ANSSEN Thermocouple, your first choice!
1. Introduction
fast thermocouple is a sensor for temperature measurement. It can be connected to a fast potentiometer or a digital instrument to measure temperatures of melted iron, steed or other metals. There are two tupes of thermocorples made in our plant.
Specification
Type | Calibration no. | Composing Materials | |
+leg(1) | -leg(2) | ||
K | S | PtRh10% | Pt |
K | B | PtRh30% | PtRh6% |
K | R | PtRh13% | Pt |
K | W | Tungsten-3%rhenium | Tungsten-25%rhenium |
Note(1):The +leg means a leg to be connected to +terminal of an instrument to measure thermal electromotive force and -leg means opposite side one.
