Machine data NEA (Neumann Esser) horizontal reciprocating compressor with 4 throws. 1 stage in Natural gas service. The Pressure for Inlet is 33 bar (479 psi) for Outlet 75 bar (1088 psi). NEA horizontal reciprocating compressor Used Monitoring Software Modules of PROGNOST®-NT Machine Protection Early Failure Detection Wear Monitoring Performance Optimization Process Data Integration Sequence of events PROGNOST Systems received a call from the customer. The compressor was shut down by the PROGNOST system shortly after start up. This was a result of protection limit violations on two measuring points. In detail the shutdown was triggered by increased vibrations at the crosshead guides 3 and 4, this affected segment 20 of crosshead slide (CHS) 3 and segment 19 [...]

Sensor simulation device PROGNOST®-SenSim patented

2020-06-05T10:02:34+02:0028. June 2018|Our Products, News|

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.
