Model A2X Explosion/Flame Proof Pressure Transmitter APPLICATIONS: Oil field equipment, upstream oil and gas production, natural gas compression and transfer control, alternative energy projects FEATURES: • FM, cUL and ATEX listed • Choice of 0.25, 0.50 or 1.0% accuracy • Pressure ranges from 5 psi through 10,000 psi • CE mark • 316L SS wetted materials, 17-4 PH optional • 304 SS case • Six output signals to choose from • Optional absolute pressure ranges available LOOK FOR THESE MARKS ON OUR PRODUCTS The Ashcroft® A2X pressure transmitter is ideal for a broad spectrum of pressure sensing requirements requiring approvals for explosion/flame proof. The Ashcroft® A2X is designed and 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 programmed during a unique digital compensation process, to provide extremely linear and precise performance over the entire specified pressure and temperature range.
