstics ensure the high degree of functional safety. The sensor electronics will run an internal diagnostic function. This procedure ensures that every position data is checked by internal diagnostic.

Temposonics®  MH Saftey series sensors provide a Safe Failure Fraction (SFF) of 94 % (analog outputs) and 98% for CANopen Safety protocol. This is designed for a Hardware Fault Tolerance (HFT) of 0- single channel architecture acc. to performance level d (Pld) - Cat2 acc. to ISO 13849. They are designed for a high-demand mode of operation. Due to the SIL2 classification of the sensor, this corresponds to an average probability of failure (PFH) in a range from >= 10-7 to < 10-6 per hour.

The MTS sensors support the functional safety and contribute to meet the safety requirements of the entire machine. Possible applications are a variety of utility vehicles and mobile machines that must be in accordance with the special safety requirements. These applications include steering systems of construction or agricultural machines and crane overload systems.
