DaqPRO Solution - Monitoring Temperature and Pressure at a Power Plant Facility


The impact on the power sector from the convergent forces of changes in customer behavior towards renewable and distributed energy and regulation is constantly creating new opportunities and challenges. Risk analysis is vital to ensure that the process is ecologically sound and environmental damage to surrounding areas is minimized.

Application: Power Generating Facility  

Organization: Energy Production, Transportation and Distribution.

Background:


The impact on the power sector from the convergent forces of changes in customer behavior towards renewable and distributed energy and regulation is constantly creating new opportunities and challenges. Risk analysis is vital to ensure that the process is ecologically sound and environmental damage to surrounding areas is minimized.  

 

About the Customer:

 

The customer transforms energy from AC to DC at several power stations and transfers it via a network of power lines which transmit the energy to various locations from each specific plant.

During this process extreme heat is created by the resistance caused during the transformation of this energy. In order for projects to remain ecologically sound, accurate monitoring and risk analysis are required throughout the transformation process. 

 

Key Customer Challenges:

  

Operators at the facility carry out periodic inspections and regularly log temperature and pressure during the energy transformation process which takes place, often at  90m below ground level. In order to measure the temperature of the heat and the pressure created during these underground processes, specific instrumentation is required. High-end battery powered hand held devices with external sensors and extremely long cables, able to measure temperature at great depth, providing each operator with the ability to read results onsite, in real time, and monitor underground developments as they occur often in vast open regions without the availability of regular power supplies or wifi.

 

DaqPro Implementation:

 

Numerous DaqPro units were placed sporadically at three separate energy transformation sites. Each unit was connected with seven separate external temperature sensors and one

transducer used via the 4-20mA input measuring pressure. The DaqPro units were kept above ground while the sensors were buried deep underground, with extra-long cables, to monitor during the transformation process. Each sensor was placed at a different point, mapped around the designated area, to ensure widespread readings, in real time, for each individual unit.

 

Measurable Results:

 

The DaqPRO logger was the perfect choice for the field monitoring environment of this project. Designed to operate without the need for PC connection, the DaqLab software for enhanced data analysis and device configuration was used on site, via the built in screen with graphical display. The data collected from the external sensors measuring temperature and the external transducers used via the 4-20mA input measuring pressure, was analysed, onsite, according to the sampling rate and the parameters previously programmed into the loggers.


The process is carried out come rain or shine therefore the weather box accessory, complying with the IP-67 standard will come in handy for protecting the DaqPRO while testing during the winter months. The rechargeable battery feature and carry case make packing away easy following testing and ensure the DaqPro will always be ready for the next round of next order testing.
