Catalog excerpts

Model A2 Heavy Industrial Test stands, compressor control, hydraulic systems, process automation, pump and pneumatic systems control ■ Pressure ranges from 5 psi through • Six output signals to choose from • Optional absolute pressure ranges • Optional external zero and span The Ashcroft® A2 pressure transmitter is ideal for a broad spectrum of pressure sensing requirements found in heavy industrial, and test and measurement applications. It offers the instrument speci- fier a wide choice of construction and per- formance variables. The Ashcroft® A2 is designed and manu- factured to provide the user with accurate, reliable, and stable output data. This is board microprocessor, that is programmed during a unique digital compensation process, to provide extremely linear and precise performance over the entire speci- fied pressure and temperature range . 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.) Vibration Effect: Position Effect: ± 0.02% Typical CE Mark (standard): EN 61326:1997 + A1 :1998 Annex A Heavy Industrial Immunity (Annex A, Table A.1) Light Industrial/Residential Emission (Table 4) Overpressure (F.S.)*: Proof Burst 'For higher overpressure ratings use XK8 option See page 2 for additional option. ELECTRICAL SPECIFICATIONS Output Signal: Supply Voltage: (unregulated) Minimum Maximum Power Requirements: Supply Current: <5mA for voltage outputs Electrical Terminations: See To Order section (reverse) Circuit Protection: Reverse polarity and mis-wire proected Insulation Reslsance (Circuit to Case): 100Mohm @ 30Vdc PHYSICAL SPECIFICATIONS Wetted Materials: 316L SS diaphragm and presure port, optional 17-4PH SS diaphragm and 316L SS pressure port Ingress Protection Rating: Enclosure Code Refer to Ashcroft Model A2X for Explosion / Flame Proof configurations and Ashcroft Model A4 for Intrinsically Safe/Non-lncendive applications.
