The Artesis intelligent predictive maintenance system is simple and inexpensive to install. Monitors are connected to machinery using current and sometimes voltage sensors, and to plant networks using a range of communications devices.
At the customer’s option, Artesis can integrate the complete system including these accessories, or simply supply the necessary components.
For monitors connected to fixed speed machinery, simple current transformers are used for current measurements.
For monitors connected to variable speed machinery, Hall-effect current transducers are used for current measurements.
For monitors connected to high voltage equipment (above 450V), voltage transformers are also required for voltage measurements.
For many installations, simple serial communications based on the RS485 standard are a cost-effective way of providing plant-wide coverage. In such systems, monitors are networked using twisted-pair cables, and are then connected to a computer using an RS485 to RS232 converter unit.
Many plants now have site-wide Ethernet networking, and in such cases it is cost-effective to use this system to connect Artesis monitors. Typically, each local group of monitors is connected together using RS485 cabling which terminates in an Ethernet converter unit. This allows any computer on the network to control and monitor the entire system.
For remote sites, each local group of monitors is connected together using RS485 cabling which terminates in a GPRS modem unit. This then allows simple wireless communication with a computer using the GSM packet-switched network.
