Utilizing Maintenance Sensors is an Extension of Preventive Maintenance, by John Kravontka...
Predictive Sensor Overview/Strategy
Utilizing maintenance sensors is an extension of preventive maintenance. It is based on the theory that equipment operates efficiently when measurements of temperature, vibration, sound, amperage, accuracy/alignment, pressure, etc., fall within acceptable limits. As the equipment wears, these measurements drift beyond those established limits. A sensor or group of sensors are continually or periodically monitoring those measurements and communicating with Maintenance so that they can determine the best course of action to bring the equipment back to optimum conditions.
Using agreed upon measurements, equipment failure can be predicted so that steps can be taken to prevent production downtime and more costly emergency repair. Unlike many preventive maintenance routines, these sensors will measure the equipment, while it is running.
Using these sensors we can develop a strategy for potential implementation at your facility.
Wireless Vibration Amplitude
Excessive vibration is one of the more common ways to predict equipment failure. Vibration analysis is used primarily on rotating equipment such as motors and turbines to determine shaft misalignment and bearing wear. It can also be used to detect imbalances, looseness and resonance. Wireless Vibration Amplitude Sensors activate at a user-defined interval and measures g-force along X, Y and Z axes. This sensor is ideal for detecting changes in activity, motion, or vibration on structures and equipment.
Wireless Remote Temperature Sensors include a sealed NTC temperature probe and can measure temperatures between -40°C to +125°C (-40°F to +257°F). This sensor is ideal for monitoring temperatures of critical motors, gearboxes, hydraulic systems, in harsh environments, difficult to reach locations, and in liquids. Users can set the inspection rate and thresholds for notifications.
Wireless remote amperage sensors can monitor critical motors that are driving pumps, gearboxes, hydraulic systems, etc. to predict impending failures.
