| Summary: Assembly temperature transmitter is composed by setting the two wire system temperature transmitter in the head of assembly thermocouple or RTD.As adopting with common waterproof head, it can not be used in explode-proof and shaking surroundings. It has the virtue of low price that is same with thermocouple and RTD, and also can output 4 ~ 20 ? .DC signals. Its anti-jamming ability is strong and fixing or maintenance is convenient, so it is suitable for using on minor enterprises or temperature measuring of the unimportant point. |

1.When measuring temperature exceeds 500 ? ,the bare length of protection tube should increase from 150mm to 250 mm . 2.When measuring temperature exceeds 850 ? , we should make the sensing part's heat preservation good to avoid temperature overtop of thermocouple head.
3.As regard to B and S,special attention should be paid,almostly avoid selecting all-in-one type.
4.The range in bracket is not recommended. |
