Pressure Transmitters translate low-level electrical outputs from pressure sensing devices to higher-level signals that are suitable for transmission and processing. Pressure transmitters are capable of performing various pressure measurements and displaying amounts in different units. Pressure transmitters produce several types of electrical signals, including analog voltage and analog current.
Pressure Vessel Inspection involves a series of tests performed on pressure vessels to find critical weak points that potentially lead to dangerous and uncontrollable reactions. This inspection involves ensuring that the pressure vessel is free from ruptured seams or seals and cracks.
The procedure of pressure vessel recertification includes obtained design documentation & service records, performed stress, fatigue & fracture analyses to establish regions to be subjected to nondestructive examination, performed nondestructive examination of selected regions & features, performed repairs or analysis to demonstrate the permanent or temporary acceptability of defects, defined the conditions & lifetime for system recertification, and the cyclic interval at which the next inspection is necessary as well as established areas requiring repair & recommending repair and/or replacement based on cost effective analysis. This process costs approximately 15% of the cost of replacement, and the necessary downtime is minor, so there is a major economic incentive for recertification rather than replacement of systems and components.
