Is a platinum resistance thermometer shock-resistant?
Thread Content
A temperature sensor is installed not far from the outlet of the material preheater in one tower, using steam to heat the material from room temperature to around 100 degrees. There is significant water hammer vibration. The thermometer is broken now; its resistance is infinite. Did the vibration break the wires inside? Can it be repaired?
If the temperature sensing element is damaged, it is difficult to repair; if the leads are broken, they need to be rewelded. It is recommended to use an armored platinum resistor instead
Thermoresistors have less seismic resistance than thermocouples, so thermocouples can be used.
It can be repaired, or a shock-resistant thermistor can be used instead
Due to the severe water hammer vibrations, it is possible that these vibrations have broken the wires inside. Ordinary thermal resistors have poor resistance to vibrations; therefore, it is recommended to use armored platinum resistors
A thermoresistor with an enclosure will do
A temperature gauge made of stainless steel and filled with oil, capable of withstanding temperatures of 100 degrees, will suffice
Places with strong vibrations experience a higher frequency of damage, and the same is true when we use it.
In areas with heavy vibrations, our factory uses armored thermoresistors; for high temperatures, thermocouples can be chosen
Thank you all for your replies. If it can’t be repaired, we might need to go to another location and install it again. The boss probably won’t agree to getting a shock-resistant watch.
It can be repaired, but the resistance wire is very thin and difficult to solder; a skilled person can weld it together. To prevent it from breaking in the future, it’s better to replace it with an armored one
There are shock-resistant platinum resistors; we also use platinum resistors for temperature measurement and control in heaters. We used ordinary platinum resistors before, which tended to get damaged due to vibrations, but the problem was resolved after switching to shock-resistant ones. It hasn’t been damaged in basically two years.
It is recommended to replace the thermoresistor with an armored one. Vibration-induced damage can basically be overcome.
Haha, with so many people already answering, it’s a bit redundant for me to reply as well. Wishing those who are enthusiastic success in everything they do
It is recommended to use armored platinum resistance thermometers with conical sleeves; the conical sleeve is welded directly to the sampling pipe or equipment, and it has internal threads at its top, onto which the armored platinum resistance thermometer is screwed on. This type of platinum resistance thermometer offers excellent shock resistance
