Single or Multi-Point Suspended Measurement Systems for Corrosive and Non-Corrosive Chambers and Wellbores.
Intrinsically Safe Gauges
We manufacture Intrinsically Safe pressure and temperature monitoring systems that are designed to attach to Stainless Steel and Incoloy cable. These systems can be inserted into wellbores, chambers, tanks, and vessels to accurately measure pressure and temperature and specified depth in hazardous environments. Fluid level and gradient density can also be measured.
Below is a look at how our systems operate in two of our most common applications, tank storage and wellbores.
Tank Storage

Especially in multi-gauge applications as shown above, our systems can be used to develop gradient density plots and liquid level calculations.

Applications with Explosion Potential
Whether it be monitoring propane tank storage, or optimizing an oil & gas well, there are many applications where hazardous materials or hazardous environments require highly reliable pressure and temperature monitoring.
Safety is our top priority at GEO PSI, and we are proud to build products that are designed to operate reliably and safely in some of the most demanding environments.
While our gauges can be deployed almost anywhere, below are some of the most common hazardous explosive environments where our systems provide critical data.
- Natural Gas Storage
- Propane Storage
- Industrial Processes
- Chemical Processes
- Industrial Applications
- Underground Coal Mine Dewatering
- Etc…
About Intrinsic Safety
Intrinsic Safety is a widely adopted protection concept in which the electrical energy within the equipment is restricted to a level which is below what may cause ignition, and limits the heating of the surface of the equipment.
GEO PSI GEOTRU gauges are Ex ia IIA T4…T1 Ga certified by IECEx
Ex – describes explosion protection.
ia – denotes that GEOTRU gauges are designed to be safe with 2 faults and suitable in Zone 0 area. Wellbore, Wellhead etc.
IIA – denotes protection in environments with Methane, Propane, Methanol etc.
T1 – means that GEOTRU gauges temperature protection classification is up to 450°C / 842°F
Ga – is the maximum equipment protection level, meaning that GEOTRU gauges are suitable for Zone 0,1, or 2.

Our intrinsically safe GEO4-20 105 IECEx certified 4-20mA pressure gauge is the first cost-effective solution designed for measuring real-time pump intake pressure for artificial lift systems in oil & gas wells. This gauge is able to withstand vibrational forces exerted by high horsepower progressive cavity, rod, and ESP pumps.
Our innovative intrinsically safe GEOTRU gauges are designed to provide quality downhole pressure and temperature data for high-temperature wells. Reliability is increased through the use of quality materials and construction, as well as the removal of PCB’s from the gauge itself.
