Prefabricated Thermocouple
Product Brief Introduction:
Industrial prefabricated thermocouples are essential sensors designed for measuring temperature. They are typically used in conjunction with display and recording instruments and electric regulators. These sensors can directly measure the temperature of liquids, steam, gas mediums, and solid surfaces within a range of 0°C to 2300°C for various industrial processes.
Features:
Simple assembly, easy replacement,
Pressure spring-type temperature sensor with excellent anti-vibration capabilities,
extensive measuring range
high mechanical strength, and superior pressure resistance.
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples offer distinct advantages
o
f flexibility,
high-pressure resistance, rapid thermal
r
esponse, and exceptional durability. Just like standard
fabricated
t
hermocouples, they serve as reliable sensors for temperature measurement
a
nd are commonly used with display instruments, recording
i
nstruments, and electronic
regulators. Additionally, they
c
an function as the temperature-sensing elements in
assembled
t
hermocouples. They can measure temperatures of liquid
s
team,
gas mediums, and solid surfaces, ranging from 0°C to 1300°C
i
n various industrial
processes.
Features:
Short thermal response time, reducing dynamic tolerance
flexible installation and use
extensive measuring range
high mechanical strength, and superior pressure resistance.
Explosion-proof Thermocouples
Product Brief Introduction:
Explosion-proof thermocouples are typically used with display instruments,
recording instruments,
and electric computers. They can directly measure the temperature
of liquids, steam, gas mediums, and solid surfaces within the range
of 0°C to 1300°C at production sites where hydrocarbons
and other explosive materials are present.
a
nd other explosives.
Features:
Multiple explosion-proof types, delivering excellent explosion-proof performance
Featuring advanced pressure spring sensing elements, this sensor boasts exceptional vibration resistance, ensuring reliable performance even in the most demanding environments.
