ACE ESP is the most reliable ESP sensor available in the world with a 99% of all units produced, still in operation. The extreme durability of these sensors render them virtually indestructible. Drop tested from 6400 ft (with a motor on top), the sensor continued to work and within specification. The ACE downhole unit is a completely sealed and welded device. ACE tools are routinely pulled from destroyed, contaminated, burnt motors and re-run immediately without requiring factory or shop service. Many ACE sensors have been deployed more than 20 times on replacement pumps and motors without any sensor service required.

ACE Reliance sensor features high reliability digital transducer, SS Duplex 2205 housing and is welded with the electron beam method. ACE Reliance has been proven highly reliable in harsh operating conditions of West Test Texas with very first sensors installed still up and running.
