Prefabricated Thermocouple
Product Brief Introduction:
Industrial prefabricated thermocouples serve as essential sensors for accurate temperature measurement.They are widely used for monitoring temperaturein conjunction with display units, recordinginstruments,and electric regulators. These sensors can directly measure the temperature of liquids, steam, gas mediums, and solid surfaces within the range of 0°C~2300°C across various industrial processes.
Features:
Easy assembly, simple replacement,and
pressure spring type temperature sensors with excellent anti-vibration performance.
Wide measuring range
High mechanical strength and superior pressure resistance
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples boast distinct advantages
o
f flexibility,
high-pressure resistance, quick thermal
r
esponse times, and exceptional durability.
Similar to fabricated
t
hermocouples, these also measure temperature
a
nd are typically used with display instruments, recording
i
nstruments, and electronic
regulators. Moreover, they can
c
onstitute the temperature sensing element for
assembled
t
hermocouples. They can measure the temperature of liquids,
s
team,
gas mediums, and solid surfaces ranging from 0°C to 1300°C
i
n diverse production
processes.
Features:
Short thermal response time to minimize dynamic tolerance
Flexible installation and usage
Wide measuring range
High mechanical strength and excellent pressure resistance
Explosion Proof Thermocouples
Product Brief Introduction:
Typically used with display instruments,
recording devices,
and electric computers. They directly measure the temperature
of liquids, steam, gas mediums, and solid surfaces within the range
of 0°C to 1300°C, especially in production environments with
hydrocarbons
a
nd other explosive materials.
Features:
Engineered with multiple explosion-proof designs, ensuring superior and reliable explosion-proof performance.
Equipped with advanced pressure spring sensing elements, offering exceptional vibration resistance for stable performance.
Features an expansive measuring range, catering to diverse and extensive temperature monitoring needs.
Boasts high mechanical strength with outstanding pressure resistance, built to endure demanding environments.
