Product Description
Overview
The PR6423/10R-040-HT paired with the CON021 signal conditioner is a high-temperature eddy current measurement system designed for continuous monitoring of rotor dynamics in extreme thermal environments. This assembly combines a rugged 8 mm proximity probe with a matched converter unit, delivering precise vibration and shaft displacement feedback in demanding rotating machinery applications. Its stable performance under severe heat makes it ideal for turbine sections and other high-temperature mechanical zones where conventional proximity systems lose calibration stability.

FAQ
Q: Can this probe be used on non-ferromagnetic shafts?
A: No, it is optimized for ferromagnetic steels such as 42CrMo4 or AISI 4140. Performance on non-ferromagnetic materials will not be accurate.
Q: What is the maximum temperature the probe can withstand?
A: The PR6423/10R-040-HT operates reliably up to 220°C continuous exposure.
Q: Are the output ranges configurable?
A: Yes, the CON021 converter supports dual output ranges: –4 V to 20 V or –2 V to 18 V.
Q: How does this system compare to lower-temperature eddy current probes?
A: Unlike standard probes, the PR6423/10R-040-HT maintains calibration stability and sensitivity in extreme heat, making it suitable for turbine and high-thermal zones.
