Prefabricated Thermocouple
Product Brief Introduction:
Industrial prefabricated thermocouples serve as essential sensors for measuring temperature and are commonly used with display units, recording instruments, and electronic regulators. They can directly measure the temperature of liquids, steam, gases, and solid surfaces within a range of 0°C to 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 superior pressure resistance
Armored Thermocouple
Product Brief Introduction:
Armored thermocouples offer exceptional benefits
o
f flexibility,
high-pressure resistance, and fast thermal
r
esponse, making them both sturdy and durable.
Similar to fabricated
t
hermocouples, they function as temperature-measuring sensors
a
nd are typically used with display instruments, recording
i
nstruments, and electronic
regulators. They can also serve as temperature sensing elements in
c
ombined
t
hermocouples. Capable of measuring the temperature of liquids,
steam,
gas media, and solid surfaces from 0°C to 1300°C
in various production
processes.
Features:
Short thermal response time to minimize dynamic tolerance,
flexible installation and usage,
Large measuring range,
High mechanical strength, excellent pressure resistance
Explosion proof Thermocouples
Product Brief Introduction:
Typically used with display instruments,
recording instruments,
and electronic computers. They measure the temperature
of liquids, steam, gas media, and solid surfaces within the range
of 0°C to 1300°C, especially in environments containing
hydrocarbons
a
nd other explosive substances.
Features:
Multiple explosion-proof types with excellent explosion-proof performance
Crafted with precision, our pressure spring sensing elements offer exceptional vibration resistance, ensuring reliable performance even in the harshest conditions.
Our sensor boasts an impressively large measuring range, making it versatile for a wide array of applications.
Engineered for durability, this sensor features high mechanical strength and superior pressure resistance, guaranteeing long-lasting accuracy.
