Marshall Thermocouples and Accessories

The ready for use MARSHALL temperature sensor is a combination of a high temperature resistant steel tube, covered with a thin graphite coating and assembled with a thermo wire. The element can be used directly and without pre-heating.

A MARSHALL thermo-element consists of a chromium-steel tube type SS 446 / DIN 1.4749 and two type K (NiCr/Ni) thermo wires. These elements are simple to connect, very economical and easy to use with the lightweight lance and optional digital pyrometer.

Small tip at the hot end for quick response

The hot junction is welded into a small diameter tip. Because of the wall thickness of only 3 mm at this sensible point, very quick temperature readings can be made. The solid construction of the assembly guaranties a very good service life. Through this combination of quick response, long service life and low price MARSHALL became the very well reputed market-leader he is today, the best in his class and reported to be superior.

Standard type K class 1 elements according to European standard IEC-584. Upon request all elements can be furnished with a certificate of conformity.

All accessories, such as grips, lances and pyrometers are available from stock.

The advantages of Marshall elements are:

  • extremely low costs per temperature reading
  • can be used up to 1350 ºC
  • quick response time due to the thin wall at the hot tip
  • several hundred measurements in aluminium, excellent durability in bronze, brass and copper (-alloys)
  • easy to use and lightweight design
  • excellent resistance to chemical corrosion of molten aluminium and copper (alloys)
