Oil & Gas Wellhead with 31EP and 32EP Explosion Proof Pressure Sensors

Oil & Gas wellheads can be seen as you drive through the countryside dotting the landscape.   The wellhead is the interface between the oil and gas (that is below the surface and under pressure) and the structural connections above the surface to harness the fluid.  Each gas wellhead can produce enough energy to power 200 homes for one year.    

 

Handling and monitoring the gas requires that all systems in place have Hazardous Location (HAZLOC) certifications.  Each installation is different depending on factors such as the percentage of risk, how far away is the risk, what is the fluid/gas, etc.  

Many wellhead installations require an Explosion Proof pressure sensor.  An explosion proof pressure sensor differs from an industrial pressure by being able to contain the flame or the explosion in case an accident was to occur

 

Challenge:  Finding a pressure sensor vendor that supports various Hazardous Location applications, varying installation locations and has Explosion Proof Pressure options 

 

Not every pressure manufacturer has options for HAZLOC areas.  Many suppliers just focus on the standard industrial or laboratory style sensors.  Manufacturing a HAZLOC certified product requires that a company understands the requirements to fulfill the needs of the as well as adhere to the strict guidelines set forth by the certifying body. 

 

Also, HAZLOC rated explosion proof sensors can be installed anywhere in the world from the heat of Texas and the Middle East to the cold of Alaska, Canada, and Greenland.    A robust solution will need to not only survive these wide temperature fluctuations but also perform above the specifications.

 

Solution:  The Gems 31EP/31EP Explosion Proof Hazardous Location Pressure Sensors 

 

Gems manufacturers a wide variety of Pressure Sensors used in HAZLOC applications like those in the Oil & Gas markets.    Some are medium risk and are rated for Intrinsically Safe HAZLOC applications, some are lower risk and are rated for Non-Incendive HAZLOC applications. 

 

For the higher-level applications requiring a pressure sensor 
that is Explosion Proof rated, the CSA Approved 31EP/32EP 
are available.  The 31EP/32EP sensors utilize 
a ½” conduit electrical connection to safely connect the  
wiring to their wiring system. 

 

The 31EP/32EP Explosion Proof Sensors also feature a very wide temperature operating range of -40C to +95C.  This allows the sensors to operate safely and accurately in very cold and very hot temperature climates.
