New Safety Measuring Module SMM for the safe SIL-3/Performance-Level "e" load measurement for overload protection
With the long-standing know-how in force measuring technology for the highest security requirements, Müller Industrie-Elektronik currently develops the new Safety Measuring Module SMM with a security function for the load measurement for overload protection which will be accredited corresponding to the high demands of the safety standard SIL 3 according to EN 61508 and EN 62061 as well as meeting performance level "e", category 3 according to EN ISO 13849-1 in the middle of 2014. The new Safety Measuring Module SMM in combination with a safety SPS can be implemented in three different construction forms at first, depending on application.
The new Safety Measuring Module SMM can be implemented locally in a DIN-rail housing for direct switch cabinet assembly (SMM-DR) or line integrated in the measuring line in the robust field housing Unicase 2 (SMM-HD) or can be integrated into a compact force sensor (MULC) as redundant output amplifier. The circuit of the Safety Measuring Module SMM is identical for all designs. The new security module is offered with an input for a strain gauge or piezo-resistive full-bridge and two 4 .. 20 mA outputs as well as a 24 VDC input for the test function and 24 VDC supply.
By the planned three construction forms and the expected security licensings to SIL-3 and performance level "e", the new Safety Measuring Module SMM of Müller Industrie-Elektronik allows a wide application spectrum for all security relevant load measurements in the airplane technology, vehicle technology, crane technology and stage technique as well as in the offshore area.
