We want to extend the temperature range of a sensor (consisting of ceramic, platinum and platinum/rhodium components) from 1000°C up to 1600°C. In the current design the platinum wires that hold the sensor parts in place become to soft and lose their stability causing the sensor to deform. The design needs to be changed to improve the stability of the sensor. The sensor needs to maintain its ‘thermal balance’ and heat transfer to the balance (that holds this sensor) should not increase.

Extending the lifetime of the sensor would require less replacement sensors and consequently the use of the rare metals used in the sensor.
It would also improve the performance of the instrument and make the use of an autosampler easier.

The most ideal result would be a sensor that meets the given requirements. A realistic expectation would be some suggetions how to improve the current sensor design or suggestions for a different design.
