Ultra-high temperature sensors (UHT-12™) for research and monitoring
Vibration tests performed on the most demanding engines require accelerometers designed to be able to withstand very high temperature environments.
For example, industrial turbine engines, aircraft gas turbines, exhaust systems, rocket propulsion systems, automotive exhaust gas monitoring, catalytic converter testing, engine system testing and brake testing. Ultra-temperature sensors for research and monitoring.
These high-tech accelerometers are provided by PCB Piezotronics together with Grupo Alava, in order to provide the highest accuracy and the lowest noise during large temperature variations in the most stringent environments, thanks to the developed crystal, UHT-12™.
Our PCB sensors manufactured with this UHT-12™ technology have a higher data quality compared to those designed with ceramic crystal.
Among the technical advantages we can bring you:
- No pyroelectric noise peaks up to 1400 ºF (760 ºC)
- Constant sensitivity over a wide temperature change (as in conventional accelerometers the sensitivity varies with temperature)
- Shear mode crystals isolated from base strain and transverse measurement errors.
- The glass technology created comes sealed in an airtight package and has demonstrated reliable high performance in hundreds of gas turbine installations for research and monitoring.
High temperature dynamic pressure sensors:
A great advantage of these UHT-12™ sensors is that they operate without cooling up to +1200 °F (+650 °C) in turbines. It is recommended that hard line cables be used for operating temperatures above +500 °F (+260 °C). In addition, the cable can be soldered to the sensor for operation in pressurized environments. All these features will ensure highly reliable operation in high temperature environments.
What we would like to highlight about them:
- Hermetically sealed and laser welded housings.
- Fused ceramic insulation connectors.
- Internal acceleration compensation minimizes sensitivity to vibration.
- Calibration supplied at room temperature with thermal coefficients up to operating temperatures.
