Selection of remote temperature sensor type: minus 162 degrees Celsius
Thread Content
What type of remote temperature transmitter is used for LNG storage tanks? The temperature in such tanks is minus 162 degrees
JB/T 8622-1997 \"Technical Requirements and Calibration Tables for Industrial Platinum Thermoresistors\" specifies the resistance values of Pt100 thermoresistors in the range of -200~+850°C; they perform well at -162°C as well, offering simplicity and reliability.
The typical operating temperature range for PT100 is from -200 to +200; I agree with the recommendation above regarding PT100
This temperature range essentially falls within the ultra-low temperature category. There are two options: one is to use a low-temperature thermistor, as mentioned on the 2nd floor. Another option is to use a pneumatic bulb filled with an inert gas, which drives the mechanical gauge through a capillary transmission mechanism. Custom products may be required.
