PIDTutor publishes book on cascade control
Mastering Cascade Control book
PIDTutor has released a book entitled 'Mastering Cascade Control', which is designed to help technicians and engineers to implement and troubleshoot split-range control applications.
Cascade control uses two controllers with a single control valve to provide faster, more accurate control response to upsets.
It can be used for several different applications, such as heat exchangers, tank levels and distillation column control.
It is widely used in process industries such as pulp and paper, oil and petrochemicals and mining.
'This is a practical book for plant technicians and engineers, using straightforward rules and guidelines, without the complex math,' said George Buckbee, president of PIDTutor and author of the book.
'Mastering Cascade Control' covers all aspects of cascade control use.
Starting with the basics, the book discusses when to use cascade and when to avoid it; costs and benefits of cascade; how to configure the control strategy; how to commission the system, tune the loops; and how to train operators and troubleshoot problems.
At the EMC UK exhibition in Newbury on 8–9 October 2013, Teseq will showcase its local calibration and repair services alongside its range of EMC test instrumentation and amplifiers.
Teseq has expanded its capability in field probe calibration to deliver calibration data at all frequencies defined in the IEC 61000-4-3 standard. It can now offer field probe calibration data to 6GHz.
The decision to purchase a calibration service is often based on price alone. This price-only approach to purchasing can be a Trojan horse, hiding unexpected costs and a multitude of problems. This application note from Fluke presents information to help users to evaluate their calibration service providers’ calibration offerings and to see why the lowest-cost calibration may not offer the best value.
Seaward has introduced Calibrationhouse — a calibration service for electrical and electronic test and measurement equipment.
Arc Energy Resources has enhanced the weld overlay cladding and fabrication services it offers customers by investing in a Faro portable co-ordinate measuring arm (CMM) for its inspection facilities.
