‘Esterline Advanced Sensors / Weston Aerospace’ is nowadays called ‘Auxitrol Weston’. Auxitrol Weston, based in Farnborough England, designs and manufactures temperature sensors, speed probes and pressure sensors for aviation and industrial applications. Auxitrol Weston is an approved supplier to Rolls Royce (Siemens) and General Electric for critical gas turbine sensors and probes.

Auxitrol Weston advanced sensors

Auxitrol Weston advanced sensors develops and manufactures temperature, speed and pressure sensors for aeroderivative industrial gas turbines.

Auxitrol Weston is an approved supplier to General Electric and Rolls Royce for high quality gas turbine sensors and probes. Auxitrol Weston advanced sensors are especially known for their calibrated Weston T4.8 thermocouples 1696M81P13. Due to their accuracy Auxitrol Weston thermocouples enable gas turbine operators to improve their power output as they permit the engine to be run closer to manufacturer specifications.

With their constantly evolving thermocouple and total air temperature sensor technologies, Auxitrol Weston advanced sensors is the global market leader for temperature sensors. Their high-precision temperature and pressure sensors offer an extreme high reliability. Auxitrol sensors measure temperature of gas, fluids and surfaces, at an operating temperature range of -256°C to +780°C. Recent tests have indicated that even after 20.000 hours of operation the drift on the temperature sensors was minimal.
