Model A2X Explosion/Flame Proof Pressure

Brand: Ashcroft Inc.

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.
