Cảm biến đo nhiệt độ Okazaki

OMC’s Range of Platinum Resistance Thermometers are approved by the Japanese Aerospace Exploration Agency (JAXA), as Qualified Parts for Aerospace Development.

OMC’s sensors are designed and manufactured to operate over the extreme temperature range of -260℃ to +930℃． These sensors offer excellent performance across this wide temperature range giving High Accuracy with fast Thermal Response, with no effect from High Vibration, Mechanical shock and adverse radiation levels.

These qualities have been proven by Okazaki’s sensors passing over 30 test conditions set by JAXA which are required before items are used in a live launch condition.

Okazaki sensors are also used on various aircraft and again have met the stringent criteria and conditions set by the Japanese Ministry of Defence. Okazaki’s sensors again offer outstanding performance with High accuracy and no effect from the adverse vibration conditions.

After extensive R&D and independent evaluation, we have developed a unique design of thermowell, the VortexWell®, which doesn’t require a velocity collar and is cost-effective for the end user in terms of purchase, installation and maintenance costs.

VortexWell® incorporates an innovative helical strake design, very similar to the helical strakes seen on columns and cooling towers. By using the latest CFD software to visualise the flow behaviour, we were able to accurately compare a standard tapered thermowell and its new VortexWell®. In the tests, the standard tapered thermowell showed classic shedding behaviour as expected, whereas the VortexWell® demonstrated no signs of regular flow behaviour. The VortexWell® helical strake design disturbed the flow sufficiently to interrupt the regular formation of vortices. Whilst a small vortex was observed in the wake of the VortexWell® this was a localised stagnation point and didn’t shed.
