• 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 durability with benefits
o
f bending,
high-pressure resistance, and a quick thermal
r
esponse time. They are sturdy and long-lasting.
Similar to fabricated
t
hermocouples, these sensors are used for temperature measurement
a
nd often paired with display instruments, recording
i
nstruments, and electronic
regulators. Additionally, they
c
an serve as the temperature sensing elements in
assembled
t
hermocouples. They can measure the temperature of liquids,
s
team,
gas mediums, and solid surfaces across a range of 0°C to 1300°C
i
n various production
processes.
Features:
• Short thermal response time, reducing dynamic tolerance
• Flexible installation and use
• Large measuring range
• High mechanical strength with excellent pressure resistance
Explosion Proof Thermocouples
Product Brief Introduction:
Typically paired with display instruments,
recording instruments,
electric computers, and more. They directly measure the temperature
of liquids, steam, gas mediums, and solid surfaces within a range
of 0°C to 1300°C in environments containing
hydrocarbons
a
nd other explosives.
Features:
• Multiple explosion-proof types with excellent explosion-proof performance
Featuring advanced pressure spring sensing elements, our sensor offers exceptional vibration resistance, ensuring reliable performance in the most demanding environments.
Boasting an expansive measuring range, this sensor is ideal for a wide variety of applications, providing the versatility and precision you need.
