Instrotech, is promoting Monitran General Purpose Monitoring Sensors, for use with PLC’s and other industrial controllers. Monitran 1185C provides the users 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.
