31EP/EA and 32EP/EA Series
Explosion Proof
	 CSA Approved
	 ATEX Approved
Oil & Gas equipment needs a pressure transducer that is reliable and able to withstand
extreme environmental and pressure conditions. Gems Sensors explosion proof units
offer an alternative to high priced, unreliable alternatives. The 31EP and 32EP are
CSA approved explosion proof, and the 31EA/32EA carries the ATEX approval. They
all feature all stainless steel wetted parts, a broad selection of pressure connections
and a wide choice of electrical outputs-the 32 Series of each group provide higher
proof pressures. Our manufacturing process includes the latest automated equipment,
producing consistent sensor performance.
The compact yet rugged construction of these units makes them ideal for installation
where space in a hazardous environment is at a premium.
