Emerson Online Prediction, Protection and Process Monitor

Emerson’s AMS Asset Monitor is a field-mountable device to collect data from driven

and non-driven assets by using different types of sensors such as piezoelectric and

eddy current vibration sensors. The monitor analyzes the data to determine machine

health and provide alarms where appropriate, and based on the machine state.

The AMS Asset Monitor is designed to carry a combination of up to 12 CHARMs –

VI Piezo CHARMs, VI Tach CHARMs, VI Voltage CHARMs, and compatible DeltaV™

CHARMs – to connect input and output signals.

AMS Asset Monitor can be used as a standalone prediction device with basic protection

functions, or can be integrated into a network of multiple AMS Asset Monitors with

connections to complementary systems such as Emerson’s Plantweb™ Optics platform.

The installation of additional software on PC or laptop is not necessary. Web browsers

can be used to configure and control AMS Asset Monitor.

The input signals measured by sensors mounted on the equipment are connected

through sensor-specific CHARMs to the signal processing of the AMS Asset Monitor.

The preprocessed sensor signals are forwarded to the prediction unit for analysis based

on predefined rules with configurable parameters. The prediction results are output

based on selectable logics through output CHARMs or forwarded to other connected

systems through the Ethernet interface. The input sensor signals are also forwarded

to the unit for basic protection. The typical reaction time of the basic protection is

<1 second. Detected alarms are issued via output CHARMs.

Emerson’s AMS Asset Monitor manages pervasive sensing while providing edge

analytic results. It’s designed to mount at the asset, reducing cabling requirements

and other installation costs. For larger systems, multiple units can be daisy-chained

together to extend asset coverage.
