Datasheet

Bently Nevada Machinery Condition Monitoring

Description

The 177230 Seismic Transmitter is a simple, loop-powered
device that can be quickly and easily installed. It can be
integrated into your programmable logic controller (PLC)or
controls system linked to a plant asset condition monitoring
solution. Its simple design reduces training, maintenance,
and service costs. The transducer helps you better manage
downtime, optimize maintenance planning, and avoid
unforeseen catastrophic failures of machinery assets.

The 177230 Seismic Transmitter incorporates robust CM
design for reliability and implements an industry-standard 4
to 20 mA loop-powered transmitter.

Easily Installed and Integrated

l Interfaces with PLCs and control systems (including

DCS and SCADA)

l Requires only a short learning curve for operations and

maintenance –through a familiar interface similar to

that for connecting other PLC or control system inputs
l Requires no field configuration or adjustments
l Needs few additional parts for a complete system
l Includes technical support for customers on how to

monitor their equipment
l Includes self-test
l Incorporates protected interface
l Supports a variety of interface cables

This part typically mounts directly to
the machine via a stud. Customers
can use this device with a magnetic
base, but must take care not to “snap”
the unit onto the machine. This
snapping action can create a very
large spike signal that can damage
the electronics. Rolling the magnetic­base onto the machine greatly
reduces the spike signal so that the
unit should not have any issues.
