Your Trusted Power Resistor Provider Since 1925

Forged for the Field Resistors for Oil & Gas

Products used in the Oil and Gas industry are subjected to harsh conditions, including temperature extremes. Ohmite’s use of high-quality oil and gas resistors, materials and engineering design ensure product stability and long life in these harsh conditions. With over 90 years of experience in resistive technology, you can be sure Ohmite can deliver in the most extreme conditions.

(In the high-stakes world of Oil and Gas, where operational failure can be catasrophic, your components must be unfailing. Ohmite engineers high-reliability power resistors and current sense resistors that are forged to conquer the industry's most extreme conditions. From the searing heat and intense vibration of downhole drilling instrumentation to the corrosive environments of subsea control modules, our solutions deliver exceptional stability and extended operational life

Leveraging 100 years of expertise in resistive technology, our robust designs utilize superior materials to withstand relentless shock, pressure, and temperature extremes. We provide proven, test components for misson critical applications, including intrinsically safe circuits and pipeline monitoring systems. When you need to guarantee safety and pervent costly downtime in the harshest environments on Earth, trust Ohmite to deliver unwavering performance.)

Critical Applications in Oil & Gas

Deep within the earth, our high-temperature resistors provide stable power for sensitive electronics in downhole drilling and logging tools (MWD/LWD), enabling accurate data collection under intense vibration and heat.

On the surface, our dynamic braking resistors are essential for the large motor drives (VFDs) on rigs and platforms, allowing for the safe control of heavy machinery like drawworks and pumps. For transportation, our precision current sense resistors are vital for pipeline monitoring, ensuring the integrity of corrosion-prevention systems and the efficiency of compressor stations. From wellhead to pipeline, Ohmite resistors provide the unwavering reliability needed to control energy, protect assets, and drive performance. 

Your reputation is built on reliability. Ours is too. Partner with an Ohmite engineer today, and let's build operational certainty into your most mission-critical application.
