Our patented Spring Loaded Exhaust Gas Sensors eliminate premature sensor failures
Standard exhaust gas sensors in 7F and 9F class turbines are at risk of premature failure due to vibrations caused by gas flow velocities, input vibrations and thermal expansion mismatch.
Conax Technologies’ exclusive Spring Loaded Exhaust Gas Sensors are specially designed to withstand these vibrations and avoid premature sensor failures.
Our patented sensors have a high temperature compression spring that’s inserted between two spacer tubes. The spring dampens the vibration and keeps the temperature sensor tip seated within the radiation shield. With this increased stability, the sensor tips won’t break. So turbines run longer without the risk of premature sensor failure.

Customized EGTs for FT8 aeroderivative ground-based turbines
Pratt & Whitney FT8/GG8 frame users are choosing Conax Technologies’ exhaust gas thermocouples (EGTs) over OEM sensors in their turbines. Conax Technologies’ superior design meets or exceeds OEM functionality and has proven to be highly reliable through field testing and validation.
Conax uses two dual circuit ungrounded thermocouple probes that are manufactured for balanced loop resistance among all four circuits. This is superior in design to the OEM version that utilizes four single thermocouple probes.
Plus, our solution uses a four-post hermetic connector that exceeds OEM specifications and is adaptable to the existing cable harness. For more details, click here.
Explosion-proof rated Ex/MBS Series miniature bearing sensors
The bearings of rotating equipment operate in arduous conditions, and the seals in typical sensors can break down over time, leading to oil leaking and wicking. This results in the potential for oil to ignite and catastrophic failure to occur at the junction box and surrounding area.
Conax Technologies’ Ex/MBS Series explosion-proof rated miniature bearing sensors are your NEVER-FAIL solution. Specially designed to excel in harsh environments where typical miniature bearing sensors fall short, these sensors utilize a proprietary redundant sealing process that eliminates the risk of oil leaking and wicking. Our Ex/MBS Series sensors have received the most stringent certifications, assuring they’re safe in explosive atmospheres. View a demo here.

EGTs for FT8/GG8 Aeroderivative Ground-Based Engines
FT8/G8 users are choosing Conax Technologies’ exhaust gas thermocouples (EGT) over OEM sensors in their aeroderivative ground-based turbines. The innovative design in the Conax EGTs has proven to be more accurate and last longer than the OEM sensors. The key enhancement of Conax Technologies’ design is the use of two (2) dual thermocouple probes rather than four (4) single thermocouple probes. Conax employs unique manufacturing techniques to create balanced loop resistance between all thermocouples. The result is a more robust and reliable design that offers the same two (2) circuit, four (4) point averaging temperature measurements as an OEM sensor with superior accuracy and reliability. Here’s what sets the Conax EGTs apart:
- Superior design and quality
- Proven higher reliability than OEM sensors
- Hermetically sealed for high accuracy and long life
- Simple, quick installation that saves time
- Interchangeable with OEM sensors
- Typically in stock to provide quick turn around time

Bearing Sensors and Seals
The bearings of industrial rotating equipment operate under arduous conditions—often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the shoe. Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film, allowing machine shutdown and maintenance to take place before catastrophic failure of the bearing and possible damage to its mounting. Conax Miniature Bearing Sensors provide a simple and cost-effective method to monitor bearing temperatures. These sensors are for embedded applications where temperature monitoring is critical to machine performance and reliability. The unique bearing sensor wire seal prevents migration of oil along the sensor leads. Available with RTDs or thermocouple types J, K, T and E. Download Miniature Bearing Temperature Sensors
