As electronic measurement, microprocessor or computerized control, and wireless networking have worked their way deeper into industrial processes, new opportunities for accuracy, convenience, and cost-saving efficiency have multiplied. Electronic accuracy and communication have delivered performance advantages down to even the simplest functions — including pressure readings.
Among the many types of pressure gauge designs — from Bourdon tube to diaphragm, to capacitance/inductance, to piezoelectric sensing technology — each comes with its own range of accuracy and advantages. Getting maximum value from an instrumentation purchase is not simply a matter of choosing the lowest price, but rather choosing the performance characteristics that best fit specific application needs. Here are some considerations for maximizing value and avoiding unpleasant surprises in water/wastewater treatment plant (WTP/WWTP) pressure measurement applications.
