Low-temperature resistance of the transmitter’s circuitry
Thread Content
If the transmitter is installed in an integrated manner, what is the lowest temperature that the circuit part can withstand? Thank you.
It can be used in outdoor environments across various regions of the country
What I mean is the impact of medium temperature on the circuit section during integrated installation.
Some instruments can operate in the range of -20 degrees to 70 degrees； For special requirements, you can consult the relevant manufacturers regarding their special models. It is related to the selection of electronic components used in instruments; generally, commercial products are chosen ； There are also special instruments available; for example, those designed to detect changes in the pressure beneath geological formations. They can operate at temperatures over 200 degrees and pressures of 10 MPa (I’m not sure of the exact figure), and the chips used in them are of military-grade quality.
As long as the medium temperature exceeds 100 degrees, I design it to be modular.
That’s right; among electronic components, electrolytic capacitors are the least resistant to low temperatures. If the ambient temperature is too low, insulation or heating measures should be taken.
