Prefabricated Thermocouple
Product Brief Introduction:
Industrial prefabricated thermocouples serve as essential sensors for measuringtemperature, typically used in conjunction with display, recordinginstruments, and electric regulators. These thermocouples can directly measure the temperature of liquids, steam, gas media, and solid surfaces within the range of 0°C-2300°C in various industrial processes.
Features:
Simple assembly,easy replacement
Pressure spring type temperature sensor with excellent anti-vibration performance,
Large measuring range
High mechanical strength and good pressure resistance
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples offer the benefits
o
f flexibility,
high-pressure resistance, quick thermal
r
esponse, and remarkable durability.
Similar to prefabricated
t
hermocouples, these sensors accurately measure temperature
a
nd are often paired with display instruments, recording
i
nstruments, and electronic
regulators. Additionally, they
c
an function as temperature sensing elements for
assembled
t
hermocouples. These devices can measure the temperature of liquids,
s
team,
gas media, and solid surfaces ranging from 0°C to 1300°C
i
n various production
processes.
Features:
Short thermal response time reduces dynamic errors
Flexible installation and usage
Large measuring range
High mechanical strength and good pressure resistance
Explosion-proof Thermocouples
Product Brief Introduction:
Typically used with display instruments,
