The melt-bolt thermocouples are used on extruders and injection molding machines to directly measure the melt temperature of plastic as it moves down the extruder barrel.
These melt-bolts are made with 300 series stainless steel and are constructed using a metal-sheathed MgO element.
The fixed tip style consists of an MgO element brazed to the bolt at a specified tip length and is supplied with a grounded junction as standard.
Pyromation's Precision Tip Re-adjustable MeltBolt Thermocouples come standard with a fast response exposed junction. The precision tip is manufactured from hardened stainless steel and creates a positive shut off to prevent the back flow of plastic into the bolt.
