摘要： A system and method for monitoring the operation condition of a wide variety of machinery is disclosed. A plurality of sensors, including temperature sensors and vibration sensors, are coupled to a controller. The controller receives input from the sensors and determines whether the temperature and vibration levels are within acceptable ranges with respect to baseline values. If the temperature and vibration levels fall outside the acceptable ranges, then respective visual indicators alert a user of such a condition. Multiple alarm levels are provided. A mounting arrangement is also provided in which a single threaded fastener can be used to attach the monitor to the machinery. The threaded fastener engages a through-wall metal recess in the monitor to efficiently conduct heat and vibration from the machinery to the temperature and vibration sensors within the monitor. The metal recess also serves to protect the monitor from damage during installation.

摘要： A system and method are disclosed for monitoring and controlling a positive displacement pump using readings obtained from a plurality of pressure sensors. The pressure sensors may be mounted at the suction, discharge and interstage regions of the pump. Signals from the pressure sensors are compared to obtain a ratio that is used to predict whether a cavitation condition exists within the pump. The ratio can be compared to user provided limits to change an operating characteristic of the pump to reduce predicted cavitation. The pump may be stopped, or pump speed changed, when the ratio is less than a predetermined value. In some embodiments, historical information regarding the ratio may be used to obtain standard deviation information which may then be used to predict whether gas bubbles are passing through the pump. Other embodiments are described and claimed.
