This powerful and low-priced solution enables measurement and monitoring of casing vibration, rolling-element bearing condition, Temperature simultaneously at 2 bearings of your machine. The acceleration sensor AS-062/T1 integrates a temperature sensor in the housing besides the elements necessary for vibration measurement. With the mounting of the sensor all three measured variables are acquired simultaneously and expensive addtional components and wiring costs are unnecessary.
Measurement of casing vibration is in accordance with the ISO Standard 10816. The two actual measured values are shown in the display, as well as their percentage values with respect to the set limit setpoint. A violation of the preset limit values is signalled visually (LED) as well as through the built-in relays for Alert and Danger alarms.
Rolling-element bearing condition monitoring
For acquiring the rolling-element bearing condition, a DFT of the sensor signal in the range 500 to 5000 cycles per second is performed, and the sum of the largest RMS value of vibration acceleration is formed. A comparison with the measured value of the measured value of the bearing (in as new condition), the 'Bearing Condition Value' is displayed.
provide you with an overview of the measurement trend, the VC-1500 has a trend measurement function for the casing vibration, rolling-element bearing condition and temperature. The display is provided right at the instrument over a selectable period between 10 days and 10 months.
The powerful and affordable solution for measuring and monitoring three parameters simultaneously at two bearings of a machine:
In addition to the elements required for vibration measurement, the acceleration sensor AS-062/T1 has a temperature sensor integrated into the same housing to enable simultaneous acquisition of all parameters, while eliminating additional installation and wiring costs.
Bearing vibration measurements are undertaken in accordance with the ISO standard 10816. The two current readings of the two sensors as well as their percentage value relative to the set limits are displayed on the monitoring device. If the pre-set vibration limits are exceeded, this is signalled both visually on the monitoring device as well as via the built-in relays for the pre-alarm and main alarm. An additional OK relay monitors the proper function of the device and the connected sensor. With this constant monitoring, any change to the condition of the machine is reliably recorded and reported. To allow additional monitoring devices to be connected, the system has two 4 … 20 mA analogue outputs proportional to the selected measuring range of the bearing vibration.
Bearing condition monitoring
To determine the bearing condition, the DFT of the sensor signal is calculated in the range 500 to 5000 Hz followed by the summation of the largest root mean square values of the vibration acceleration. The resultant bearing condition value is displayed following a comparison of the values derived from the as new condition of the bearing. Changes to this value indicate a deterioration of the bearing condition.
In order to obtain a historical overview of the measured values, VIBROCONTROL 1500 is equipped with trend measuring capabilities for bearing vibration, bearing condition as well as temperatures. The values are displayed directly on the device with a selectable period of 10 days to 10 months.
