Pyrometer Assembly

The Morgan Blue Lightning Thermocouple Sheaths offer superior protection, excellent service life, quick response and ease of use for aluminum and other non-ferrous melting and holding applications.

Morgan Blue Lightning Thermocouple Sheaths are available with either a BSP, NPT pipe or without a pipe as a straight ceramic sheath for higher temperature copper applications. The pipe versions are also available as a complete pyrometer assembly to help speed-up installation and reduce labour costs.

PYROMETER ASSEMBLY

The pyrometer assembly comes ready for the tough foundry environment and is inspected and tested prior to shipment. They are specifically designed to provide a quick and technician free change out of the existing pyrometer with no additional effort other than plugging in the new pyrometer and screwing on the sheath.

Assembled, Tested and Includes

• Blue Lightning Thermocouple Sheath
• Thermocouple (Type K)
• Horizontal pipe and fittings
• Junction head and connectors
• Stainless sheathed lead (2m)
• Male connector
• Female connector (for connection to furnace)

CHOOSING THE CORRECT LENGTH

Fixed Pyrometer - A pyrometer is normally recommended to be long enough to measure the temperature 2/3 from the top of the crucible.

Floating Pyrometer ATS50329 Blue Lightning Thermocouples are often chosen to measure 100mm (4) from the top of the melt.

OPTIONS

CARE AND USE

Ensure that the Blue Lightning Thermocouple Sheaths are completely screwed into the fitting and that the thermocouple is long enough to make contact with the bottom of the pyrometer sheath. TIP: Apply thread sealing compound to the threads to avoid oxidation and possible premature failure.

Gently preheat the sheath prior to immersion into the molten metal bath to minimize thermal shock and eliminate any trapped moisture.

FAILURE TO PREHEAT THE THERMOCOUPLE CAN CAUSE PREMATURE FAILURE AND POTENTIAL INJURY.

At the end of every shift, be sure to gently clean the sheath of any dross or other buildup to ensure accurate temperature readings and to increase the life of the sheath.
