Some demand devices that are compatible with a unique chemistry, others require pressure instrumentation that won’t pose a risk to workers or processes and many call for instruments that can handle a wide temperature range. However, throughout the chemical process industries (CPI), there are a few items on everyone’s pressure measurement wish list. It seems all processors want to improve the overall efficiency of the process, all desire devices that are better able to record and communicate information, and all need more stability from their instruments. Fortunately, instrumentation providers are... http://www.che.com/software_automation_and_control/instrumentation_automation_and_control/pressure_measurement_and_control/9902.html Thu, 1 Nov 2012 0:00:00 EDT The DG25 digital pressure gauge provides a five-digit LCD readout in ranges up to 25,000 psi.
