PhoenixTM supplied a hot-box temperature monitoring system to Nichidai Thailand, which is part of Nichidai Japan and a manufacturer of components for the automotive and aerospace industries. The system will be used in its batch and low-pressure carburizing furnaces, where furnace surveys are a requirement for CQI-9 and AMS 2750. The system is charged into the furnace as part of a normal load and uses two-way RF telemetry to monitor the survey externally. It is able to operate in both types of furnaces and, when required, can be fitted with a deflector shield to withstand the high-pressure gas quenches.
