Internal signal conditioning

The signals from the vibration sensor are amplified and conditioned by the accelerometer unit itself before being passed to the data acquisition system through a disturbed industrial medium. Our accelerometers are equipped either with a voltage output or a 4-20 mA current output.

The advantage of a voltage or current output also allows for the use of standard connections and acquisition modules (cables, terminals, process inputs etc.) therefore eliminating the need for special cables, fragile connectors or dedicated equipment.

These types of outputs, particularly the current loop output, offer an adequate level of immunity to electromagnetic interference even when a long connection cable is connected to the acquisition system.

Level of protection

The RECOVIB® accelerometers are sealed to an ingress protection level of IP67. We are able to design and develop custom-made units using special protective materials (for example, 316L stainless steel for marine environments).

Galvanic isolation

The RECOVIB® accelerometers offer galvanic isolation of the signal conductors. An additional isolation module is therefore not needed. Multiple sensors can be distributed in multiple locations and connected to the same acquisition system without signal degradation, even in environments with high ground potential differences due to heavy electrical loads operating in close proximity.

Wide frequency range with low frequency response

The RECOVIB® accelerometers operate down to DC allowing for the accurate measurement of low frequency signals. They are therefore also suitable for the monitoring of slow processes (such as monitoring the foundation movements of an off-shore wind turbine etc.).
