Omron Corporation has introduced four series of condition monitoring devices for workers to monitor the operational status at manufacturing sites:
• Motor condition monitoring devices that predict the failure of 3-phase induction motors.
• Power supplies that can predict service life and failures when installed in a control panel.
• Flow and pressure sensors that monitor hydraulic oil and cooling water for presses and moulding machines.
• Smart condition monitoring amplifier that accelerates IoT use of existing analog sensors installed in facilities or machines.
The release of the condition monitoring devices is part of Omron’s effort to complete a 100 000 IoT-components line up. The devices visualise facility and equipment condition constantly in order to detect status errors in advance, thus maintaining productivity.
The condition monitoring devices monitor changes in power systems and circulation equipment in real-time. They inform replacement time of parts before failures through communication networks and contribute to prevention of unexpected facility stoppages and quality abnormality of products. Personnel are alerted to signs of abnormality or impending failures, which enables them to reduce losses due to unexpected facility stoppages, and enhance the accuracy of maintenance plans.
Motor condition monitoring devices
Motor condition monitoring devices detect errors caused by age related deterioration of three-phase induction motors used for many applications on production facilities including conveyors, lifters and pumps. The monitoring devices detect errors by status changes in vibration, temperature, current and insulation resistance. Monitoring is by display on the main unit, or remotely via Ethernet/IP communications.
Power Supplies with network capability
Power Supplies with network capability visualise the information necessary to maintain and control the supply of power to equipment in production facilities. These power supplies can provide information on output voltage/current, and boost current by remote control using Ethernet/IP communications and the main unit monitor, contributing towards solving the following issues:
• Advance notification of the need for replacement.
• Monitor the total runtime voltage and current to facilitate maintenance requirements.
• Use in combination with the dedicated software Power Supply Monitoring Tool visualises power supply condition on the derating curve.
• Extended service life through measures to improve installation environments and changing power demands.
Flow and pressure sensors
A single sensor can now measure both the flowrate and temperature of cooling water used for a welding or moulding machine. This enables operators to detect and capture warning signs in order to achieve more stable welding quality, and prevent defective moulding.
The pressure sensors simultaneously visualise the pressure and temperature of hydraulic oil for machining centres and press machines. They capture signs of packing deterioration through temperature rise, thus allowing corrective action to be taken before hydraulic oil leakage results. They also use temperature to detect changes of the oil viscosity, thus maintaining stable processing quality. Through sensing multiple parameters such as flowrate, temperature and pressure, these sensors provide cost effective facility monitoring.
Smart condition monitoring amplifier
The smart condition monitoring amplifier connects to general analog output sensors. Omron offers the N-Smart next-generation sensor series that connect to fibre and laser sensors. Now, by means of the smart condition monitoring amplifier, users can connect to general analog output sensors, enabling them to build inexpensive networks with various facility condition monitoring capabilities.
Previously, obtaining data of analog output sensors required system up with expensive data loggers and measurement equipment. The unit can synchronise up to 30 sensors for real-time data collection at the facility, thus enabling the capture of subtle changes in reliability, enabling optimum machine control according to facility status changes.
