The DSP Compact Wireless Remote Monitor (WRM) system is an eightchannel unit used to analyze and control machinery condition caused by vibrations and other variables. It is a 24/7 controlling device that can communicate via the commonly used 802.11b/g industrial wireless network.
Each of its eight channels can measure: acceleration, velocity, displacement and envelope. It also has two AC channels and two channels dedicated to measure temperature or any input that conforms 4-20mA.
Data can be stored in the WRM memory or transmitted to the host machine analysis and follow-up software. This software includes an alarm system, which activates the digital alerts or relays, besides providing continuous warnings on the host PC screen.
Benfits
Quick implementation and start-up, which reduces installation costs.
Additional system to predictive monitoring of machine condition. 24/7 reliable and maintenance–free monitoring system. Easy relocation and re-installation of the whole set.
Easy Wi-Fi connection allows savings in network installations.
Unit suitable for moving and difficult access machinery.
Expandable system for condition monitoring coverage.
Uses existing, already installed Wi-Fi infrastructure.
Hardware and software adaptable to machinery and/or equipment production control system. Operation completely suitable for machines in motion. For example: mining trucks, train locomotives, subway cars, etc..
Overview
Easy software management of different variables such as mechanical vibration, pressure, RPM, temperature remote monitoring.
Each monitoring module has 4-8 accelerometer channels, plus the auxiliary inputs for additional process variables and RPM registration.
The system software can control up to 200 different WRMs, which allow to process more than 1,200 measurements simultaneously.
The WRMs have relay outputs that can be used to activate instant alerts or activate kill switches if the thresholds configured in the software are exceeded.
The point programmed measurements can be scalar or spectral; the variables are configurable individually in each point.
The monitoring system is administered by the DSP Machinery Control software Configuration and Supervision, which will beresponsible for defining the online monitoring system architecture and data follow-up.

It is ideal for:
Critical and semi-critical machinery in the plant.
Remote monitoring via Internet and remote failure analysis.
Temporary imbalance detection and machine condition in production processes.
Recurrent failure follow-up; suitable for troubleshooting problems.
Bearing failure, cavitation and lubricant film performance follow-up detection.
Machinery with poor maintenance due to difficult access.
Long-term registration periods without connection. Unite allows for
previously stored data dumping on command, . Such as machinery on the field that maintenance personnel reach sporadically, like weekly or monthly.
