Specifications: Fluke 721 Pressure Calibration Instruments. Absolute, gage, & true gage pressure sensors for test & measurement specs, from general industrial processes to specialized hazardous locations. High Stability/High Accuracy Pressure sensors Most pressure transducers feature an accuracy of 0.25% of full scale or higher. So, if a pressure transducer can measure between 500psi and 2500psi, then the span of the pressure transducer is 2000 psi (URL – LRL). A pressure transducer rated for 1000 psi with a resolution of 0.1% means that it will be able to measure pressure variations as low as 1psi. View: Filter by: Display. Dynisco traditionally recommends a well regulated 10 VDC power supply as excitation for most (unamplified) models of pressure transducers. Pressure transducer accuracy is the closeness of the measured value to the actual value. change from 70°F (21°C) = 80°F (44°C), 80°F X .004%/°F = .32% FS DZ/DT or 44°C X .0072%/°C = .32% FS DZ/DT, 80°F X .003%/°F = .24% FS DS/DT or 44°C X .0054%/°C = .24% FS DS/DT. The relationship of a calibration curve to a specified straight line. A piezoelectric sensor internal circuit is given above. Resolution is expressed in percentage of FSO (Full Scale Output). However, they are very different in terms of how a device works and how well it can report measurements. Results in a change in the slope of the curve. Average resolution is the median of the best and worst values. This relationship is always given in the manufacturer's product specifications. When we excite the transducer with pressure, the diaphragm will move accordingly. The Echo™ Series of melt pressure sensors offer quality performance and value for plastic processing utilizing standard configurations and pressure ranges. The cost of the pressure transducer varies directly with its response time where high-speed pressure transducers can cost significantly more than transducers with a low-frequency response. Hence, it is one factor that is never overlooked in the design and construction of pressure transducer. Read the specs here. Does not affect linearity or accuracy. For example, the operating temperature of the CS10 Industrial Pressure Transducer is listed as -40 to +85°C.

Description The pressure transducer design previously supplied by CPC, which were Eclipse transducers manufactured by Data Instruments, have been discontinued in favor of an improved transducer design. These MEMS-based pressure sensors provide robust solutions for the appliance, medical, consumer, industrial and automotive markets. Transmission may be via an analog signal such as 4-20ma or a digital signal such as Ethernet. Upon a loss of signal, the uCP-242 will eventually bleed the pressure in the branch line. The linearity of a pressure sensor is rarely indicated as a separate component. For the purposes of this article, such a signal is electrical. Most controllers amplify these tiny voltage signals from the transducer to properly read the data. This makes it hard to establish the measured valued as the most certain value. High Stability/High Accuracy Pressure Transducers Most pressure transducers feature an accuracy of 0.25% of full scale or higher.
