IL 400 RPZ

Device for measuring and evaluation of vibrations in rolling bearings with outer diameter up to 400 mm.

The device is intended to measure the vibration level of rolling bearings with outer diameter up to 400 mm. Its universal character predestines it for production, measuring centres and laboratories.

IL 400 RPZ consists of the mechanical part, electronic control unit and a sensor. The mechanical part consists of the electric motor, spindle, measuring plugs, adjustable sensor holder, sensor body which serves also as a radial load, radial loading equipment and accessories.

The electronic unit consists of digital electronics which serves for sorting out three basic groups and nine subgroups. The three basic groups which are shown on the screen with big digits are also represented on the electronic panel as colour light signals. The electronic unit contains a loudspeaker box with a broad band loudspeaker which serves for accoustic monitoring of the measured signal in the whole frequency range from 50 to 10,000 Hz.

The main part if the sensor head consists of a Brüel&Kjaer sensor with a conceptionally new arrangement. The sensor head also includes amplifying electronics which also serves as a radial load. The accessories consist of an radial loading equipment with holdingdown discs and measuring plugs.

The device measures and evaluates the speed or acceleration of vibrations in rolling bearings in three frequency bands according to DIN ISO 15 242:

• first band, 1 NF: 50 - 300 Hz
• second band, 2 SF: 300 - 1800 Hz
• third band, 3 VF: 1800 - 10,000 Hz
• band TH: 50 - 10,000 Hz, NF + SF + VF bands with the possibility of swithing off one or two bands
• IL 100 band: 300 - 10,000 Hz, it depicts the vibration values in the band of the older device IL 100
