Maintenance Mesure Controle (MMC) is established in 1989 in Thionville, France. Specializing in predictive maintenance for seventeen years, Maintenance Mesure Controle (MMC) is capable in assisting in installations control using acoustic leak detection, infrared thermography and vibratory analysis.
MMC offers customized valves and traps leakage testing services, database development and test procedures for industrial applications.
 Acoustic Leak Detection
The acoustic method principle is to identify leakages signals through ultra-sounds emitted nearby the valve shut-off WITHOUT ANY LOSS OF PRODUCTION.
To determine leak severity, MMC uses a digital analyzer with these technical specifications: 
-
Touch-sensitive screen
-
Acquisition card up to 2400 kHz
-
Acoustic emission sensor
-
All configurations available
-
Fanless
-
Intrinsically Safe. (Explosion proof)
Infrared Thermography
The infrared thermography principle is to remote establish a thermal cartography of an object by using the infrared radiation of this one.
 
The Infrared Camera
MMC uses an infrared camera with these technical specifications:
-
Sensor: uncooled microbolometer 320x240 px
-
Thermal sensitivity: 0.06°C to 30°C
-
Spectral range: 7.5 to 13µm
-
Temperature ranges: -40°C to -120°C and 0°C to 500°C
Applications to Predictive Maintenance:
-
Electrical: Electrical cupboards, connections testing, short-circuits...
-
Furnaces, boilers: Control of refractories, of heat insulators...
-
Mechanical: Control of bearings, of driving belts...
-
Valves & fittings, tanks: Leakages detection, pipes erosion detection, level and sediments control...
-
Building: Leakage of underground pipes...
Vibratory Analysis
Machinery Defects Detection with the Vibratory Analysis
The vibratory analysis in Predictive Maintenance allows to draw up a diagnosis of operation of your revolving machines during operation.
 Advantage of this method is to detect the defects as of their first appearance, to supervise their evolution and to correct them before the
appearance of damages. Condition monitoring makes it possible to plan the interventions of maintenance (human resources, spare parts, estimated budget) well upstream of breaks.
A good practice of Conditional Maintenance allows to reduce the costs of systematic and corrective maintenances by replacing the defective parts before damage.
Condition monitoring of the rotating machines allows to detect several types of defects, especially unbalances, misalignments, belts or bearings problems.
Advantages:
Improvement of your plants efficiency,
-
Lower valves maintenance costs,
-
Fewer forced outages,
-
Optimize predictive maintenance interventions for your plants.
