Which imported brand of thermal resistor has obtained SIL2 certification?
This post was last edited by Wang Tianze on 2017-7-28 06:59. SIL probably refers to temperature changes; thermal resistance itself should not have such an SIL certification. For example: Rosemount 644 temperature transmitter
The market demanded it, and then it appeared; we had it. But those who know the subject well understand that this device boasts excellent safety and reliability, as it is itself a resistor and does not generate electricity.
Theoretically, it should be like that. Regarding this issue, I specifically talked to a foreign executive in charge of temperature at one of America’s Fortune 500 companies; from his confused expression, I knew the answer right away.
I’ve never heard of thermal resistors having any certifications; I must be uninformed
Which company are you from, and do you have certifications?
Only the SIL certification for the temperature transmitter is required, but when conducting an FMEDA of the temperature transmitter’s failure modes, it is necessary to take into account the failure factors of RTDs or TCs.
I’ve learned that this is how emotions work; therefore, in the case of an integrated temperature control system, both the sensor and the temperature control element must be of SIL2 grade.
Product quality is what matters when it comes to product quality; in my opinion, to truly ensure safety, one needs product quality, along with appropriate accessory solutions and construction plans, as well as redundancy and proper maintenance. Otherwise, having just a SIL level is not sufficient to achieve the actual goal
