Model A2X Explosion/Flame Proof Pressure Transmitter Oil field equipment, upstream oil and gas production, natural gas compression and transfer control, alternative energy • Pressure ranges from 5 psi through • Six output signals to choose from • Optional absolute pressure ranges The Ashcroft® A2X pressure transmitter is ideal for a broad spectrum of pressure sensing requirements requiring approvals manufactured to provide the user with accurate, reliable, and stable output data. This is accomplished through the use of an on board microprocessor, that is pro- grammed during a unique digital compen- sation process, to provide extremely lin- ear and precise performance over the entire specified pressure and temperature PERFORMANCE SPECIFICATIONS Accuracy, Three Classes (% Span): ± 25 ±0.5 ±1.0 ncludes non-linearity (Terminal Point Method), hysteresis non-repeatability, zero offset and span setting errors Best Fit Straight Line* (BFSL): ±.20 ±.40 ±.50 nclucles non-linearity hysteresis, non-repeatability errors < ±0.25% Span/year® reference conditions Durability: Greater than 10 million cycles ENVIRONMENTAL SPECIFICATIONS Temperature Limits: 'Consult factory for other options • 1.0% of Span for .25% Accuracy Class • 2.0% of Span for .50% and 1.0% Accuracy Classes Humidity Effects: No performance effects from 0 to 95% relative humidity, non-condensing 'Consult factory FUNCTIONAL SPECIFICATIONS Pressure Ranges: Vacuum, gauge, compound and absolute pressure from 0-5 psi through 0-10,000. Equivalent ranges In bar available. See order guide section (reverse.)
