Marshall Thermocouples
Marshall Thermocouples
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 a Type 'K' (NiCr/Ni) thermowire. These elements are simple to connect, very economical and easy to use with the lightweight lance and optional digital Fluke-pyrometer. 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 supplied with a certificate of conformity. All accessories, such as grips, lances and pyrometers are available from stock.
Types
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)
