Description

The Bently Nevada Seismic Probe Velocity Sensor System is designed to measure absolute vibration (relative to free space) of a bearing housing, enclosure, or structure.

The two-wire system consists of a transducer and appropriate cable.

The Seismoprobe series of velocity sensors is a two-wire design using moving coil technology.

It provides a voltage output proportional to the vibration velocity of the sensor.

Moving coil sensors are less sensitive to shock or pulse excitation than solid state velocity sensors.

Solid-state velocity sensors are themselves accelerometers with embedded integrated electronics.

Moving coil sensors are less sensitive to shocks or pulsed www.abb-drive.com excitation and are a good choice for some applications.

Portable measurement applications are facilitated by the fact that no external power supply is required.

Available Types

There are two types of seismic probe velocity sensors:

l 9200: The 9200 is a two-wire sensor suitable for continuous monitoring or periodic measurements with test or diagnostic instruments.

When ordered with the optional integrated cable, the 9200 offers excellent corrosion resistance without the need for an additional cable.

l 74712: The Model 74712 transducer can be used for continuous monitoring or periodic measurements with test or diagnostic instruments.

l 74712: The 74712 is the high temperature version of the 9200.

Interconnecting cables can be used to connect 9200 and 74712 sensors to other instruments.

Other Instruments. These cables are available in various lengths, with or without stainless steel armour.

When ordering the 9200 and 74712 Seismic Probe Velocity Sensors, expect approximately six weeks lead time.

Approximate lead time is six weeks. Lead times vary depending on component availability and configuration.

For estimated lead times for specific orders, contact your local Bently Nevada representative.

SPECIFICATIONS

Unless otherwise noted, specifications are for machine enclosure vibration of 25 mm/s (1 in/s) at 100 Hz (6000 cpm) with a 10 kΩ load at approximately +22°C (+72°F).
