Intelligent low cost vibration monitoring – for ARMS, VRMS, Peak and Unbalance for monitoring simple machines

Condition monitoring is an important factor in many different industries. There is continual pressure to reduce production and maintenance costs, but at the same time uptime, increase Overall Equipment Effectiveness. The conditions unbalance and overall vibration monitoring of plant machines, such as motors, fans and pumps, which are often monitored manually or not at all, ifm efector now has a simple and interesting alternative.

The recently developed unit from ifm efector, VNB211 monitors online the overall vibration condition of machines and plants according to ISO 10816.

This new unit is full of surprises as with the addition of a simple dual cable it is possible to add a further accelerometer – so now it becomes a dual point monitoring system.

Alternatively, if the second accelerometer is not required it is also possible to connect temperature or pressure transmitters to monitor and measure machine health.

The sensor has an integrated time-stamped history function for both process values for up to 800,000 values this equates to a reading every five minutes for three years. It is even possible to reduce the sampling time down to 1 sec intervals for a fast acting machine. A simple and reliable trending is therefore possible directly from the machine.

The sensor measures RMS in Velocity in mm/s or in/s which is quite common but also Acceleration in RMS is freely available.

The measured value and switch point status are indicated in the LED display and critical conditions can be signalled using two switching outputs or one switching output and one analogue output. Alternatively, it is possible to provide the sensor with a voltage supply using an optional USB-interface. The push-button programming makes the unit simple and fast to set-up but it is even easier if configuration software is utilised. If the VES004 diagnostic software which is available at no charge after registering on our website a whole new dimension is opened where full spectra and even Time waveform data and of course History is available.

ifm efector’s new vibration sensor is intelligent and simple to use and will compliment any machine that it is used on.
