Monitran General Purpose Monitoring Sensors are for use with PLC’s and other industrial controllers to provide the user with a continuous output of vibration usually as a 4-20mA signal. Changes in the monitor signal will allow the user to spot vibration changes in the part of the machine to which the sensor is attached. Rapid changes accompany such conditions as machinery working loose from its mountings, fan blade malfunction, bearing failure all of which require immediate attention and machine shutdown to avoid widespread damage and loss of machine time. If the signal is logged at regular intervals, gradually increasing vibration indicates wear in the part of the machine where the sensor is fitted calling for replacement or detailed study with a portable vibration analyser.
This type of information is required in a wide range of environments so while the basic output is common to all sensors in this category there are many variations allowing them to be used in those different environments ranging from:
standard industrial conditions
submersible and long term wet operation
approved under ATEX, IECEx and ANZEx for use in hazardous areas
