Engine Compressor Thermocouples Provide the Reliability Needed for Offshore Use

Offshore oil and gas platforms require an uninterrupted source of electricity to power a wide variety of specialized equipment used to drill for oil. Pumps, valve operators, critical communications, turntables, motors, and safety systems are just a subset of the drilling and production ecosystem requiring a reliable source of power. Just as critical is the large amounts of electrical power required for the habitation. Electrical generators provide the power for comfort heating, cooling, desalination of water, food preparation, and even waste processing. The power requirements of an offshore platform is not unlike that of a small town.

The most common source of power for these offshore rigs are diesel powered generators. While diesel is still the most common, alternative fuels such as gas, heavy oil, and steam turbines are being produced for offshore platform use. Major turbine manufacturers continue to develop technologies that efficiently use one, or a combination, of these fuels. Additionally, increased savings and efficiencies are being realized through adopting waste heat recovery systems. These recovery systems assist by reusing and recycling energy from exhaust gases of turbines and generators.

Conditions on offshore platforms are harsh. Equipment and components must provide stable
operation and, by design, reduce the need for frequent maintenance and overhaul.  A specialized temperature sensor, referred to as an "engine compressor thermocouple" is used on platform generator turbines. These are specially designed, heavy-duty temperature sensors used for measuring the exhaust gases from engines, turbines and compressors. These sensors are time-tested and built to withstand the harsh mechanical and environmental conditions subjected by offshore, marine conditions.

Duro-Sense Remembers and Thanks Those Who Serve and Protect Our Country

Veterans Day is a day of observance and celebration for those who have served in the United States military. Veterans Day was originally called Armistice Day because of the November 11 Armistice that ended World War I. In 1954 it was officially changed to Veterans Day to include Veterans of all wars. This holiday honors those who took an oath to defend the United States and our Constitution, from all enemies, foreign and domestic. Through the observance of Veterans Day, we remind ourselves of our Veterans patriotism, love of country and willingness to serve and sacrifice for the common good. Duro-Sense thanks our Veterans, past and present, for serving our country and protecting our freedom.

Three Simple Questions for Choosing Thermocouples or RTDs

What's the best choice for your industrial temperature sensing requirement, a thermocouple or RTD? In industrial installations, both types of sensor can be specified with similar mounting accessories, dimensional specifications, and instrument interfaces. However, there are three criteria you need to consider before choosing between an RTD or thermocouple probe.

First, what is the temperature range you are trying to monitor?

Generally, if the temperature exceeds five hundred degrees Celsius (500 deg C), thermocouples are for you. RTD's are best between -200 and 500 °C, while thermocouples have a range of -180 to 2,320 °C. For anything above 500 Celsius, you should select the appropriate thermocouple calibration for the sensing range you're working in.

Second, what type of sensor accuracy do you need? 

RTDs are more accurate temperature sensors, offer highly repeatable readings, drift less over time, and are suitable for high precision requirements. Thermocouples are generally less accurate and are subject to drift. Typical thermocouple accuracy is 2 deg. C.

Third, how about the budget you're working under? 

Thermocouples can be up to three times less expensive than RTD probes, making thermocouples a good choice if high accuracy and repeatability are not critical. One caveat though. Make sure you consider any additional cost incurred with long runs of thermocouple extension wire. For installations requiring dozens or even hundreds of temperature sensors, the significant difference in basic sensor cost is an important consideration.

These three criteria are VERY basic, and intended just to point you in the right direction. There are many other differences between thermocouples and RTDs that need to be understood before application.  Consult a temperature sensor expert prior to installing or specifying a thermocouple or RTD wherever or whenever failure can cause harm.
