PROGNOST®-SenSim - a portable device for the simulation of sensor signals It simulates static and dynamic signals for measuring loop test routines. With PROGNOST®-SenSim, testing of machine protection systems procedures can be carried out without disassembly and reassembly of the sensors. This eliminates all associated risks, such as sensor damage or calibration issues. The defined and precise violation of real safety limit settings makes the execution of PTI (Proof Test Interval) fully compliant to IEC regulatory requirements (No manipulation of safety limits to initiate Alarms / Shutdowns / Unsafe conditions). We are happy to announce that PROGNOST®-SenSim was awarded a European Patent on May 30th, 2018.
