Dwyer TE-TNS-N063N-00 is a thermowell used to measure temperature in high-temperature environments. It can withstand temperatures up to 1000°F (538°C) for fabricated models and 1200°F (648°C) for machined models. The maximum pressure varies depending on the model, with fabricated models handling up to 140 psi and machined models able to handle 304 SS: 3700 psi or 316 SS: 5500 psi. The construction can be either fabricated (welded) or machined, depending on the specific model.
