Pressure-spring type temperature sensor with excellent anti-vibration performance,
Large measurement range
High mechanical strength and superb pressure resistance
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples possess the advantages
o
f flexibility,
high-pressure resistance, quick thermal
r
esponse times, and robust durability.
Similar to prefabricated
t
hermocouples, they function as temperature measurement sensors
a
nd are often used with display instruments, recording
i
nstruments, and electronic
regulators. Additionally, they
c
an be utilized as temperature sensing elements in
assembled
t
hermocouple setups. They can measure temperatures of liquids,
s
team,
gas mediums, and solid surfaces ranging from 0°C to 1300°C
i
n diverse production
processes.
