Sink vs Source in relation to 4-20mA loop

When you talk about digital components, like proximity switches, a “source” component supplies power on its terminals and responds to the change in the load. A “sink” component, on the other hand, does not supply power to its terminals and responds to changes in the

Permanent Downhole Gauges: Analog vs. Digital

Downhole Piezo-Resistive Pressure Tools At GEO PSI we manufacture downhole instrumentation sensors which are sold in many different markets across the world. We sell both analog 4-20 mA downhole pressure tools and several types of digital tools. Both analog tools and digital tools utilize the same type of piezo-resistive transducer, which is often called a sapphire,

Downhole Instrumentation for Fracturing Operations

Communication between Frac wells is common in high well volume operating fields. The effects of this communication can vary from environmental leaks to equipment damage. Having the ability to monitor downhole pressures allows companies to observe pressure changes in nearby wells during frac operations of adjacent wells.  Monitoring pressure during the fracturing operation is vital

Using Real-Time Downhole Monitoring to Overcome Deferred or Lost Production

Downhole monitoring in SRP/PCP/ESP installations to help take pre-emptive measures to reduce downtime. The Issue Globally, the oil & gas industry routinely suffers an average of 5 to 7% of unplanned downtime due to unknown wellbore problems and poor maintenance practices. However, this number is skewed due to a majority of wells with smooth &
