◆ Intrinsic safety and increased safety type thermocouple and resistance temperature detector ◆
● Model : R950 : R951-R952-R953-R954-R955-R956-R957-R958-R95A-R95B-R95C-R95D (ETR10 series)
● Service intended :
Measuring the temperature in the area where combustible gas, particles and flammable liquid exist can be a very dangerous task. The electrical energy of measuring instrument is lower than electric motor, however, the malfunction of the instrument or the accident can cause to start the explosion. Therefore, ETR10 series is explosion proof type product which is designed to be used in a critical danger zone (Ex e=Zone 1, Ex ia=Zone 0) by acquiring IECEx and ATEX certification.
● Examination certificate :
- ATEX II 1/2G Ex ia IIC T6...T1 Ga/Gb
