Ashcroft A2X Explosion/Flame Proof Pressure Transmitter

The Ashcroft® A2X pressure transmitter is ideal for a broad spectrum of pressure sensing requirements where explosion/flame proof hazardous location ratings are required. 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.

Features

Choice of .25, .50 or 1.0% accuracy
Explosion proof and flame proof approvals, cUL and ATEX
Pressure ranges from 5 psi through 10,000 psi
CE mark is standard
316L SS wetted materials
304 SS case
Six output signals to choose from
Optional absolute pressure ranges available

Applications

Oil field equipment
Upstream oil and gas production
Natural gas compression and transfer control
Alternative energy projects
