The Bently Nevada 177230 Seismic Transmitter provides a 4-20 mA signal proportional to the 0-1 inch/sec 0-pk velocity movement of a roller element bearing housing or machinery housing. It is designed for use on non-critical machines. The transmitter automatically integrates the acceleration signal on the machine to vibration prior to sending the signal to the controller. The Seismic Transmitter also has a dynamic acceleration waveform output for advanced diagnostics that is accessible at the non-sensor end of the field wiring through either a patch panel or some other wiring technique.

The Bently Nevada 177230 Seismic Transmitter combines a reliable design with ease of installation and maintenance which to reduce training and service costs. When integrated into the PLC or controls system of an overall plant asset condition monitoring solution, the transducer will help users better manage downtime, optimize maintenance planning, and avoid unforeseen catastrophic failures of machinery assets.

Application Notes

Here's how some of our customers used this product.

Monitoring Bearings on a Cone Crusher

The Background: The customer, a mining company, is using a cone crusher to crush ore and needs to monitor the bearings for wear before they fail.

The Problem: When the bearings on the cone crusher wear out and fail, it results in metal-on-metal contact quickly resulting in expensive damage. The customer needed something to both trend the life of the bearings as well as shut down the crusher before damage to the crusher occurs.

The Solution: A GE Bently Nevada 177230 Seismic Transmitter was hooked up to the customer’s programmable logic controller via the analog output signal. They programmed a high vibration setpoint which will indicate when the bearing fails and immediately shut down the crusher before any damage occurs. The customer has standardized this set-up and plans to use it on all of their crushing equipment.
