VIBROCONTROL 920

Product catalog summary
Overview: The VIBROCONTROL 920 is a device designed to prevent machine damage by monitoring vibrations in machinery. It identifies potential issues caused by unbalanced rotating parts, alignment errors, and damaged components, which can lead to increased mechanical vibrations.
Vibration Monitoring: The system measures bearing vibrations according to ISO standard 10816. It converts surface vibrations into electrical signals to determine the RMS value of vibration velocity. Continuous monitoring allows for the detection of both gradual and sudden changes in machine condition, triggering alarms or shutdowns if preset limits are exceeded.
Electronic Control Unit: Housed in a plastic casing, the control unit is designed for control cabinet installation. It can be mounted on a profile rail or a mounting plate and is configured interactively using software.
Vibration Sensor: The sensor, which can measure vibration velocity or acceleration, is attached to the machine housing. It converts vibrations into electrical signals and connects to the control unit via a cable that can be extended up to 300 meters.
Parameter Configuration: The control unit offers interactive configuration for parameters such as measuring range, frequency, limit values, and relay time delays. It features a display for measured values and limit violations, and supports both closed-circuit and open-circuit operations.
Specifications: The device supports one vibration channel and various sensor connections. It operates within a frequency range of 1/10 to 1000 Hz and measures vibration velocity with an accuracy of 5%. The system includes alert and danger alarms with adjustable relay delay times.
Outputs and Power Supply: The device provides analogue signal outputs and operates on either AC or DC power. It is designed to function within specific environmental conditions, with an operating temperature range of 0°C to +50°C.
Scope of Delivery: The package includes the electronic control unit, vibration sensors, terminal protective housing, and signal cables. Various sensor designs are available for different measurement directions and environmental conditions.

VIBROCONTROL 920 During opration, machines are subjected to a number of influences which change the condition of rotating parts, bearings, machine housing and foundations and may result in costly damage or secondary defects. The most common causes of damage are: Unbalanced rotating parts as a result of manufacturing errors, material defects and normal wear 镕 Unbalance due to deposits on the blades of exhaust fans, blowers and air separators Unbalance due to asymmetric load-ing of centrifuges and separators Օ Unbalance due to eccentric wind-ing of wire coils Alignment errors due to assembly...
