Аюулгүй байдлын хаалтын төрөл ба параметр
From last article, we know how to install Explosion-proof Type Transmitters, in last article, we mention that “The selection about the type and parameter of safety barrier must be referred to the table next article. ” now let’s see the type and parameter of safety barrier.
National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (NEPSI) certified parameter of smart transmitter as following:
Certification number | GYB071520X | Maximum input-voltage | 30V DC |
Explosion-Proof Mark | Ex ia IIC T4 | Maximum input-current | 100 mA |
Environment temperature | -30 ～ +60 ℃ | Maximum input-power | 0.8 W |
Measurable medium temperature | -40～ +110 ℃ | Maximum internal capacity | About 0 |
Maximum internal inductor | 0.11 mH |
Certification number | GYB071520X | Maximum input-voltage | 28V DC |
Explosion-Proof Mark | Ex ia IIC T4 | Maximum input-current | 93mA |
Environment temperature | -30 ～ +50 ℃ | Maximum input-power | 0.66 W |
Measurable media temperature | -40～ +70 ℃ | Maximum internal capacity | About 0 |
Maximum internal inductor | 0.11 mH |
