Analog transmitters easily send process measurements from different areas in a plant to a central PLC where process control decisions can be made based on transmitter feedback. Analog transmitters are great cost-saving alternatives to single-point controllers. In situations where multiple sensing locations are required, single point controllers costs can add up quickly.
An inaccurately sized or improperly specified filter can undermine an entire high-performance liquid filtration system. There are a dozen key parameters to assess to determine the proper specification.
Selecting the correct device is crucial to successfully handling solids. It must deal with discrete pieces that have physical size, electrical properties, frictional differences and surface characteristics that can change with the environment.
With the new high risk chemical facilities federal anti-terrorism regulations, its time for the chemical industry to ratchet up its cyber-security efforts. Theres a surge in interest in cyber-subjects such as security certification, defense-in-depth strategies, risk-based planning and improved policies and procedures.
Todays plants come ready equipped with their own team of doctors in the shape of the many diagnostic and monitoring systems incorporated into instrumentation and other process equipment. And, like any good doctor, todays plant diagnostics can look beyond the symptoms of poorly performing instruments and provide insights into the health of the process itself.
Dont head off in the wrong direction when replacing motors. The type of service and the orientation of the motor determine which bearings it should have. Using the wrong bearings can lead to significant problems.
Automating procedures within control systems can serve to make your operators more effective and more consistent. With studies showing more than 40% of all plant incidents stemming from some form of human error, it makes sense to give automation a larger role in day-to-day operations.
