Area classification drives instrument selection. Get it wrong and the whole installation falls foul of the inspector.

Flameproof equipment is commonly specified for gas hazardous zones in oil and gas plant. The Ajax XP ATEX pressure switch from F. Bamford is a flameproof design built for potentially explosive atmospheres. Always check the certificate and datasheet for equipment category, gas group and temperature class against your area classification drawing. The Bamford team can talk you through it.
