Armored Thermocouple
Product Brief Introduction:
Armored thermocouples provide the benefits
o
f flexibility,
high-pressure resistance, quick thermal
r
esponse times, and durability.
Similar to fabricated
t
hermocouples, they measure temperature
a
nd are often used with display instruments, recording
i
nstruments, and electronic
regulators. Additionally, they
c
an serve as temperature sensing elements for the
assembled
t
hermocouples. They can measure the temperatures of liquids,
s
team,
gaseous mediums, and solid surfaces within a range of 0°C to 1300°C
i
n various production
processes.
