Motor Monitoring Services

image-265-orig

MCM monitors the condition of equipment driven by an electric motor, effectively using the motor itself as a sophisticated transducer. It uses advanced NASA-developed technology to provide automated set-up and fault diagnosis with minimal user intervention. It is simpler to use and more cost effective than conventional systems. MCM is applicable to a very wide range of driven equipment, including pumps, fans, compressors, and conveyors, and is particularly valuable for equipment in inaccessible or hazardous environments.

Simple to install

Installing MCM is a simple matter of connecting it to the three supply phases of the motor using simple and inexpensive transducers and mounting it in any convenient panel. It is usually located at the motor control cabinet, requiring very short cable runs and avoiding the need to install equipment in remote or hazardous areas. When first switched on, MCM carries out an automatic self-learning process during which the normal operating condition of the equipment is established. Advanced analysis techniques ensure that this training takes account of variables like speed and load, and that existing faults do not result in training errors.

Continuous monitoring of your machinery

MCM constantly takes measurements and compares them with its reference condition, in order to assess the severity and type of any developing fault. It is able to recognise abnormalities in a wide range of operating states, and is even able to extend its self-learning process when it recognises that it has moved beyond its original learning limits. This allows MCM to achieve very sensitive detection of faults without false alarms.

Reliable, automated fault diagnosis

When MCM detects a fault, it presents the results of its sophisticated analysis to the user in a simple, compelling traffic light display. This provides local staff with an immediate indication that a problem is developing. Detailed diagnostic information is provided by means of its standard networking facilities, and covers a very wide range of mechanical and electrical problems including imbalance, misalignment, bearing damage, leakage, isolation, and many others. A relay output is also provided so that specific alarm conditions can be annunciated by visual or audible warnings, or communicated to a control system.
