Aavad Instrument melt bolt thermocouple are used to measure plastic melt temperatures as the material moves down the barrels in extruders and injection molding equipment. The element and bolt are both constructed from 304 stainless steel. The element is a MgO type with a grounded junction. The extension and tip lengths can be specified for your application. Melt bolts can be ordered with 1/2″-20 N. F. thread lengths of 3″, 4″, 6″, and 9″. Melt bolts can be made in many configurations, which are not shown in this catalog, contact one of our sales engineers and we can help you with your application requirements.
Note: if you would like to order a Type E, J, N, or Type T assembly, just substitute the K with an E, J, N, or T on this page. (Type J, Melt Bolt thermocouple, 3″ long bolt, 5″ extension, a male plug, 1″ tip)
Standard Features:
- Grounded Junction
- 1/2″ – 20 N. F. thread.
- 3O4 stainless steel heavy duty bolt.
- 3/16″ diameter 304 Stainless Steel tip.
- MgO construction for high-temperature resistance.
- Solid pin male plug.
MgO Melt Bolt thermocouple application:
Melt bolt thermocouple are machined from solid 304 stainless steel bar stock for corrosion resistance. The elements are constructed with MgO insulation for maximum temperature resistance. The tips are 3/16″ in diameter and also made from 304 stainless steel. A grounded junction is standard for a rapid temperature response time. All melt bolts have a 1/2″ – 20 N. F. thread for ease of installation. The extension portion of the thermocouple can be bent to suite your application.
