Plastic lndustry Therrnocoup'l€s - Melt Bolts

l:r,, jlr.

Melt bolt thermocouples 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 applications requirements. ? N96: tf you would tike to order a Type E, J, N, or Type T assembly, just substitute the K with an E, J, N, or T in the part numbers Iisted on this page. Example: MBTJ-3-5-J1-1 (Type J, Melt Bolt thermocouple, 3" long bolt, 5" extension, a male plug, 1" tip)

Standard Features:

,/ 3116" diameter 304 Stainless Steel tip. ./ MgO construction for high temperature resistance. ,/ Solid pin male plug.

,/ Grounded Junction. ,/ il2" - 20 N. F. thread. ,/ gO4 stainless steel heavy duty bolt.

MgO Melt Bolt ThermocouPle.

lVelt bolt thermocouples are machined from solid 3A4 stainless steel bar stock for corrosion resistance. The elements are constructed with MgO i nsulation for maxi mum 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 112" - 20 N. F. thread for ease of installation. The extension portion of the thermocouple can be bent to suite your application.
