General Purpose Thermocouples
Melt Bolt Thermocouple (Type 4M)
These robust thermocouples have been designed to withstand the high pressures found within the nozzles of plastics extruders and injection moulding machines where they are used in order to measure the temperature of the molten medium. Available as standard in either 76mm or 152mm bolt lengths with either a 5mm long or flush sensing tip length. Available in thermocouple types K, T, J, N and they have an insulated junction and are terminated in a standard round pin thermocouple plug. Suitable for use up to 600ºC (at tip) with a bolt thread size of 1/2 inch UNF20, 316 stainless steel.
