Home Products PROGNOST®-NT


Automated machinery diagnostic system incorporating machine protection and online condition monitoring.

PROGNOST®-NT is the perfect solution for critical and uncritical Rotating Equipment. Machine operators who need to extend their MTBM (Meantime between Maintenance) by early failure detection rely on at least some of the PROGNOST®-NT software modules. The PROGNOST®-NT software modules can be 100% customized depending on the customers monitoring strategy or depending on the failure history of the machine of interest. The analyses results of the different sensor signal-analyses combinations are accessible by the Visualization software “VISU”. The easy-to-use VISU gives full transparency regarding what happened inside the machine. Applied by the customer himself and/or PROGNOST Customer Support, it allows to get quick information but also an in-depth view to the analyses results.

Sensor signal acquisition and SIL 3 certified Machine Protection of all Rotating Equipment

The machine protection is based on vibration and critical parameters such as dynamic rod/shaft position and dynamic pressure.

Signal plausibility checks to avoid false alarms and warnings

Specialized signal processing avoids false warnings caused by broken wires, loose sensors, and other electrical failures.

Automatic 10-minute ring buffer for detailed root cause analyses (RCA)

Continuously recorded uncompressed signal data of all connected sensors (hardwired and DCS connected) are available for detailed root cause analyses. This ring buffer is automatically saved in case of an alarm, at every start/stop, or when user initiated.

Early Failure Detection

PROGNOST®-NT automatically recognizes changing machine operating conditions and adjusts the monitoring thresholds to avoid false warnings caused by variables such as changing load conditions.

Reliable and meaningful piston rod position for reciprocating compressors

Conventional monitoring methods use rod drop measurements for wear monitoring purposes only. PROGNOST®-NT uses the dynamic piston rod position for reliable rider ring wear calculation and to monitor the mechanical condition of piston rod, piston and crosshead connections.

Automated p-V diagram analyses

PROGNOST®-NT processes the online p-V diagram with dedicated analyses to optimize machinery performance and to detect leak sources, such as suction/discharge valves, packing, or piston rings. Further, it calculates dynamic piston rod loads to provide an early
warning of overload.

Pattern recognition with fully integrated diagnostic database

Each PROGNOST®-NT system automatically generates and saves new damage patterns when component failures occur. All major failures are analyzed and integrated as failure patterns into the systems’ diagnostic database, along with more than 150 patterns derived
from millions of operating hours.


Machinery health to go

The PROGNOST®-NT Web App allows you to keep track of your rotating equipment and machinery health status. You receive comprehensive information and key health indicators to help you make effective maintenance decisions.
The App is HTML-based and runs on all mobile device operating systems. It is an integral part of the PROGNOST®-NT version 19 upgrade and can be activated with your existing software license.


  • Essential machinery health information available on mobile devices
  • Includes diagnostic messages and alarm status
  • HTML-based application; can be displayed on PC, Tablet or Smartphone (all devices that run a web browser)
