Armored Thermocouple
Product Brief Introduction:
Armored thermocouples offer the benefits
o
f flexibility,
high-pressure resistance, and a rapid thermal
r
esponse time. They are sturdy and durable. Just like their fabricated counterparts,
these thermocouples act as pivotal sensors for temperature
m
easurement and are usually used with display instruments, recording
a
nd electronic regulators. Additionally, they can serve as the temperature sensing elements of assembled thermocouples. They measure the temperature of liquids,
i
nstruments and electronic
regulators, meanwhile, it
c
an used as temperature sensing element of the
assembled
t
hermocouple. It can measure the temperature of liquid
s
team,
gas medium and solid surface range to 0°c~1300°c
i
n various production
processes.
Features:
Short thermal response time to minimize dynamic tolerance,
flexible installation and usage,
Large measuring range,
High mechanical strength coupled with superb pressure resistance.
